1. Installation Precautions

WARNING

• Do not use a power supply with a voltage other than that specified. Avoid multiple connections toone outlet: they may cause fire or electric shock. When using an extension cable, always checkthat it is adequate for the rated current. ............................................................................................

• Connect the ground wire to a suitable grounding point. Not grounding the copier may cause fire orelectric shock. Connecting the earth wire to an object not approved for the purpose may causeexplosion or electric shock. Never connect the ground cable to any of the following: gas pipes,lightning rods, ground cables for telephone lines and water pipes or faucets not approved by theproper authorities. .............................................................................................................................

CAUTION:

• Do not place the copier on an infirm or angled surface: the copier may tip over, causing injury. .....

• Do not install the copier in a humid or dusty place. This may cause fire or electric shock. ..............

• Do not install the copier near a radiator, heater, other heat source or near flammable material.This may cause fire. ..........................................................................................................................

• Allow sufficient space around the copier to allow the ventilation grills to keep the machine as coolas possible. Insufficient ventilation may cause heat buildup and poor copying performance. ..........

• Always handle the machine by the correct locations when moving it. ..............................................

• Always use anti-toppling and locking devices on copiers so equipped. Failure to do this maycause the copier to move unexpectedly or topple, leading to injury. .................................................

• Avoid inhaling toner or developer excessively. Protect the eyes. If toner or developer isaccidentally ingested, drink a lot of water to dilute it in the stomach and obtain medical attentionimmediately. If it gets into the eyes, rinse immediately with copious amounts of water and obtainmedical attention. ..............................................................................................................................

• Advice customers that they must always follow the safety warnings and precautions in the copier’sinstruction handbook. ........................................................................................................................

Any differences between the values at machine front and rearindicates that scanner problem causes the fixing unevenness.If the displayed results indicate no shading problems, the fixing unevenness (uneven copy density) iscaused by factors other than in the scanner section (shading or CCD).If a black line appears, the cause may assumed to be based on the results of the scanning operation beforeshading: if a white line appears, they may be assumed based on the results of the scanning operation aftershading. Note that depending on the thickness and location of the black or white line, it may not be possibleto use this method to determine the cause. This is because the displayed values obtained from scanning atthe limit of nine points are insufficient to provide significant information.

2-1-1 Paper feed section

The paper feed section consists of the primary feed and secondary feed subsections. Primary feed conveys paper fromthe upper drawer, lower drawer or bypass tray to the left and right registration rollers, at which point secondary feedtakes place and the paper travels to the transfer section in sync with the printing timing.

Each drawer consists of a lift driven by the lift motor and other components. Each drawer can hold up to 500 sheets ofpaper. Paper is fed from the drawer by the rotation of the forwarding pulley and paper feed pulley. The separation pulleyprevents multiple sheets from being fed at one time, via the torque limiter.

2-1-4 Developing section

The developing section consists of the developing unit and the toner container.The developing unit consists of the developing roller where a magnetic brush is formed, the doctor blade and thedeveloping spirals that agitate the toner.When the toner sensor (TNS) detects a low toner level in the developing unit, the toner replenishment signal is output tothe main PCB (MPCB). The main PCB (MPCB) that has received the signal turns on the toner replenishment solenoid(TNFSOL) and replenishes toner from the toner container to the developing unit.Also, the toner container sensor (TCS) checks whether or not toner remains in the toner container.

(1) Formation of magnetic brushThe developing roller consists of a magnet roller with four poles and a sleeve roller. Rotation of the sleeve roller aroundthe magnet roller entrains toner, which in turn forms a magnetic brush at pole N1 on the magnet roller. The height of themagnetic brush is regulated by the doctor blade; the developing result is affected by the position of the poles on themagnet roller and the position of the doctor blade.A developing bias voltage generated by the high-voltage transformer PCB (HVTPCB) is applied to the developing rollerto provide image contrast.

