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.

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.

(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 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
motor rotates counterclockwise as viewed from the rear side, and drives the developer unit, drum,
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.

7.3.2 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

(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.

8.4 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.

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.
(S – K)I = k x ————
(W – K)

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.

(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

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.

(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.
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 Main, Transfer, Separation, and Pre-Cleaning Discharge Chargers,and Transfer Guide Bias and Developer-Bias Control Circuit
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.

material around the toner replenishment orifice
from splattering into the toner cartridge drive
unit when the developer unit is turned upside
down.)
(2) Remove the upper cover (2 screws).
(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.
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.
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”.
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.

15.4.3 Driving of the ADU pick-up roller, ADU feed roller and ADU transport rollers
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.
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.
September 1997 © TOSHIBA 15 - 29 2460 ADU MD-5004
(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.

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.

September 1997 © TOSHIBA 20 - 1 2460 PAGE MEMORY BOARD
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.
