GENERAL PRECAUTIONS REGARDING THE INSTALLATIONAND SERVICE FOR THE COPIER 2460The installation and service should be done by a qualified service technician.

1. Transportation/Installation• When transporting/installing the copier, employ two persons and be sure to use the positions as

indicated below.

The copier is fairly heavy and weighs approximately 83 kg (183 lb), therefore pay full attention

when handling it.

2. Installation• Be sure to use a dedicated outlet with AC 115V/15A (220V, 240V/10A) or more for its power

source.

• The copier must be grounded for safety.

Never ground it to a gas pipe or a water pipe.

• Select a suitable place for installation.

Avoid excessive heat, high humidity, dust, vibration and direct sunlight.

• Also provide proper ventilation as the copier emits a slight amount of ozone.

• To insure adequate working space for the copying operation, keep a minimum clearance of 80

cm (32”) on the left, 80 cm (32”) on the right and 10 cm (4”) in the rear.

• Secure the lifting handles with the fixing plates and screws after the installation is finished.

3. Service of Machines• Basically, be sure to turn the main switch off and unplug the power cord during service.

• Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit, the

damp heater and their periphery.

• Be sure not to touch high-voltage sections such as the chargers and the high-voltage transformer.

• Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fans, etc.

• When servicing the machines with the main switch turned on, be sure not to touch live sections

and rotating/operating sections. Avoid exposure to laser radiation.

• Use suitable measuring instruments and tools.

4. Main Service Parts for Safety• The breaker, door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important

for safety. Be sure to handle/install them properly.

5. Cautionary Labels• During servicing, be sure to check the rating plate and the cautionary labels such as “Unplug the

power cord during service”, “Hot area”, “Laser warning label” etc. to see if there is any dirt on

their surface or whether they are properly stuck to the copier.

6. Disposition of Consumable Parts/Packing Materials• Regarding the recovery and disposal of the copier, supplies, consumable parts and packing

materials, it is recommended to follow the relevant local regulations or rules.

7. When parts are disassembled, reassembly is basically the reverse ofdisassembly unless otherwise noted in this manual or other relateddocuments. Be careful not to reassemble small parts such as screws,washers, pins, E-rings, toothed washers in the wrong places.

8. Basically, the machine should not be operated with any parts removed ordisassembled.

9. Precautions Against Static Electricity• The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband,

because the ICs on it may become damaged due to static electricity.

Caution: Be sure to turn off the copier before attaching the wrist-band.

Always remove the wrist-band before applying power.

3.2. Details of Copying Process(1) Photosensitive Drum

The photosensitive drum has two layers, an

outer and an inner layer. The outer layer is a

photoconductive layer that uses an organic pho-

toconductive carrier (OPC), and the inner layer

is an aluminum, conductive cylindrical sheet.

The resistance held by the drum material

changes (increases, decreases) according to

the strength of the light incident to the

photoconductive carrier.

(Example)

• When incident light is strong, the resistance

decreases (photosensitive drum becomes a

carrier).

• When incident light is weak, the resistance

increases (photosensitive drum becomes an

insulator).

[Formation of Electrostatic Latent Image]

The minus potential on the drum surface

corresponding to black areas of the original are

removed by the charging, scanning, printing

and discharging processes (described later),

and the minus potential remains on areas

corresponding to white areas of the original.

The image on the drum resulting from this minus

potential is called a “latent image” as it cannot

be seen directly by the human eye.

(2) Charging

“Charging” is the process of uniformly applying a

charge to the surface of the photosensitive drum.

The minus corona discharge of the charger wire

is controlled by the grid to charge the drum

surface to a uniform minus potential.

The drum surface potential is determined by

the potential of the grid, and the grid is

determined by the grid control circuit inside the

transformer.

(3) Scanning:

“Scanning” is the process of directing light at

the original, and converting light reflected from

the original to electrical signals.

Light reflected from the original is picked up by

a CCD (charged coupled device), the image

information held by that light is converted to

electrical signals (image signals), and the

image signals are sent to the image processor.

(4) Printing

“Printing” is the process of converting the image

signals sent from the image processor to optical

signals, and exposing these optical signals on

photosensitive drum.

Image signals from the image processor are

converted to optical signals, and these optical

signals are exposed by a semiconductor laser

to form a static latent image on the

photosensitive drum.

(5) Development

• “Developing” is the process of converting the

electrostatic latent image to an image visible

to the human eye.

The developing agent is fed to the surface of the photosensitive drum by the magnetic rollers, and

impressed on the rollers. Toner in the developer agent attaches to areas on the photosensitive drum

having a potential lower than the developer bias (reverse developing method).

• Switching of developing bias polarity

Fogging is reduced by switching the bias of negative d voltage charged areas to positive e polarity

(approx. +150V).

• About Developing Agent

Toner and carrier are mixed. The toner is

charged to minus polarity, and the carrier is

charged to plus polarity by friction caused by

stirring.

Toner: Comprises plastic and carbon.

Carrier: Comprises (i) ferrite and (ii) a

coating layer for stabilizing the

friction charge with the toner on the

surface of the ferrite.

Note:

If the developer material is used for long periods

(beyond its normal life span), toner will become

stuck to the carrier.

The carrier’s (charging) performance is lowered.

Result: 1. Image density is lowered.

2. Toner scattering occurs.

3. Fogging occurs.

Solution: Exchange the developer material.

• Magnetic roller

- Magnetic brush development -

The South and North poles are arranged, as

shown in the figure on the right inside the

magnetic roller. The developer material contacts

the drum forming a brush.

This is caused by the lines of magnetic force

between the South and North poles.

(6) Transfer

• This process transfers the (visible) image

developed on the drum surface by the toner

onto the paper.

• Method: Corona discharge (reverse polarity

of toner) is caused by the transfer

charger to happen to paper passing

under the drum.

The toner moves from the drum

surface onto the paper.

Progress ofpaper

Transfer charger* For smooth transfer, this machine features a transfer bias stage.

The transfer bias process prevents the charge of the transfer charger from flowing to the pretransfer

guide and transport belt unit through the paper by applying the bias voltage (600V DC) to the guide and

belt unit. This is done to improve transfer efficiency.

Normally, the corona discharge is applied by a voltage of 5.0 kV DC. However, to improve transferabil-

ity at the leading/trailing edge of the paper, a higher output (5.4 kV DC) is applied to the 14 mm from the

leading edge of the paper, and a lower output (4.4 kV DC) is applied to the 10 mm from the trailing

edge.

(7) Separation

• At the transfer process, the sheet of paper

becomes temporarily attached to the drum

due to static electricity. The separation

process separates the paper from the drum.

• Method: In addition to a negative d DC bias,

an AC voltage is applied to the

separation charger.

The negative charge on the paper

is decreased.

The electrostatic attraction between

the paper and the drum weakens.

The paper is separated from the

drum by its own weight.

Reference

• Combined use of separation charger and

separation claw.

To prevent the copy paper from failing to be

separated during the operation, due to incomplete

transfer charging, incomplete separation

charging, or absorption of moisture, and thus

jamming up the cleaner, a separation claw

mechanically separates any copy paper which

fails to be separated.

(8) Fixing

The toner on the paper is melted by applying

heat and fixed on the paper.

Method: Melting point of the toner (main

component: resin) is 100°C -

110°C.

(Heat) A heat roller with a surface tem-

perature melts the toner.

plus +

(Pressure) A pressure roller pressured by a

spring solidifies the toner.

(Fixing) Heat and pressure are applied to

the paper going through the two

rollers.

The toner on the paper becomes

fixed.

(9) Pre-cleaning discharge

• “Pre-cleaning discharge” is the process of

removing positive e charge applied on the

drum by the transfer process.

As an OPC drum does not have an optical

discharging mechanism for positive e charges,

AC corona discharge is caused in the same way

as in the separation process by a pre-cleaning

discharge before the cleaning process to

remove positive e charge generated during the

transfer process.

(10)Cleaning

This process collects any toner remaining on

the drum.

Method: The edge of a urethane rubber blade

(main blade) is placed against the

drum surface.

This blade scrapes off the remain-

ing toner from the drum.

Another blade collects the scraped

toner (recovery blade).

The drum surface is cleaned.

(11) Discharge

Erases any electric charge remaining on the

drum after transfer.

If discharge is not performed:

The electric charge remains on the drum sur-

face.

The potential of the drum surface becomes

uneven at charging for the next copy.

The copy image is doubled (the previous im-

age remains).

Method: Discharge LED array illuminates the

entire drum surface.

The drum becomes a conductor.

Since the drum is grounded, the

electric charge escapes.