(3) Single component developing systemThis machine uses the single component developing system, and reversal processing is performed with a + chargeddrum (a-Si) and a + charged magnetic toner.With the single component developing system, toner is electrically charged by friction with the developing sleeve and +charged when it passes through the magnetic doctor blade. The toner that has passed through the magnetic doctorblade forms a uniform layer on the developing sleeve. When the toner layer comes to the location where the developingsleeve is the nearest to the drum, toner moves between the drum and the developing sleeve by an electric field of themagnetic pole. Then, when the developing sleeve rotates and passes through the nearest location to the drum, on theportion of the drum that has been exposed to light, toner is attracted toward the drum by potential difference between thedeveloping bias and the drum surface and development is performed. On the other hand, on the portion of the drum thathas not been exposed to light, toner is attracted toward the sleeve and development is not performed. When tonercomes to an area where the gap between the drum and the developing sleeve is large, an electric field disappears andtoner does not leave the developing sleeve. Development is complete.

2-1-7 Fixing section

The fixing section consists of the parts shown in Figure 2-1-22. When paper reaches the fixing section after the transferprocess, it passes between the press roller and heat roller, which is heated by fixing heaters M or S (FH-M or FH-S).Pressure is applied by the fixing unit pressure springs so that the toner on the paper is melted, fused and fixed onto thepaper. The heat roller is heated by fixing heaters M or S (FH-M or FH-S) inside it; its surface temperature is detected bythe fixing unit thermistor (FTH) and is regulated by the fixing heaters turning on and off.If the fixing section becomes abnormally hot, fixing unit thermostat (FTS) operates shutting the power to the fixingheaters off. When the fixing process is completed, the paper is separated from the heat roller by its separation claws andis conveyed from the copier to eject and switchback section.

The power source PCB (PSPCB) is a switching regulator that converts an AC input to generate 24 V DC and 5 V DC. Itincludes a rectifier circuit, a switching regulator circuit, a 24 V DC output circuit, a 5 V DC output circuit and a fixing heatercontrol circuit.The rectifier circuit full-wave rectifies the AC input using the diode bridge D3. The smoothing capacitor C5 smoothes out thepulsed current from the diode bridge.In the switching control circuit, PWM controller IC1 turns the power MOSFET Q1 on and off to switch the current induced inthe primary coil of the transformer T1.The 24 V DC output circuit smoothes the current induced in the secondary coil of the transformer T1 via diodes D101 andD102 and smoothing capacitors C101 and C102, and the output is controlled by the overvoltage detection circuit IC201 andthe power MOSFET Q201. For 24 V DC output, the PWM controller IC (IC1) of the switching control circuit changes the dutyof the switching pulse width of the power MOSFET Q1 via a photo coupler PC4 based on the output voltage status to adjustthe 24 V DC output.The 5 V DC output circuit smoothes the current induced in the secondary coil of the transformer T1 via diodes D101 andD102 and smoothing capacitors C101 and C102, and the output is controlled by the overvoltage detection circuit IC201 andthe power MOSFET Q201. For 5 V DC output, the PWM controller IC (IC1) of the switching control circuit changes the dutyof the switching pulse width of the power MOSFET Q1 via a photo coupler PC5 based on the output voltage status to adjustthe 5 V DC output.The overvoltage detection circuit IC201 monitors the overvoltage status of 24 V DC and 5 V DC, and when it detects anabnormal status, it gives immediately feedback to the PWM controller IC (IC1) via a photocoupler PC5 to stop controloperation and moves the power source to a standby condition.The fixing heater control circuit sends a waveform of which zero-cross is detected to the main PCB (MPCB), which controlsthe timing of HEATER REM 1 and 2 based on it to turn on the phototriacs PC1 and PC2. When the phototriacs PC1 and PC2turn on, AC current flows through the triacs TRA1 and TRA2 to turn the fixing heaters M and S on.

The operation unit PCB (OPCB) consists of the operation unit left PCB (OPCB-L) and the operation unit right PCB (OPCB-R).The operation unit right PCB (OPCB-R) consists of key switches and LEDs. The lighting of LEDs is determined by scansignals (SCAN5 to SCAN8) and LED lighting selection signals (DIGLED7 to DIGLED8) from the main PCB (MPCB). Thekey switches operated are identified by the scan signals (SCAN5 to SCAN8) and the return signals (DIGKEY4 toDIGKEY9).As an example, to light LED 1 (L1), the LED lighting selection signal (DIGLED7) should be driven low in synchronization witha low level on the scan signal (SCAN5). LEDs can be lit dynamically by repeating such operations.As another example, if KEY 1 is pressed, the corresponding key switch is turned on feeding the low level of the scan signal(SCAN5) back to the main PCB (MPCB) via the return signal (DIGKEY4). The main PCB (MPCB) locates the position wherethe line outputting the scan signal and the line inputting the return signal cross, and thereby determines which key switchwas operated.The operation unit left PCB (OPCB-L) consists of key switches and LEDs. The lighting of LEDs is determined by scansignals (SCAN1 to SCAN4) and LED lighting selection signals (DIGLED1 to DIGLED6) from the main PCB (MPCB). Thekey switches operated are identified by the scan signals (SCAN1 to SCAN4) and the return signals (DIGKEY1 toDIGKEY3).As an example, to light LED 7 (L7), the LED lighting selection signal (DIGLED1) should be driven low in synchronization witha low level on the scan signal (SCAN1). LEDs can be lit dynamically by repeating such operations.As another example, if KEY 23 is pressed, the corresponding key switch is turned on feeding the low level of the scan signal(SCAN1) back to the main PCB (MPCB) via the return signal (DIGKEY1). The main PCB (MPCB) locates the position wherethe line outputting the scan signal and the line inputting the return signal cross, and thereby determines which key switchwas operated.

Figure 2-3-8 Scanner drive PCB block diagram

The scanner drive PCB (SDPCB) consists of a stepping motor driver IC (IC1) as the center, digital transistors DT1 and DT2,etc.Drive of the scanner motor (SM) is controlled by the current setting voltage (SM Vref) that is output from the main PCB(MPCB), the mode signals (SM M1 to M5, SM CWB), the phase switchover clock signal (SM CLK), and the drive/stop signal(SM ENABLE).Also the main PCB (MPCB) outputs a control signal (EL) through a digital transistor (DT2) to the inverter PCB (INPCB) toturn on or off the exposure lamp (EL).Also the scanner drive PCB (SDPCB) acts as an interchange circuit of signals for the original detection switch (ODSW) andthe scanner home position switch (SHPSW).

Figure 2-3-10 CCD PCB block diagram

The CCD PCB (CCDPCB) is equipped with a CCD sensor IC2 for original scanning.The clock signals (CLK, RS, CLP, and SHIFT) for driving the CCD sensor (IC2) are sent as differential signals from the mainPCB (MPCB), reconstructed to normal signals by the differential receiver (IC3), and then input to the CCD sensor (IC2) viathe clock driver (IC1 and IC4).Image signals are analog signals. Even- and odd-numbered pixels are output separately. These analog image signals areamplified by emitter followers in the transistors Q1 and Q2 and then transmitted to the analog signal processing circuit in themain PCB (MPCB).

(1) Paper conveying operation in sort modeWhen a copy is made in the sort mode, the feedshift solenoid (FSSOL) turns on and the feedshift guide of the copieroperates to switch the paper path to the paper conveying unit. After curling of the conveyed paper is eliminated by the curleliminator rollers, the paper is conveyed to the intermediate tray by the feedshift roller. When the trailing edge registrationcursor of the intermediate tray shifts the paper stocked in the intermediate tray to the stopper, the pickup solenoid (PUSOL)turns on to lift the press roller and release the stopper. The stack of paper on the intermediate tray is ejected to the eject trayby the feedshift roller and eject roller.

(1) Paper switchback operationPaper of which copying is complete is conveyed to the switchback unit and sent to the switchback section by the feedshiftguide. In the switchback section, paper is conveyed by touching of the switchback press roller rotated by normal rotation ofthe switchback feed motor (SBFM), with the switchback press pulley activated by turning on the press solenoid (PRSOL).When a certain time (depending on the paper size) elapses, the switchback feed motor (SBFM) reverses the direction ofrotation to reverse the rotation of the switchback press roller to switch the direction of paper conveyance.Paper that has been switched back is conveyed to the saddle finisher by the switchback eject roller rotated by turning on theswitchback eject motor (SBEM) and the switchback eject pulley. At this time, the second paper is conveyed to theswitchback unit, the press solenoid (PRSOL) is turned off, the switchback press pulley separates from the switchback pressroller, and the first paper and the second paper are interchanged in the switchback section.(Depending on the copier model and the paper size, the press solenoid may not turn off and the switch press pulley mayalways touch the switchback press roller.)