The drum is ready for the next copy.

[In the case of the Copier and LCF and the pedestal] (When the cassette is installed)

By combining the operation of the tray motor and the condition of the tray-up switch and the empty

switch, the CPU detects whether or not there is paper.

• When the power is turned on or when the LCF door is opened/closed (for the pedestal: when the

power is turned on or when the cassette is loaded) ~

The PFC (Paper Feed Controller) causes the LCF to initialize.

Detects whether or not there is paper

Tray motor comes on ~ The tray rises.

At this time, both tray-up and LCF empty switches are off.

→ A fixed time later, if the tray-up switch is not turned on:

The tray is →

The “ADD PAPER” is displayed regardless

not normal of paper being present or not.

Turning off/on the power clears this condition.

Within a fixed time, the tray-up switch is turned on:

~ The tray motor stops.

At this time, if the empty switch is on ~ It is determined there is paper.

At this time, if the empty switch is off ~ It is determined there is no paper.

The add paper LED comes on.

• During copying, sheets of paper are fed and when the paper supply becomes low

→ The tray-up switch goes off → The PFC turns on the tray motor ~ The tray moves up.

→ The tray-up switch come on → The tray motor stops.

• During copying, when the empty switch goes off despite the tray-up switch being on

It is determined there is no paper.

The add paper LED comes on.

Copying stops.

5.4.2 LED display circuit

(1) Method of LED display

The following description is based on the example of displaying “TIME” on the LED display.

When the signal LDON0-0 changes to “L” level, the transistor is turned on.

Also when pin 6 (D16) of IC1 changes to “L”, a current flows from 5VL via the transistor to LP1

(“TIME”) i.e. LP1 (“TIME”) is turned on.

(2) The circuit is controlled as shown below.

(1) The LGC transmits control signals for main motor rotation. (MAIN-CW/CCW: Direction of rotation,

MAINMTR-ON: Motor rotation command)

(2) The excited phase switching unit excites each phase on the main motor → The main motor runs.

(3) Hall elements A to C are used to detect the rotation position of the motor (or rotor).

(4) The excited phase switching unit switches the excitation for each phase.

(By repeating (2) through (4) above, the motor keeps running.)

(5) The FG pulse is generated by the FG pulse pattern and N/S magnets of rotor installed on the main

motor.

(6) The phases and velocities of the FG pulse and the reference frequency from the LGC are com-

pared, and the differences are added. Further to this are added the fluctuations in the supply volt-

age. (Signal generation)

(7) Changes the switching timing for the excited phase switching unit to match the signal amount ob-

tained in step (6).

i.e. control is done to equalize the FG pulse and reference frequency. → The main motor runs at a

constant speed. (Locked range state.)

(8) When the main motor enters the locked range state, the excited phase switching unit transmits the

PLL-OK signal to the LGC. (“L” level).

(9) When the MTR-BRK from LGC enters “L” level, the main motor rotation is braked, and when the

MAINMTR-ON signal enters “H” level, the main motor stops.

6.4.2 Control signals

(1) MAIN-CW/CCW signal (LGC → MTR: Input)

Switches the rotation direction of the main motor. When this signal becomes “L” level, the main

heat roller, etc.

(2) PLL-OK signal (MTR → LGC: Output)

When the cycle of FG pulse deviation from the reference frequency is within the fixed range, this

state is specified as the lock range (normal rotation), and this PLL-OK signal becomes “L” level.

Also, at this time, the LED “LP1” light comes on.

(3) F-MTR-REF signal (LGC → MTR: Input)

This signal is a reference clock signal for the main motor to rotate at a fixed speed.

(4) MTR-BRK signal (LGC → MTR: Input)

When it becomes “L” level, the main motor rotation is broken down.

(5) MAINMTR-ON signal (LGC → MTR: Input)

7.2 Image Processing Circuit7.2.1 Overview

Unlike existing analog copiers where an original placed on the glass is optically scanned and its reflected

light is directly projected onto a photosensitive drum, this digital copier has an original placed on the

glass optically scanned and its reflected light read by a CCD (charge coupled device) to convert the

optical image into electrical signals. After that, they undergo shading correction (compensation for vari-

ance in the CCD and the light source) and then are output as image signals from the scanner section.

These image signals from the scanner section are input to an image processing section where various

image processing operations are performed on them and the output results from the image processing

section are provided to the printer section.

The above processes are performed by means of ASICs (short for Application Specific IC) made for

specific purposes.

The image processing operation of this copier is done by the IMG board (PWA-F-IMG-220) and the

optional Adaptor board (PWA-F-BRT-776) which is connected by a connector on the IMG board.

7.3 IMG Board (PWA-F-IMG-220)7.3.1 Features

(1) The image processing ASICs are controlled by CPU on the SYS board (PWA-F-SYS-220).

(However, part of the laser related control section is controlled by CPU on the LGC board (PWA-F-

LGC-220).)

(2) The image processing functions of the IMG PC board implement

the following functions:

• High quality image processing

• Image memory editing

• Rectangular area signal generation

• Editing processing

• Gamma correction

• Tone processing

• External system interfacing

• Image area control

• Laser related control

7.3.2 Functional description of the image processing circuit

The two ASICs mounted on the IMG PC board implement the functions described below.

(1) High quality image processing function

(A)Range correction function

This function works to convert image signals to density range width and correct it to match each

original. When copying originals with a certain level of background such as newspapers, it is

possible to reduce the background density by means of this function.

(B) Filtering function

This function is comprised of a low-pass filter circuit and a high-pass filter circuit.

(a) Low-pass filter circuit

By averaging the differences between the target pixel and its adjacent ones, this circuit works to

eliminate image and electrical noise as well as restricting moire to provide an image with high

reproducibility of the original.

For example, assuming the density of the target pixel position to be x and the densities of its

front and back positions to be a and b, respectively, the density of the target pixel position x’ after

low-pass filter operation is given:

For (3 x 1) matrix,

The above operation is performed for all pixel positions to accomplish high original reproducibil-

ity.

The following figure shows the primary scanning pixel is processed by the low-pass filter.

(b) High-pass filter circuit

When an original with sharp image edges (text originals, etc.) are optically scanned and its

image signals are output through CCD, the edges tend to become dull due to the characteristics

of the lens used and other reasons.

To compensate for this phenomenon, edge enhancement operation is performed on the differ-

ences in density between the target pixel and its adjacent ones to accomplish an image with

high reproducibility of the original.

(2) Image memory editing functions

Editing functions such as enlargement/reduction and mirror image copying are performed by using

a line memory. The line memory is used for storing one line of pixel data in the primary scanning

direction and is updated with new pixel data each time the next line is scanned.

(a) Enlargement/reduction function

This function is accomplished by using line memory control in the portion of the operation.

<Example> Enlargement function

<Example> Reduction function

(b) Mirror image function

This function reverses the right side and the left side in the primary direction of the original and

this reversed image is output.

(3) Rectangular area signal generation function

The rectangular area signal is generated by specifying the rectangular coordinate position signal.

This rectangular area signal allows various editing operations to be implemented.

(4) Editing operations functions

Trimming, masking and negative/positive reversal functions are accomplished.

(a) Trimming function

With the rectangular area signal, the image signals inside the rectangular area are left and other

image signals are erased.

(b) Masking function

Using the rectangular area signal, the image data inside the rectangular area are erased with

other image signals left.

(c) Negative/positive reversal function

This function reverses image data from negative to positive or vice versa on the entire area.

(5) Gamma correction function

This function is used to correct the input/output characteristics of the scanner/printer so that image

signals are obtained which have input/output characteristics matching a particular copying mode.

(6) Tone processing function

This function works to process tone so that faithful reproduction of halftone images such as photo-

graphs are accomplished.

(7) Interface to system function

This function performs the input/output control of the interface for the page memory PC board

(PWA-F-PMB-777).

(8) Laser related control

The ON/OFF control of the semiconductor laser and APC (Auto Power Control) are performed by

this function.

(9) Image area control

Effective image areas above and below and to the right and left of the image signal to be output are

set by this function.

8. SCANNER8.1 FunctionsIn this copier’s scanner, light is directed at the surface of the original, and the light reflected from the

original projects to the CCD (Charge Coupled Device) by means of mirrors, lens and a slit. Photo-voltaic

conversion by this CCD converts optical image data to electrical signals. These resultant analog signals

undergo A/D conversion to be converted to digital signals. These digital signals undergo various com-

pensation processes to create the required image. These digital signals are computed and processed,

and then sent to the printer.