2-1-1 Mechanical construction

The large paper deck consists mainly of the left and right cassettes and separation section. The left cassette paper feedsection sends paper from the lift to the upper and lower deck separation rollers. When the left cassette becomes empty, theright cassette paper feed section conveys paper onto the lift of the left cassette. The upper and lower deck separation rollersin the separation section convey paper received from the left cassette paper feed section into the copier, preventing multiplesheets from being fed at one time.

• Left cassette paper feedAs the paper conveying clutch (CCL) turns on, the drive is transmitted to the upper and lower deck separation rollers,starting paper feed from the left cassette. The upper and lower deck separation rollers ensure that the paper is fed one sheetat a time and that it is fed into the copier correctly.To prevent multiple sheets from being fed, there is a torque limiter on the lower deck separation roller.• When the left cassette is empty, its lift serves as a guide for the paper being conveyed from the right cassette lift.

• Raising and lowering the liftsThe following is a description of the right cassette lift operating mechanism. The left cassette lift operates in the samemanner.Paper deck motor 2 (PDM2) drives the right lift belt assembly that winches the belt up and hence raises the lift until it isstopped by deck level switch 2 (DLSW2).When paper is loaded on the lift and the deck is closed, the lift is raised until deck level switch 2 (DLSW2) turns on.When desk level switch 2 (DLSW2) is turned off as the paper on the lift is used, paper deck motor 2 (PDM2) starts to raisethe lift until the switch turns on.

• Detecting the paper levelThe lift rises as paper in the deck is used. When the remaining number of sheets in either right or left cassette reduces toaround 100 to 250 sheets, the projection on the lift belt assembly pushes against the sensor lever which turns the relevantpaper level detection sensor 1 or 2 (PLDSENS1/2) on.When both paper level detection sensors 1 and 2 (PLDSENS1, 2) have turned on, the message “Low on paper.” is shown onthe copier message display. This message is not shown when only one of them is on.As more copies are made with the message on, paper path sensors 1, 2 and 3 (PPSENS1, 2, 3) or the paper empty sensor(PESENS) start to detect absence of paper, and the message “Place paper in deck.” is shown.

Figure 2-3-2 Paper deck motor 1 drive circuit

The following is a description of the paper deck motor 1 drive circuit. Paper deck motors 1 and 2 are identical.When pin 8 of the CPU IC8 goes low, transistor Q1 is turned on causing paper deck motor 1 (PDM1) to rotate. Whentransistor Q1 is turned off, paper deck motor 1 (PDM1) stops. A brake circuit ensures the prompt stopping of the motor asfollows.When transistor Q1 turns off, transistor Q7 turns on, supplying 24 V DC to CN7-13 thereby preventing paper deck motor 1(PDM1) from rotating further under momentum.To prevent the cassette lift from being raised past its limit, an overcurrent lock detection circuit checks for the overcurrentthat would occur when paper deck motor 1 (PDM1) locks. The current from paper deck motor 1 (PDM1) into transistor Q1is converted to a voltage by resistor R46. This voltage is input to pin 5 of comparator IC7.2. If this voltage is higher than thereference at pin 4, 5 V DC is input to pin 16 of CPU IC8. If it is lower, 0 V is input to pin 16. Overcurrent of paper deck motor1 (PDM1) causes the voltage at pin 5 of IC7.2 to become higher than that at pin 4. This generates 5 V DC at pin 16 of CPUIC8, which detects overcurrent. If overcurrent lasts more than 1 s, paper deck motor 1 (PDM1) failure is determined, and pin8 of CPU IC8 outputs 5 V DC, turning paper deck motor 1 (PDM1) off.

Figure 2-3-3 Reflective photosensor (PPSENS3) circuit

The following is the operating principle of paper path sensor 3 (PPSENS3). Paper path sensors 1 and 2 (PPSENS1,PPSENS2) and the paper empty sensor (PESENS) operate in the same manner.A pulsating signal from pin 33 of the CPU IC8 turns Q9 on and off, causing the LED on the sensor PCB to flash. When theflashing LED light reflects on the paper, the phototransistor turns on and off. The on/off signal is then inverted by IC7.4 andthe paper presence signal (pulse) is input at pin 62 of the CPU IC8.If there is no paper, the phototransistor remains off and 5 V DC is input at pin 62 of the CPU IC8.

Figure 2-2-1 Fax control PCB block diagram

The fax control PCB (FCPCB) controls the overall fax operation.To transmit a fax, image data scanned by the optical section of the copier is processed by the main PCB (MPCB) and thensent to the fax control PCB (FCPCB). Received image data is first stored in the bitmap area of the SDRAM IC21 page bypage and compressed using the MH, MR or MMR method. The data is then stored in the image memory area of the SDRAMIC21 and sent to the modem LSI IC81 to be modulated from digital signal to analog signal before it is sent to the telephoneline via the NCU PCB (NCUPCB).To receive a fax, analog image data received from the telephone line via the NCU PCB (NCUPCB) is sent to the modem LSIIC81 and, after demodulation into digital signals, stored in the image memory area of the SDRAM IC21. The image data isthen decompressed and converted into the bitmap area of the SDRAM IC21 page by page and sent to the ASIC IC71 forresolution conversion and smoothing, and is passed to the main PCB (MPCB) as print image data.

The NCU PCB (NCUPCB) mainly controls the connection to the telephone line. It consists of the circuits shown in the blockdiagram.The loop current detection/tone signal reception circuit IC30 detects the DC loop current formed at the DC loop/dial pulsetransmission circuit PC80 to determine the status of the telephone line. It also receives tone (DTMF) signals during remotecontrol. The ring signal detection circuit PC60 detects the ring signals from the telephone line to determine call reception.The DC loop/dial pulse transmission circuit PC80 turns on and off the DC loop formed in the telephone line to send out dialpulses (selection signals). The external telephone off-hook detection circuit (T40 and PC40) detects the off-hook state of thetelephone connected or the handset*1. The destination identification circuit (JP20, JP21 and JP22) is used by the fax controlPCB (FCPCB) to identify the destination of the NCU PCB (NCUPCB). The accounting pulse elimination circuit L70 removessignals representing the communication charge information (accounting pulses) before they reach the modem whentelephone line is used.*2 This is because accounting pulses obstruct fax communications. The ground start circuit PC10requests an outside connection to the private branch exchange (PBX) when calling via the PBX.*2

The auxiliary power source PCB (APSPCB) is a switching regulator that converts an AC input to generate 5.2 V DC and 12V DC. It consists of a switching control circuit, 5.2 V DC output circuit and 12 V DC output circuit.The rectifier circuit rectifies the full-wave of the AC input using the diode bridge D2. The smoothing capacitor C7 smoothesout the pulsed current from the diode bridge.The switching control circuit turns on/off the power MOSFET Q2 with the voltage induced in the controlling coil of thetransformer T1 to switch the current induced in the primary coil of the transformer T1.The 5.2 V DC output circuit smoothes out the voltage from the current induced in the secondary coil of the transformer T1 viathe diode D5 and smoothing capacitors C15 and C91, and outputs a stable 5.2 V DC using the shunt regulator IC1. Theoutput status of the 5.2 V DC is fed back to the switching control circuit via the photo-coupler PC1. Based on the feedback,the switching control circuit changes the duty cycle of the pulse that turns power MOSFET Q2 on/off in order to adjust the5.2 V DC.The 12 V DC output circuit smoothes out voltage from the current induced in the secondary coil of the transformer T1 via thediode D6 and smoothing capacitor C19, and generates a stable 12 V DC using the 3-pin regulator IC2.The relay turns on/off the AC supply to the power source PCB (PSPCB) based on the remote signal from the fax controlPCB (FCPCB).

Caution:• Turn the main power switch off and disconnect the power plug from the wall outlet before disconnecting or inserting

connectors.• When writing data to Compact Flash card from a computer, be sure to format it in advance.

(For formatting, insert a Compact Flash card and select a drive.)• For a desktop computer, connect a Compact Flash card reader/writer to it. For a notebook computer, use a PC card

adapter or a connection portion only for Compact Flash card.

<Procedure>1. Check the current ROM version using maintenance

item U680.2. Turn the main switch off and disconnect the power

plug from the wall outlet.3. Remove the rear cover and the control-box cover.

(Refer to “(1) Updating the firmware on the faxcontrol PCB (Flash ROM)”, Steps 1 to 3, above.)