8.3 Description of Operation8.3.1 Scanning motor

Rotation of the scanning motor is transmitted to carriages 1 and 2 via the timing belt and carriage drive

wire. First of all, carriage 1 moves to the home position. Home position is detected by carriage 1 passing

the home switch. Carriages 1 and 2 then scan the original when the START key on the control panel is

depressed.

8.4 Drive of the 5-Phase Stepping Motor8.4.1 Features

Up till now, 2-phase hybrid stepping motors having a step angle of 1.8° have been regarded as being the

highest performing motors. Compared to these motors, however, 5-phase stepping motors have the

following features:

(1) A small step angle (full step: 0.72°, half-step: 0.36°) achieves a resolution 2.5 times that of conven-

tional stepping motors. As 2.5 times the number of steps can be used when moving the same

distance, high-speed positioning using optimum acceleration and deceleration is now possible.

(2) Extremely small fluctuation in operating torque achieves little vibration and smooth rotation. This

makes a 5-phase stepping motor ideal for applications where uneven torque and noise are a prob-

lem.

(3) As vibrations are small even at the resonant point, special dampers are not required, and the motor

can be used in all operating ranges.

(4) The self-start frequency is roughly 2.5 times higher than that of 2-phase stepping motors, and

moreover, 5-phase stepping motors do not have a resonant range. This achieves speed control with

a large variable speed ratio without the need for acceleration and deceleration.

(5) Response is much faster than that of 2-phase stepping motors, allowing higher speed setting.

(6) 4- and 5-phase excitation systems achieve excellent damping characteristics.

(7) The step angle can be varied (e.g. 0.72°, 0.36°, 1.44°) depending on the excitation system.

8.4.2 Principle of the stepping motor

The fundamental differences between a 2-phase hybrid stepping motor and a 5-phase stepping motor

are the number of stator main poles and the winding configuration. A 2-phase stepping motor is wound in

a 2-phase, 4-pole configuration, whereas a 5-phase stepping motor is wound in a 5-phase, 2-pole con-

figuration. Fig. 8.4-1 shows the relationship between stator and rotor teeth in a 5-phase stepping motor,

and the winding configuration.

Page 84: 2460SM

September 1997 © TOSHIBA 8 - 7 2460 SCANNER

The stator comprises 10 main poles, with two main poles in apposition forming a single phase. The coil

is wound so that the two opposite main poles are the same polarity (N or S). Assuming a rotor tooth pitch

of τR, the stator teeth are arranged in such a way that the stator teeth on adjacent main poles shift by 0.6

τR with respect to the rotor teeth. This means that the stator teeth on adjacent main poles shift by (0.6-

0.5) τR=τR/10 with respect to teeth on the rotor cup on the opposite side that are shifted by 0.5 τR. Fig.

8.4-2 illustrates this relationship.

Consequently, if the polarity of the stator is moved as shown in Fig. 8.4-3, the rotor rotates clockwise 1/

10th of the rotor tooth pitch at a time.

8.4.3 5-phase motor drive circuit (fixed current type)

The drive circuit mainly comprises the following:

• microstep drive controller (IC1)

• pre-driver (IC2)

• fixed current control IC (IC3)

• drivers (Q1, Q2)

• current detection resistor (R1).

– Excitation Process of Phase A –

1 H.OFF is set to ON (Low).

2 CW/CCW and division data (DATA 0 to 3) are input.

3 After about 10 ms, SCCLK is input.

4 IC6 outputs excitation ON according to the division data from AP to EP (Pch side) and AN to EN (Nch

side). IC3 receives this excitation signal to drive IC1 and flows current to the motor.

Note: This motor is a new pentagonal drive motor. So, when carrying out 4-/5-phase and 5-phase excita-

tion drive, a current of twice that of the set current flows on the motor leads.

8.5 Exposure Control Circuit8.5.1 Overview

[A] The exposure control circuit is comprised of the following four blocks:

(1) Lamp regulator

This causes the exposure lamp to be applied with a voltage corresponding to the duty ratio of the

PWM signal.

(2) CCD sensor circuit

This circuit works to convert the reflected amount of light from the original and the shading correc-

tion plate to the electrical signal. To control the amount of exposure, the circuit reads in the reflected

amount of light from the shading correction plate.

(3) Image processing circuit

This circuit converts output signals from the CCD into binary values and performs a series of image

processing operations such as gamma correction, shading correction, etc.

(4) Control panel

The duty ratio of PWM signal can be set at increments of 1% through the digital keys by the

operator.

Note: The ON/OFF switching of the exposure lamp is carried out by a unique signal (EXPO-ON,J1-10)

separate from the PWM signal.

[B] The exposure control circuit has two functions:

(1) Normal mode

The duty ratio of the PWM signal is controlled at 55% (lamp voltage : 63V)

(2) Check mode

1 Through input from the digital keys, the PWM signal output is varied from 50% - 70% to allow the

exposure to be set arbitrarily.

2 The reflected amount of light from the shading correction plate is taken in by the CCD sensor,

compared with the reference value, and controlled so that the amount of reflected light becomes

closest to the reference value.

8.5.2 Lamp regulator function

The figure below shows a typical characteristic diagram. Control is performed so that a voltage across

the lamp voltage proportional to the duty ratio of PWM signal is produced.

8.5.3 Control section

The control section consists of the folllowing three blocks:

1 Main CPU

Comprised of software, the main CPU calculates the voltage to be applied to the lamp according to

the normal mode and check mode.

2 SRAM with built-in battery

Comprised of IC 42, this is used to store exposure adjustment data such as settings for the duty

width of PWM signal in the check mode so that the optimum exposure is accomplished.

3 PWM timer circuit

This comprised by the following circuit. The data for exposure lamp is converted to PWM signal via

a gate array and is output from the PWM output terminal of the gate array to J1-11 via IC41.

8.5.4 Lamp regulator circuit

The lamp regulator performs control by monitoring lamp current so that the amount of light from the lamp

is maintained at a constant value. In the copier, DC switching ON/OFF is used and the construction of the

lamp regulator circuit is the same as that of the switching power source.

Its principle control is as follows:

(1) AC115V (or 220/240V) power source is rectified to provide DC160V (or 310/340V) which is used as

the power source for the exposure lamp.

(2) The PWM1 signal for light adjustment is averaged by an integration circuit and provides reference

VS for feedback control of the lamp regulator circuit.

(3) When the oscillator circuit is triggered by EXPO-ON/OFF signal, it generates a lamp drive PWM2

signal which turns on the lamp drive transistor (Tr1), causing current I1 to flow through:

Capacitor C → Exposure lamp (L) → Primary side of T1 (P) → Lamp drive transistor (Tr1) → Capaci-

tor C

This causes current I2 proportional to the winding ratio of T1 and the rate of change of I1 to gener-

ated on the secondary side of T1(s).

(4) The amount of lamp current converted to detection voltage VD by a current detection circuit is

compared with the smoothing signal VS of PWM1 signal from the logic circuit by a comparison

circuit whose difference signal VF is fed back to the oscillator circuit.

(5) When the lamp drive transistor (Tr1) is turned OFF, the counter electromotive force of T1 causes

current to flow along:

Primary winding of transformer T1 (P) → Freewheeling diode D1 → Exposure lamp (L) → Primary

winding of tranformer T1 (P)

This causes continuous current I3 to flow through the exposure lamp (L) regardless of the drive

transistor (Tr1) being turned ON/OFF.

8.6 Outline of Control8.6.1 Photo-voltaic conversion

The purpose of photo-voltaic conversion is to form electrical signals corresponding to the intensity of light

reflected from the original. A CCD (Charge Coupled Device) is used for photo-voltaic conversion. CCDs

are single-chip photo-voltaic conversion device in which several thousands of photosensing elements

several microns square are arranged in a single line. This copier uses a CCD having 7,500 of these

photosensing elements.

The photosensor comprises a P-layer, N-layer semiconductor. Optical energy generates a (–) (minus)

charge on the P-layer proportional to the optical energy and irradiation time. The charge generated at the

photosensor is transferred to the transfer area, shifted from left to right in the figure below according to

the transfer clock, and is output from the CCD. During this operation, the reaction speed of the CCD is

slow (it takes time for the charge to be transferred by the shift register), so even-numbered and odd-

numbered image signals are output in parallel.

8.6.2 Shading compensation

The following problems effect the voltage values obtained by photo-voltaic conversion by the CCD:

1 As a light distribution of light source is varied.

2 The reflected light is collected by a lens (the light path is shortest at the CCD center and longest at

the ends), there is a difference in the intensities of light reaching the CCD.

3 The photo-voltaic capacities of each of the 7,500 CCD elements are uneven.

Consequently, these problems must be compensated. This is called “shading compensation.” Shading

compensation involves normalizing optical energy according to the following equation based on

already known scanned black data and white data, and compensating for uneven illuminance of the

image data and device unevenness.

8.7 Automatic Original-Size Detection CircuitThis circuit detects the original size (standard sizes only) using the 3-beam type reflecting photosensor

and 2 reflecting photosensors on the base frame of the optical unit.

8.7.1 Principle of original-size detection

On the base frame of the optical unit, the reflecting photosensor (3-beam type) and 2 reflecting

photosensors. Each photosensor consists of an infrared light emitting diode (light-emitting side LED) and

a phototransistor (light-receiving side). When an original is placed on the original glass, the light emitted

by the LEDs is reflected by the original and led to the phototransistor. In this way, the presence or ab-

sence of an original is detected by whether reflected light exists or not.

8.7.2 Original size detection

(1) If the copier is set in the original size detection mode, the carriage is set at its home position.

(2) Detection is performed in an instant when the platen cover is opened, each sensor receive the

reflecting light and the condition of a matrix shown in (4) are satisfied.

(3) Original size detection is performed when the output signals from each sensor are input to the gate

array (IC33) on the logic PC board.

Supplementary comments

(1) Concerning the reflecting photointerruptor:

The reflecting photointerruptor consists of an infrared diode and a phototransistor. It detects

originals by use of pulse modulation.

The light emitting diode (LED) is driven by pulses with a period of 130 µsec. If a signal which has

the same characteristics is received by the phototransistor, an original is determined to be

present. Pulse modulation is performed within the reflecting photointerruptor.

9. PRINTING9.1 Introduction

Electrical signals which are converted in the scanning portion are processed to the image signals in the

image process portion and the image signals light up the laser diode in the laser drive portion.

The laser beams are irradiated on a photosensitive surface after passing through the lens, polygonal

mirror, fθ lenses and mirrors.

As this set of components is very susceptible to dust, they are assembled in a clean room. Also, they are

adjusted to a high quality.

For this reason, this unit should not be disassembled unnecessarily in the field.

[CAUTION]

• Do not insert tools that are highly reflective into the path of the laser beam.

• Remove all watches, rings, bracelets, etc.

9.2 Structure(1) Laser Unit

The laser unit comprises a laser diode, finite lens and aperture.

1 Laser diode

The laser diode is compact, efficient, low-priced, operates on lower power, and has a long life.

However, it is sensitive to heat.

Laser diode controls emission of laser beams based on the laser control (ON/OFF) signals from

the laser drive board.

2 LASER SAFETY

The beam of the semiconductor laser is itself extremely weak (about 5 mW), but focusing the

parallel rays results in an increase in energy to which extended exposure is hazardous.

The laser optical system of the digital plain paper copier is encased in metal which in turn is

housed in the external cover. There is thus no risk of leaks during use, nor during normal servic-

ing.

Note, however, that the laser beam is not visible, and extreme care must be exercised when

servicing involves focusing the laser. Such operations are hazardous and must not be attempted

unless you are specifically trained to work in this area.

The warning label shown below is attached on the left side of the upper inner cover.

Page 123: 2460SM

2460 PRINTING 9 - 4 September 1997 © TOSHIBA

(2) Polygonal-Mirror Motor Unit

The polygonal-mirror motor unit comprises a

polygonal mirror and a polygonal-mirror motor.

1 Polygonal-mirror motor

The polygonal-mirror motor rotates the

polygonal mirror at high speed.

The DC motor controls the rotation speed of

the mirror as follows:

During standby : 12,000 rpm

During copying (600 dpi) : 22,500 rpm

2 Polygonal mirror

The laser beams emitted from the laser diode

are reflected by this mirror. As the polygonal

mirror is rotated by the polygonal-mirror motor,

the direction of the reflected laser light moves

in sync with the rotation. The direction of

movement is the primary scanning direction of

the image with each single scan ending in one

plane of the polygonal mirror.

As the polygonal mirror has eight planes, eight

scans are completed in one rotation of the

polygonal mirror.

One scan is completed by completion of steps A to C.One scan is carried out on one plane of the polygonalmirror. Eight scans can be carried out with one rotationof the polygonal mirror.

(3) Lenses 1 and 2

These lenses perform the following compensations on the laser light reflected by the polygonal mirror.

1 Equidistant scanning.

The reflected laser light on the polygonal mirror

is scanned at the same angle, because the

polygonal mirror is rotated at the same speed.

That is, when the scan is completed, the dot-

pitch on the drum becomes the wide spaces at

the both edges and the narrow spaces in the

center. So, in order to regularize intervals of

dots, laser light is compensated so that it is

scanned on the drum at equal speeds.

2 Pyramidal error compensation

The reflected face on polygonal mirror is tilted

in either of two directions for the perfect vertical

direction. Deviation of the laser light (for the

perfect horizontal) caused by this reflected

face’s pyramidal error is compensated.

3 The section’s shape of the laser beam on the

drum is compensated.

Wide

Narrow

Drum

Lens 1Lens 2

Equidistant

Mirror plane is tilted. Deviation

(4) HSYNC detection PC board

The laser light, which is scanned by the any reflected face on the polygonal mirror, is reflected by the

HSYNC detection mirror, and becomes incident to the PIN diode on the HSYNC detection PC board.

Then, the primary scanning synchronizing is formed by detection of the laser light.

2460 PRINTING 9 - 6 September 1997 © TOSHIBA

(5) Laser Drive Board

This control board has the following functions:

1 APC control function (for compensating disparity in the laser intensity caused by temperature)

2 Laser ON/OFF generating function

3 Function for generating synchronizing signals in the primary scanning direction

(6) Mirror

The laser light reflected by the polygonal mirror is guided onto the drum by reflection from this mirror.

(7) Slit glass

The slit glass is provided at the position where the laser light is output from the laser unit, and is to

prevent dust as the laser unit is in a sealed structure.

Fig. 9.3-2 shows a block diagram of the semiconductor laser control circuit. The monitor output from the

semiconductor laser is controlled for each of the semiconductor lasers beforehand so that a constant

voltage is maintained when the optical output is 1 mW. After conversion, the voltages are fed back to the

laser power comparison circuit. Here, comparison of the laser power voltage set to the control circuit is

carried out for every single scanning. As a result, when the laser power is insufficient, the forward current

is increased in the laser driver circuit, and alternatively when the laser power is excessive, the forward

current is decreased so that the optical current is constant.

9.3 Laser DiodeThe laser used in this copier is a AlGaAs type semiconductor laser. This semiconductor laser outputs in

the single-horizontal mode, and its oscillation wavelength is about 780 nm. This semiconductor laser is

powered by a + 5 V DC power supply, and its optical output is controlled to about 1 mW. Output of a PIN

diode for monitoring light output built into the semiconductor laser is used for controlling this.

The semiconductor laser has the optical forward-

output current, and monitors the current

characteristics shown in the figure on the right.

Emission of light is started when the forward current

reaches or becomes greater than the threshold

current. A monitor current proportional to the optical

output is output. These threshold currents and

monitor currents are each disparate due to the

characteristics of each of the semiconductor lasers.

Optical output must be adjusted so that it is main-

tained at a constant value. Also, as the optical out-

put of the semiconductor laser drops when its tem-

perature increases, APC is also required to main-

tain the optical output at a constant value.

September 1997 © TOSHIBA 10 - 1 2460 PAPER FEEDING SECTION

10 PAPER FEEDING SECTION10.1 FunctionsThis unit transports paper which is set in the paper cassette or the bypass tray to the transfer position.

The paper feeding section is mainly comprised of manual feed roller, pick-up rollers, paper feed rollers,

separation rollers, transport rollers, aligning roller, manual feed switch, paper empty switch, paper size

switch, paper stop switch, paper aligning switch and also their drive mechanisms.

The following explains each part function.

(1) Pick-up roller/manual feed roller

Feeds paper in the bypass tray or the paper cassette to the paper feed roller and the roller moves up

and down on each occasion of paper feeding.

(2) Paper feed roller

This is the opposite of the separation roller, sending paper fed from the pick-up roller to the transport

roller.

(3) Separation roller

This is the opposite of the paper feed roller. When two sheets or more are fed from the pick-up roller,

the load of the torque limiter of the separation roller is greater than the friction power between the

sheets of paper, the separation roller stops, causing the lower sheet also to stop and not be fed at

that moment. But in the case of single sheet feeding, it rotates at the same timing as the paper feed

roller so that it has the rotation force of that roller.