4. Insert a Compact Flash card containing the bootprogram into the CF jig. Be sure that the card fits insmoothly along the left and right guides. (Trying toforce the card in incorrectly may cause electricalcontacts to break.)

5. Set dip-switch bit SW012 on the jig to “BOOT”.

6. Connect CN1 on the CF jig to YC5 on the fax control PCB.

7. Plug the power plug back into the wall outlet, and turn the main switch on.ROM upgrading begins automatically. The LED on the CF jig flashes while upgrading is in progress (for about 2min.), then comes on solid to indicate that upgrading is finished.

8. Turn the main switch off, and disconnect the power plug from the wall outlet.9. Disconnect the CF jig from the fax control PCB.

Figure 2-2-1 Fax control PCB block diagram

The fax control PCB (FCPCB) controls the overall fax operation.To transmit a fax, image data scanned by the optical section of the copier is processed by the main PCB (MPCB) and thensent to the fax control PCB (FCPCB). Received image data is first stored in the bitmap area of the SDRAM U21/U22 pageby page and compressed using the MH, MR, MMR or JBIG method. The data is then stored in the image memory area ofthe SDRAM U21/U22 and sent to the modem LSI U81 to be modulated from digital signal to analog signal before it is sentto the telephone line via the NCU PCB (NCUPCB).To receive a fax, analog image data received from the telephone line via the NCU PCB (NCUPCB) is sent to the modem LSIU81 and, after demodulation into digital signals, stored in the image memory area of the SDRAM U21/U22. The image datais then decompressed and converted into the bitmap area of the SDRAM U21/U22 page by page and sent to the ASIC U71for resolution conversion and smoothing, and is passed to the main PCB (MPCB) as print image data.

The NCU PCB (NCUPCB) mainly controls the connection to the telephone line. It consists of the circuits shown in the blockdiagram.The loop current detection/tone signal reception circuit IC30 detects the DC loop current formed at the DC loop/dial pulsetransmission circuit PC80 to determine the status of the telephone line. It also receives tone (DTMF) signals during remotecontrol. The ring signal detection circuit PC60 detects the ring signals from the telephone line to determine call reception.The DC loop/dial pulse transmission circuit PC80 turns on and off the DC loop formed in the telephone line to send out dialpulses (selection signals). The external telephone off-hook detection circuit (T40 and PC40) detects the off-hook state of thetelephone connected. The destination identification circuit (JP20, JP21 and JP22) is used by the fax control PCB (FCPCB)to identify the destination of the NCU PCB (NCUPCB). The accounting pulse elimination circuit L70 removes signalsrepresenting the communication charge information (accounting pulses) before they reach the modem when telephone lineis used.* This is because accounting pulses obstruct fax communications. The ground start circuit PC10 requests anoutside connection to the private branch exchange (PBX) when calling via the PBX.*

*For 220 - 240 V specifications only.

Figure 2-2-5 Auxiliary power source PCB block diagram

The auxiliary power source PCB (APSPCB) is a switching regulator that converts an AC input to generate 5.2 V DC and 12V DC. It consists of a switching control circuit, 5.2 V DC output circuit and 12 V DC output circuit.The rectifier circuit rectifies the full-wave of the AC input using the diode bridge D2. The smoothing capacitor C7 smoothesout the pulsed current from the diode bridge.The switching control circuit turns on/off the power MOSFET Q2 with the voltage induced in the controlling coil of thetransformer T1 to switch the current induced in the primary coil of the transformer T1.The 5.2 V DC output circuit smoothes out the voltage from the current induced in the secondary coil of the transformer T1via the diode D5 and smoothing capacitors C15 and C91, and outputs a stable 5.2 V DC using the shunt regulator IC1. Theoutput status of the 5.2 V DC is fed back to the switching control circuit via the photo-coupler PC1. Based on the feedback,the switching control circuit changes the duty cycle of the pulse that turns power MOSFET Q2 on/off in order to adjust the5.2 V DC.The 12 V DC output circuit smoothes out voltage from the current induced in the secondary coil of the transformer T1 via thediode D6 and smoothing capacitor C19, and generates a stable 12 V DC using the 3-pin regulator IC2.The relay turns on/off the AC supply to the power source PCB (PSPCB) based on the remote signal from the fax controlPCB (FCPCB).