(4) Transport roller

Transport the paper from the feed roller to the aligning roller.

(5) Aligning roller

Paper fed from the paper feed roller is stuck against the aligning roller which is at rest, and leading

edge alignment is performed.

Then the aligning roller rotates to feed paper to the developing position.

Further, the lower aligning roller is contacted with the brush to prevent paper dust from adhering to

the aligning roller due to paper alignment.

The following explains about switches which detect paper size, paper presence and paper feeding posi-

tion for ON/OFF control of each roller.

(6) Manual feed switch

Detects if paper is set in the bypass tray. If this is the case, manual paper feeding has priority over

cassette paper feeding.

(7) Paper empty switch

This sensor detects paper in the paper cassette by the use of the actuator. When there is no paper in

the cassette, the actuator intercepts the transmitted light in the sensor, causing a paper-empty situ-

ation to be detected.

Page 134: 2460SM

2460 PAPER FEEDER SECTION 10 - 2 September 1997 © TOSHIBA

(8) Paper size switch

Consists of four push-type switches.

In the paper cassette, tabs are installed so that any of these switches (1 to 4) is pressed when a

paper cassette is installed in the copier.

Corresponding to which switch is being pressed, paper size detection is performed.

(9) Paper stop switch

Detects the leading/trailing edge of paper passing through the paper transport roller.

Jam detection such as for paper misfeeding, etc. is also used.

(10)Paper aligning switch

Detects that the leading edge of the paper has arrived at the aligning roller.

Also detects that the trailing edge of the paper has passed through the aligning roller.

If the former is detected, it reads that the aligning roller has completed paper alignment.

10.1.1 Manual pick-up roller vertical movement

When drive power is transmitted to the feed roller, rotation power is sent to the pick-up lever via the spring

clutch. Then the pick-up arm falls by its own weight and the spring clutch stops in the position in which it

has bumped into the stopper.

When the drive power of the feed roller is lost, the pick-up lever is lifted up by the force of the lever spring

after which the pick-up arm is also raised.

10.1.2 Cassette pick-up roller vertical movement

When the cassette is inserted, the cassette lever d pushes up the lever a in the direction A. Then the

pick-up roller is caused to fall by its own weight due to the link mechanism of the levers b and c.

10.1.3 Paper separation operation

Since no paper separation claws are used in the

cassette, a paper separation roller is installed in-

side the machine. The separation roller section

consists of a paper feed roller, separation roller,

spring joint, etc., as shown.

The feed roller is rotated by the feed clutch in the

direction of the arrow ( ) at the same timing

as the pick-up roller.

As shown in the lower right-hand figure, the feed-

ing of two sheets has occurred. Since the friction

between the sheets is smaller, the lower sheet is

stopped being fed any further while the upper sheet

is forcibly transported by the feed roller in the di-

rection of the arrow ( ).

[Example]

When only one sheet of paper 1 has entered into

the separation roller section, since the feed roller’s

transporting force is stronger than the separation

roller’s braking force, the separation roller is forced

to rotate causing the sheet to be sent toward the

aligning roller ( ).

When, two sheets (1 and 2) have entered into

the separation roller section at the same time, since

the powers of the feed roller’s transporting and

separation roller’s braking are greater than the fric-

tion power of the paper, the paper 1 is transported

toward in the direction of the arrow ( ) and

the paper 2 is not transported any further by the

separation roller.

10.2 Cassette Feeding Operations10.2.1 Operation explanation

[A] From power-on until standby status

(1) When the power is turned on for the copier, the tray motors (M13/14) are set to ON and the trays at

each level start to rise. When the trays are raised, the tray-up switches (S28/29) are turned on (L →

H), and the tray motors (M13/14) are turned off, which stops the upward motion of the trays. At this

point, if the empty switches (S3/14) are off (L), it is determined that paper is not present. If the empty

switches are on (H), it is determined that paper is present. The trays stop in their raised position

regardless of whether there is paper or not.

(2) If the power is turned on when the cassette has been removed, the tray motor for that level does not

come on. When the cassette is inserted in the slot, the tray is raised and the presence or absence of

paper is determined.

(3) If either of the paper stop switches (S7/16) or the aligning switch (S8) is ON (because there is paper

in the paper path) when the power is turned on, it is determined that a paper jam has occurred and

operation is not possible until the paper is removed.

[B] Standby mode

(1) After the paper supply is checked by the raising of the trays as described above, the standby mode

is obtained. In the standby mode, the trays remain in their raised position.

(2) When the cassette is inserted or removed in the standby mode, the tray is raised again to check the

paper supply.

[C] Manual feeding

• The manual feed switch detects the presence of manual feeding paper.

• The manual solenoid is turned on and the manual pick-up roller and the manual feed roller are

rotated.

• The manual pick-up roller is lowered and paper feeding is started.

• The leading edge of the paper turns on the paper aligning switch and is aligned at the aligning

roller.

• The manual feed clutch is turned off, the manual pick-up roller and manual feed roller are stopped

rotating, and then the manual pick-up roller is raised.

• The aligning clutch is turned on and the paper is transported to the transfer process.

[D] Cassette feeding (upper or lower)

• The feed clutch and the transport clutch are turned on, the feed roller and the transport roller are

rotated, and then paper feeding is started.

• The leading edge of the paper turns on the paper stop switch, then the feed clutch is turned off.

• The leading edge of the paper turns on the aligning switch and is aligned at the aligning roller.

• The transport clutch is turned off and the transport roller is stopped.

• The aligning clutch is turned on and the paper is transported to the transfer process.

11.5.1 Outline

• Circuit to create the output control voltage Vc of the charging/transfer/separation/developer-bias.

• Vc is varied → output current or voltage varies linearly.

11.5.2 Operation explanation

• Charging/transfer/separation/developer-bias output adjustment value inside BC-RAM is output

to the main processor.

• Outputs control voltage data from the main processor to the D/A converter.

• Analog conversion by the D/A converter.

• Outputs control voltage Vc to the main/transfer/separation/pre-cleaning discharge chargers and

developer-bias transformer.

• The main/transfer/separation/pre-cleaning discharge chargers and developer-bias transformer

generates an output current or voltage proportional to control the voltage Vc.

* Adjustment of control voltage Vc (adjustment data change) is performed in the AJ mode.

* Output value of the transfer guide bias is fixed when the PS-HVT is shipped.

(3) Incline the developer unit and discharge

developer material from the position indicated

by the arrow.

Notes : 1. Do not discharge developer material

from the toner replenishment orifice, as

the developer will adhere to the gear of

the toner cartridge drive motor, causing

the motor to seize.

2. Take care to avoid the connector

becoming smeared with developer

material when discharging is performed.

12.4 Brush Motor (Toner Motor (M15)) Drive CircuitThe toner motor is provided to supply toner for the developer unit.

The toner motor is driven by transistor 2SD1417 (Q2 on the logic PC board), and its circuit is structured

as follows.

The motor winding is connected to the +24V at its (+) side and to the collector of Q2 at its (–) side.

– When PD2 (TMON-0A signal) of the main-CPU becomes “L” level –

• Q11 is turned on → Q2 is turned on

• The +24V power supply supplies current in Q2 via the motor winding → the motor rotates

– When TMON-0A signal becomes “H” level –

• Q11 is turned off → Q2 is turned off

• The current which was flowing in the motor winding flows via the route of diode D5.

~ It decreases at the rate of the time constant determined by the inductance and resistance of the

winding.

14.2 Description of Operations(1) Fuser unit

Heat and pressure are applied to the paper which has been separated from the drum and trans-

ported into the fuser unit, and the toner image is fixed there. Steady pressure is applied always to the

upper and lower rollers by springs and they are rotated by the main motor. (The upper roller (heat

roller) has a heater lamp, but it does not rotate.)

The paper, which has been fixed, is smoothly removed from the heat roller by the use of the separa-

tion claws.

The detection unit monitors the heat roller temperature using a thermistor, and when the temperature

becomes abnormally high, the power supply to the heater lamp is stopped by a thermostat.

(2) Paper-exit unit

The upper and lower exit rollers rotate using the gear drive from the fuser unit.

The paper, which has completed the fixing process, exits smoothly onto the receiving tray through

the upper and lower exit rollers.

14.3 Functions of Each Part(1) Heater lamp

This halogen lamp is located inside the heat roller, where it applies heat to the heat roller. The heater

lamp is secured as it is while the heat roller rotates.

(2) Heat roller

This roller is made of aluminum whose heat conductivity is relatively good, and has heat applied by

the heater lamp. Steady pressure is applied to both the heat and pressure rollers (mentioned later).

Fixing is performed by the transfer paper to be passed between the two rollers as above, so that the

toner image faces the heat roller. The toner is fused by the heat roller, the heat conductivity rate is

increased by the pressure roller, causing the toner to permeate the paper fiber. However, during this

process, a problem may occur. That is, because the toner is fixed by contacting with the heat roller, it

may adhere to the roller (called “offset phenomenon”). Therefore, for easier removal of the toner from

the heat roller, a Teflon coating has been applied on the surface of the heat roller.

(3) Pressure roller

This is made of rubber for smooth application of pressure to the heat roller. The pressure roller has

pressure applied always by springs.

(4) Separation claws/Scraper

By the use of the separation claws/scraper, the paper which has been fixed to the both heat and

pressure rollers, is smoothly removed.

Page 188: 2460SM

September 1997 © TOSHIBA 14 - 3 2460 FUSER UNIT/PAPER-EXIT UNIT

(5) Cleaning felt roller

This cleans the toner remaining on the drum at the fixing process. The cleaning felt roller is located

so that it can come in contact with the heat roller. The silicon oil soaked in the pressure roller is

evaporated by the heat roller, causing it to adhere to the surface of the heat roller. As a result, the

cleaning of the toner on the heat roller can be smoothly performed.

(6) Thermistor-1

Surface temperature of the heat roller should be maintained within a fixed range, (actually, around

200 °C), i.e. higher than the minimum temperature at which improper fixing may occur, lower than the

maximum temperature at which “baking” may occur. The thermistor detects the surface temperature

of the heat roller. If the temperature is lower than the standard one, it turns on the heater lamp, if

higher it turns it off.

(7) Thermistor-2

Temperature distribution in the axis of the heat roller may differ greatly at its center and ends accord-

ing to conditions. The thermistor-2 detects the temperature of the heat roller end.

When either thermistor-1 or -2 detects the temperature over the specifieds, heater lamp is turned off

by their thermal controls.

(8) Thermostat

When the surface temperature of the heat roller becomes excessively high due to thermistor failure,

etc., the thermostat stops the power supply to the heater lamp.

As the thermostat used in this copier is a type which protects against abnormal operation, when it

detects an abnormal operation, it is set to stay OFF. Therefore, during repair, this should be replaced

together with other damaged parts in the fuser unit.

(9) Exit rollers

Through the exit rollers, the paper removed by the separation claws or scraper exits smoothly onto

the receiving tray via the ADU exit roller.

Page 189: 2460SM

2460 FUSER UNIT/PAPER-EXIT UNIT 14 - 4 September 1997 © TOSHIBA

14.4 Heater Control Circuit14.4.1 Temperature detection unit

To maintain the heat roller temperature, this unit detects the heat-roller temperature by thermistor-1, and

then performs heater lamp ON/OFF control.

The thermistor is an electrical element whose resistance decreases as its detected temperature in-

creases. If the thermistor is open-circuited, the control circuit erroneously determines that the fuser tem-

perature is extremely low and continues to energize the heater lamp. As a result, the fuser temperature

rises abnormally high, possibly activating the thermostat provided for safety purposes. The CPU works

to detect the breakage of the thermistor and prevents the condition mentioned above.

The following abnormalities are detected:

(1) Abnormal detection during warming up

25 sec. after the power has been turned on, if the thermistor output voltage does not exceed 0.078 V,

CALL SERVICE (C41) is displayed.

(2) Abnormal detection during stand-by/copying (Thermistor-1)

If the thermistor-1 output voltage decreases to and remains at 0.078 V or lower for 500 msec. or

more, CALL SERVICE (C43) is displayed.

(3) Abnormal detection during stand-by/copying (Thermistor-2)

If the thermistor-2 output voltage decreases to and remains at 0.192 V or lower for 260 msec. or

more, CALL SERVICE (C45) is displayed.

(4) Thermistor status counter control

• For improved fuser-unit safety, the CPU works as follows: After a C41 error occurs two times in

succession, even when the power is turned on, the heater will not come on and the C41 error will be

immediately displayed.

• However, with “1” or less stored in the Thermistor status counter, if the copier becomes ready cor-

rectly, the Thermistor status counter clears to “0”.

• After CALL SERVICE (C41 – C45) has occurred and the thermistor, heater lamp, etc. have been

repaired (or replaced), if turning on the power switch does not cause the heater to energize resulting

in an error, check the Thermistor status counter (08-code 400) and reset it to “0”.

Page 190: 2460SM

September 1997 © TOSHIBA 14 - 5 2460 FUSER UNIT/PAPER-EXIT UNIT

Surface temperature of heat roller: 190°C (Thermistor resistance value: about 4.0 kΩ)

Reference

1. A value other than 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9 is never written in the Thermistor status counter.

• At the power on, if the heater is not turned on and the copier goes into C41 CALL SERVICE, check theThermistor status counter to see if it is 2 or more. If it is 2 or more, be sure to check the thermistor andheater lamp, and after repair, reset the Thermistor status counter (08-code 400) to 0 and then turn onthe power switch.

• If the value of the Thermistor status counter is more than 10 (11, for example), it may be possible thatBC-RAM or the data in it have been destroyed by charger leaking, etc. In this case, check the guidebias, high-voltage transformers, charger wires, etc. for any defects. Also, all the data inside BC-RAM

need to be rechecked.2. Relationship between the output voltage and the fusing temperature.

• 190°C corresponds to approx. 2.5V and 0.078 V corresponds to approx. 40°C.

3. Relationship between heat roller surface temperature and thermistor-1 resistance.

4. Temperature control at heat roller ends

During multicopying, the temperature at each end (no paper-contact area) of the heat roller normally tendsto rise higher than the controlled temperature of the paper-contact area. Therefore, the circuit is so de-vised that if the temperature in the no paper-contact area rises to 220°C, the second thermistor detects

this, causing the heater to be turned off immediately regardless of the temperature in the paper-contactarea.

14.4.3 Control for abnormal heater condition

When something abnormal occurs in the heater turn-on circuit, such as a shorted triac, it may become

incapable of ON/OFF control. In this case, the microcomputer detects abnormal temperatures through

the first and second thermistors, determines the corresponding error codes and counter values, and

causes the main power to switch off to protect the fuser unit.

(1) Temperature detection

The following abnormal temperatures are detected by the respective thermistors:

First thermistor: 230°C

Second thermistor: 270°C

(2) Error codes

“C44” : Displayed when keys C/S + 8 are pressed simultaneously at the time of Call

Service.

Counter value “9”: Displayed when you input “400” in the AD (0 + 8) mode.

(3) Machine condition

After de-energizing all outputs (heater lamp, exposure lamp, control-panel displays, motors, etc.),

the microcomputer causes the main power to switch off.

(4) Corrective action

After the error code and counter value in (2) have been determined, abnormal temperature detection

in (1) continues. So, if the main switch is turned on immediately, it will be turned off again as long as

the temperature on the heater surface remains above the abnormal detection temperatures of

thermistors. Thereafter, this will be repeated. So, after waiting for the heater surface temperature to

drop, turn on the main switch and you can check the counter value before the main switch is turned

off again. After confirming that an abnormal heater condition has occurred, repair the problem and

then clear code 400 of the AD (0 + 8) mode with “0”. After that, you can bring the copier into its

normal operating condition.

15.3 Description of ADU Operation15.3.1 Paper stacking operation

When the ADU (duplex copying) mode is selected and the START key is pressed on the copier’s control

panel, the ADU motor starts rotating, and the side guides and the end guide in the stacking section are

moved to the positions corresponding to the selected size of paper by their respective motors. Then, the

stack clutch comes on, the transport roller rotates and the EXIT/ADU selection gate is switched in the

direction of the stacking section by the gate solenoid.

The copy paper which has exited from the copier is sent into the ADU’s open guide by the EXIT/ADU

selection gate. This paper is further carried by transport rollers into the stacking section, where the paper

is stacked face up. This operation is repeated until the specified number of sheets are stacked.

At the start of the stacking operation, the side guides are set with a 5 mm gap relative to each side of the

paper, and each time 5 sheets are stacked consecutively during stacking, the side guides perform a

paper aligning operation.

A jam switch is provided to have paper jams in the open guide detected. The empty switch is to detect

whether or not paper is present in the stacking section.

15.3.2 Duplex copying

After the paper stacking operation, when a second original is set and the START key is pressed, the

ADU motor starts rotating, causing the elevator arm to rotate. This will cause the tray positioned under

the stacked sheets of paper to rise, making the sheets come into contact with the rotating pick-up roller

and sending the topmost sheet out. The separation roller rotates with the feed roller. At this time, if two or

more sheets are sent out, the separation roller stops rotating, causing the lower sheet(s) to stop its

movement.

The sheet of paper thus sent out is carried by the copier’s upper transport roller to the copier’s aligning

roller and aligned. The sheet is then copied on the side not copied previously. The sheet copied on both

its sides passes through the copier’s exit roller and over the EXIT/ADU selection gate which is already

positioned in the direction of exiting, further passing through the exit roller to exit finally into the receiving

tray.

15.4 Drive System15.4.1 Driving of the EXIT/ADU gate

When the gate solenoid is turned on, the arm

rotates and pushes up the lever, causing the

gate to open. The copied sheet is then trans-

ported to the ADU’s stacking section. When

the gate solenoid is turned off, the arm is

pulled back to its original position by a spring,

causing the gate to close, and the copied

sheet will exit.

Transport rollers

Z57/Z28

• When the ADU motor rotates in the direction of the arrow A and stack clutch (Z45) energizes, the

transport rollers are rotated and the ADU stack/feed roller is rotated in the direction of the arrow B (in

the stacking direction).

• When the ADU motor rotates (arrow A) and the feed clutch (Z28) energizes, the pick-up roller and

the ADU stack/feed roller are rotated in the feeding direction (arrow C).

At this time, the transport rollers do not rotate since a one-way clutch is contained inside of the gear

(Z16) on the transport roller shaft.

15.8 Description of Operation15.8.1 General operation

(1) Initializing

When the power switch is turned on or when the front cover is opened/closed or when the ADU is

pulled out/pushed in, this operation is performed.

(2) Stacking operation

This is an operation in which sheets of paper fed from the cassette and copied on their surface (first

side) are sent into the ADU stacking section and stacked there.

(3) Duplex copying

Sheets of paper which have been copied on their first sides are automatically sent into the copier and

copied on their reverse surface (second side).

(4) ADU paper feeding

This operation causes sheets of paper to be fed from the ADU into the copier.

15.8.2 Description of each operation

[A] Initializing

[A-1] Initializing when the power switch is turned on

(1) When the power switch is turned on, the end motor (END-MTR) DM2 rotates to move the end

guide in the stacking section to its home position.

(2) The side motor (SID-MTR) DM3 rotates to move the side guides to their home position.

[A-2] Initializing when the copier’s front cover is opened/closed

(1) The operation in step (1) above is performed.

[A-3] Initializing when the ADU is pulled out/pushed in

(1) The end motor (END-MTR) DM2 rotates to move the end guide to its home position once,

then moves it to the position corresponding to the selected size of paper.

(2) The side motor (SID-MTR) DM3 rotates to move the side guides to their home position once,

then moves them to the position corresponding to the selected size of paper.

[B] Stacking operation

(1) When the START key is pressed, the SID-MTR DM3 and END-MTR DM2 are rotated to

move the side and end guides to the position corresponding to the specified size of paper, and

the ADU-MTR DM1 is rotated clockwise to transport the paper. STSOL ( SOL1 ) is en-

ergized to position the EXIT/ADU selection gate in the direction of stacking, and STCLT CLT2 is

energized to rotate the ADU transport rollers in the direction of stacking.

(2) Jam detection inside the ADU is performed as follows:

JAM-SW SA4 is checked if it is turned on within a specified period of time after the copied

paper has turned on the copier’s exit switch. The switch is also checked if it is turned off within a

specified period of time after the exit switch was turned off by the paper.

Page 230: 2460SM

2460 ADU MD-5004 15 - 28 September 1997 © TOSHIBA

(3) Each time five sheets of paper are stacked in the ADU, the side motor (SID-MTR) DM3 is

rotated to move the side guides so that the sheets stacked are aligned, then the side guides are

returned to their previous position.

(4) The above procedure (2)~(3) is repeated until the specified number of copies are made.

(5) After the final sheet is stacked in the ADU stack section, STSOL ( SOL1 ), STCLT

CLT2 and ADU-MTR DM1 are turned off.

[C] Feeding from ADU

(1) When the START key is pressed, the SID-MTR DM3 is rotated to move the side guides to

the specified size of paper and ADU-MTR DM1 is rotated clockwise and FEDCLT CLT1 is

turned on, causing the ADU feed roller and pick-up roller to rotate.

(2) Due to the operation in (1), the ADU tray is raised, causing the copy paper to come into contact

with the pick-up roller for paper feeding.

(3) A sheet of paper is fed out of the ADU and transported toward the copier’s aligning roller.

(4) When the sheet pushes the copier’s paper transport switch on, FEDCLT CLT1 is turned off,

causing the pick-up roller and feed roller to stop rotating.

(5) Then, the copier’s aligning roller starts rotating, and the copying process commences.

(6) The above procedure (2)~(5) is repeated until the specified number of copies are made. When

copies are finished, ADU-MTR DM1 is stopped rotation.

[D] Duplex copying

(1) When the first-side copying operation is started, ADU-MTR DM1 is rotated, and the side and

end guides are moved to the position of specified paper size by the SID-MTR DM3 and END-

MTR DM2 .

Additionally, the STSOL ( SOL1 ) and the STCLT CLT2 are turned on in the same way as

the [B] Stacking operation.

(2) The first-side copied sheet is transported into the ADU from the copier exit switch and gate

sections, and then stacked through the JAM-SW SA4 .

The ADU inside jam symbol comes on when the JAM-SW SA4 is not turned on within a

specified time after the copier exit switch is turned on, or the JAM-SW is not turned off within a

specified time after the copier exit switch is turned off.

(3) Each time five sheets of paper are stacked, the stacked sheets are aligned by the side motor

SID-MTR DM3 moving the side guides.

(4) The above procedure (2)~(3) is repeated until the specified number of sheets are stacked.

(5) The final sheet is stacked in the ADU, and then STSOL ( SOL1 ) and STCLT CLT2 are

turned off.

(6) When the RADF is not used, ADU-MTR DM1 is stopped once to turn over the original. After the

original has been turned over, ADU-MTR DM1 is rotated again to make a copy of the next

original in step 7 or later.

When the RADF is used, ADU-MTR DM1 is not stopped since the original is turned over

continuously.

(7) When the second-side copying is started, the side guides are moved by the SID-MTR DM3 to

the specified size position.

(8) When the FEDCLT CLT1 is turned on, the ADU paper feed tray is lifted up, and also the pickup

and feed rollers are driven, then one sheet of paper is separated and fed.

When the sheet reaches the copier’s transport switch, the FEDCLT CLT1 is turned off.

The ADU feed jam symbol comes on when the copier’s transport switch is not turned on within a

specified time after the FEDCLT CLT1 is turned on.

(9) The above step (8) is repeated until the specified number of copies are made. After copying has

been finished, ADU-MTR DM1 is stopped.

15.8.4 Detection of abnormal status

When an abnormal condition is detected inside the ADU, a symbol corresponding to the condition is

shown on the copier’s control panel. The following kinds of abnormal statuses may be encountered:

(1) Abnormal statuses which can be cleared without pulling out/pushing in the ADU:

• Paper misfeeding which occurs while paper is being fed from the stacking section.

(2) Abnormal statuses which can be cleared by pulling out/pushing in the ADU:

• Paper misfeeding in the paper stacking section.

(3) Abnormal statuses which can be cleared only by turning off/on the copier’s power switch:

• When the side guides or end guide cannot be initialized to their correct positions.

[A] Paper misfeeding

(1)Paper misfeeding during duplex copying:

While paper is fed from the ADU, if the copier’s P-STP-SW is not turned on within about 1 sec.

after FEDCLT CLT1 was energized, it is judged that paper misfeeding has occurred during

ADU paper feeding, and a paper misfeed symbol is displayed. This condition can be cleared by

opening/closing the copier’s side cover.

(2)Paper misfeeding during paper stacking:

During paper stacking, if the ADU’s JAM-SW SA4 is not turned on within about 3 sec. after the

copier’s EXIT-SW was turned on/off, it is judged that paper misfeeding has occurred inside the

ADU. To clear this condition, pull out the ADU, remove the misfed sheet, then push in the ADU. (If

necessary, open/close the copier’s front cover.)

[B] Abnormal statuses at power on

(1)Paper remaining in the stacking section at power on:

If a sheet of paper is left in the stacking section when the power is turned on, a symbol indicating

that paper is still there is displayed on the copier’s control panel when the duplexing mode is

selected. This mode cannot be started until the paper is removed.

(2)Misfed paper remaining inside the ADU when the power is turned on:

If a misfed sheet of paper remains on the ADU’s paper path when the power is turned on, the ADU

misfeed symbol is shown. To clear this condition, pull out the ADU, remove the misfed sheet and

then push in the ADU. (If necessary, open/close the copier’s front cover.)

[C] “Serviceman Call” errors

(1)The paper side guides and end guide cannot be initialized :

During the initialization of the SID-MTR DM3 and END-MTR DM2 , if the respective home

switch positions are not detected, a message will be displayed indicating that the ADU cannot

function.

September 1997 © TOSHIBA 17 - 1 2460 POWER SUPPLY UNIT

17. POWER SUPPLY UNIT17.1 StructureThe power supply unit is comprised of two circuits: an insulation-type DC output circuit and an exposure-

lamp energizing circuit. (See Fig. 17.1.)

(1) DC output circuit

The DC output circuits used are roughly divided into the following three areas:

1 System related: Power supply mainly used for the SYS board for 24 hours. It provides four volt-

age outputs (+3.1V, +5.1V, +12V and –12V) which rise up when the power switch

is turned on.

2 Main-body related: Power supply used by the entire machine during image formation. It provides

four voltage outputs (+3.3V, +5.1V, +12V and –12V) which start up with a

signal from the SYS board.

3 Door-switch related: Power supply provided via the door switch and used by the entire machine

during image formation. It provides three voltage outputs (+5V, +24V and

+36V) which rise up with a door-switch-on signal as well as a signal from

the SYS board.

(2) Exposure lamp energizing circuit

A halogen lamp is used as an exposure light source for illumination, but its energizing circuit uses a

DC (high-frequency chopper) fixed-voltage control method instead of a phase-angle control fixed-

voltage method normally used with analog PPCs. This is because a line-type CCD sensor is used as

the device for reading originals in this machine in order to prevent the light source’s variance in the

amount of light (flickerring occurring in sync with power supply frequency cycles on a phase-angle

control method) from appearing on output images.

17.2 Operation of DC Output Circuit(1) Starting up

When the main switch of the machine is turned on, an AC power is supplied to switching regulator 1

(REG1), causing the four outputs of the system-related DC circuits to rise up. After the SYS-CPU has

risen up, when a power-supply control signal (PWR-EN) is produced (‘L’ level), the main-body related

four outputs start up. At this time, if the door switch of the machine is on (cover closed), an AC power

is supplied to switching regulator 2(REG2), causing the door-switch related three outputs to rise up.

(2) Terminating

When the main switch of the machine is turned off, a power-off signal (PWR-DN) is produced (Hi-z:

high impedance) after the instantaneous outage assurance time (at least 20 msec.) has elapsed.

The output of regulator 1 (for system/main-body related) is maintained for the minimum retaining

time (at least 15 msec., though varying with AC inputs and load capacity) at its rated value, then

starts dropping.

(3) Output protection

Each circuit is provided with both overcurrent protection circuit (fuse and series regulator’s internal

protection included) and overvoltage protection circuit (±12V system/main-body related circuits ex-

cluded). This is to prevent anomalies such as damages or abnormal operations in the secondary

circuits which could occur due to an overcurrent caused by shorted loads or an overvoltage caused

by short-circuits between disparate-voltage circuits.

When a protection circuit has operated, eliminate the cause of the anomaly (if a fuse has blown out,

it must also be replaced) and turn on the power switch again to restore the protection circuit. If you

switch on the power too quickly (within 30 seconds after the protection circuit has operated), the

protection circuit may not be restored.

17.3 Operation of the Exposure Energizing Circuit(1) Control method

After an AC input is rectified, it is made into a fixed DC voltage by a chopper regulator. As in the

phase-angle control method (used for analog PPCs), a soft start concept is provided to prevent lamp

degradation due to rush current if a cold start is made to energize the exposure lamp.

(2) Safety circuit

An AC input is provided through the door switch to this circuit. In addition, a voltage shutoff circuit

operated by the control signal and an overcurrent protection circuit for a short circuit are provided.

(3) Control signals

An output enable signal (EXPO-EN) is provided to allow the voltage to the exposure lamp to be shut

off with a view to product safety. While this signal is on (‘L’), a voltage obtained by rectifying an AC

input (approx. 1.4 times the power supply voltage) appears across the lamp (against FG). (Under this

condition, the voltage is only applied but no electrical current path is formed. This maintains both

ends of the lamp at the same voltage and the lamp does not come on.)

An output-on signal (EXPO-ON) is a signal to control power supply to the lamp with the output enable

signal being on. When this signal is on (‘L’), power is supplied so that the potential difference across

the lamp becomes the set voltage, causing the lamp to come on.

(4) Setting the voltage applied to the lamp

When a PWM signal with a frequency of 1 kHz±20% (‘L’ period represented in %) is input to the

voltage setting signal (EXPO-PWM) outside of the power supply, the voltage applied to the lamp can

be set, and the higher the value, the higher the voltage applied to the lamp.

20 PAGE MEMORY BOARD20.1 IntroductionThe page memory board stores digital image data scanned on the digital copier in page units so that

editing functions such as rotation and sorting can be applied before output.

The page memory board supports the following basic functions.

1 Scanning : Writes digital image data scanned on the digital copier into the page

memory.

2 Printing : Outputs image data in the memory to the printer.

3 Compression/decompression :

Compresses image data when writing image data to memory at the

scanner processor, and decompresses the image data when

outputting to the printer at the printer output processor.

4 Editing : Executes the following processes on the image data saved in the

page memory:

• Makes multi-image copies.

• Rotates images.

The above processes are processed simultaneously in parallel by time-division processing. These proc-

esses are also combined to achieve digitally various other processes such as sorting.

20.2 StructureThe page memory board is located on the left and front side of the system board when the rear cover and

PC board cover are removed.

20.2.1 Interfaces

Connector J81 on the page memory board (PWA-F-PMB-777) connected to connector J 72 on the sys-

tem PC board (PWA-F-SYS-220), and handles signals on the following interfaces.

1 I/O interface

CPU on the system PC board handles the control data for controlling the page memory board.

2 Scanner interface

Image data scanned by the digital copier are loaded to page memory from the external interface of

the digital copier image processor.

3 Printer interface

Image data in page memory are output to the laser controllers in the digital copier’s printer by the

external interface of the digital copier image processor.

20.2.2 Schematic

The figure below shows a schematic diagram of the page memory board.

Page Memory Board Schematic

(2) Page memory control ASIC (DRC)

(2-1) Address control

This ASIC forms the address on the page memory when the following conditions are met:

• When digital image data are written to the page memory, and

• When digital image data in the page memory are read.

(2-2) Data control

This ASIC executes the following operations:

• Controls the image bus on the page memory board.

• Receives and waits for image data transfer control between the compression /decompression

LSI and the page memory.

• Merges image data in the page memory with image data scanned by the digital copier, and

writes image data into the page memory.

(2-3) Rotation/merge control

This ASIC executes the following operations:

• Receives and waits for digital image data transfer control between the digital copier and the

page memory PC board on the scanner and printer interfaces.

• Swaps data in the page memory during rotation processing.

(3) Compression/decompression LSI (PM2m)

This LSI executes the following operations:

• Compresses image data on the page memory, and forms coded data.

• Decompresses the coding data compressed on the page memory to restore the image data.

20.3 Description of Functions20.3.1 Basic functions

(1) Alternation

This operation is achieved by the page memory board compression/decompression and rotation

functions. The orientation of multiple copies is switched for each copy or by each page at a time,Alternation assumes that a cassette of the same paper size having a different orientation is installed

in the digital copier.

Example:

The following describes an example where alternation and sorting (see (2) below) have been speci-

fied when making three copies of three A4-sized originals using the ADF.

September 1997 © TOSHIBA 20 - 5 2460 PAGE MEMORY BOARD

(2) Sort copying

This operation is achieved by the compression/decompression function on the page memory board.

The image data of two or more originals are stored temporarily in the page memory while being

compressed. Image data stored in the page memory are then decompressed at each page, and

printed. Assuming that printing of N number of copies has been set, decompression and printing at

each page are repeated for N number of times.

(3) Group copying

In the same way as for sort copying, this operation is achieved by a compression/decompression

function. The image data of the 1st original are stored in the page memory while being compressed.

Then, the image data of the 1st original data are decompressed, and printed repeatedly for the

preset number of times. The same operation is repeated for the 2nd original onwards.

On a digital copier, a single scan is sufficient for N number of copies. However, on an analog scanner,

N number of scans must be carried out.
