1. Installation Precautions
WARNING
• Do not use a power supply with a voltage other than that specified.Avoid multiple connections to one outlet: they may cause fire or electricshock. When using an extension cable, always check that it isadequate for the rated current. ...............................................................
• Connect the ground wire to a suitable grounding point. Not groundingthe copier may cause fire or electric shock. Connecting the earth wireto an object not approved for the purpose may cause explosion orelectric shock. Never connect the ground cable to any of the following:gas pipes, lightning rods, ground cables for telephone lines and waterpipes or faucets not approved by the proper authorities. ........................
CAUTION:
• Do not place the copier on an infirm or angled surface: the copier maytip over, causing injury. ...........................................................................
• Do not install the copier in a humid or dusty place. This may cause fireor electric shock. .....................................................................................
• Do not install the copier near a radiator, heater, other heat source ornear flammable material. This may cause fire. .......................................
• Allow sufficient space around the copier to allow the ventilation grills tokeep the machine as cool as possible. Insufficient ventilation maycause 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 may cause the copier to move unexpectedly ortopple, leading to injury. ..........................................................................
• Avoid inhaling toner or developer excessively. Protect the eyes. If toneror developer is accidentally ingested, drink a lot of water to dilute it inthe stomach and obtain medical attention immediately. If it gets into theeyes, rinse immediately with copious amounts of water and obtainmedical attention. ....................................................................................
• Advice customers that they must always follow the safety warnings andprecautions in the copier’s instruction handbook. ...................................
2. Precautions for Maintenance
WARNING
• Always remove the power plug from the wall outlet before startingmachine disassembly. ............................................................................
• Always follow the procedures for maintenance described in the servicemanual and other related brochures. ......................................................
• Under no circumstances attempt to bypass or disable safety featuresincluding safety mechanisms and protective circuits. .............................
• Always use parts having the correct specifications. ...............................
• Always use the thermostat or thermal fuse specified in the servicemanual or other related brochure when replacing them. Using a pieceof wire, for example, could lead to fire or other serious accident. ...........
• When the service manual or other serious brochure specifies adistance or gap for installation of a part, always use the correct scaleand measure carefully. ...........................................................................
• Always check that the copier is correctly connected to an outlet with aground connection. .................................................................................
• Check that the power cable covering is free of damage. Check that thepower plug is dust-free. If it is dirty, clean it to remove the risk of fire orelectric shock. .........................................................................................
• Never attempt to disassemble the optical unit in machines using lasers.Leaking laser light may damage eyesight. ..............................................
• Handle the charger sections with care. They are charged to highpotentials and may cause electric shock if handled improperly. .............
CAUTION
• Wear safe clothing. If wearing loose clothing or accessories such asties, make sure they are safely secured so they will not be caught inrotating sections. .....................................................................................
• Use utmost caution when working on a powered machine. Keep awayfrom chains and belts. .............................................................................
• Handle the fixing section with care to avoid burns as it can beextremely hot. .........................................................................................
• Check that the fixing unit thermistor, heat and press rollers are clean.Dirt on them can cause abnormally high temperatures. .........................
• Do not remove the ozone filter, if any, from the copier except forroutine replacement. ...............................................................................
• Do not pull on the AC power cord or connector wires on high-voltagecomponents when removing them; always hold the plug itself. ..............
• Do not route the power cable where it may be stood on or trapped. Ifnecessary, protect it with a cable cover or other appropriate item. ........
• Treat the ends of the wire carefully when installing a new charger wireto avoid electric leaks. ............................................................................
• Remove toner completely from electronic components. .........................
• Run wire harnesses carefully so that wires will not be trapped ordamaged. ................................................................................................
• After maintenance, always check that all the parts, screws, connectorsand wires that were removed, have been refitted correctly. Specialattention should be paid to any forgotten connector, trapped wire andmissing screws. ......................................................................................
• Check that all the caution labels that should be present on the machineaccording to the instruction handbook are clean and not peeling.Replace with new ones if necessary. ......................................................
• Handle greases and solvents with care by following the instructionsbelow: .....................................................................................................· Use only a small amount of solvent at a time, being careful not to
spill. Wipe spills off completely.· Ventilate the room well while using grease or solvents.· Allow applied solvents to evaporate completely before refitting the
covers or turning the main switch on.· Always wash hands afterwards.
• Never dispose of toner or toner bottles in fire. Toner may causesparks when exposed directly to fire in a furnace, etc. .........................
• Should smoke be seen coming from the copier, remove the powerplug from the wall outlet immediately. ..................................................
3. Miscellaneous
WARNING
• Never attempt to heat the drum or expose it to any organic solventssuch as alcohol, other than the specified refiner; it may generate toxicgas. .........................................................................................................

Each drawer consists of a lift driven by the lift motor and other components. Eachdrawer can hold up to 550 sheets of paper.Paper is fed from the drawer by the rotation of the forwarding pulley and upper paperfeed pulley. The lower paper feed pulley prevents multiple sheets from being fed at onetime, via the torque limiter.

The bypass table can hold up to 100 sheets of paper at one time.When the start key is pressed, the bypass solenoid (BYPSOL) turns on, unlocking thebypass stopper and lowering the bypass forwarding pulley until it comes into contactwith the paper. This conveys paper placed on the bypass table to the bypass upper andlower paper feed pulleys. The bypass paper feed clutch (BYPPFCL) then turns on,transmitting the drive motor (DM) drive to these pulleys to start primary paper feed.The bypass lower paper feed pulley rotates opposite to the paper feed direction so thatthe torque limiter prevents multiple sheets from being fed at one time.

Formation of magnetic brush
The developing roller consists of a magnet roller with five poles and a sleeve roller.Rotation of the sleeve roller around the magnet roller entrains developer, which in turnforms a magnetic brush at pole N1 on the magnet roller. The height of the magnet brushis regulated by the doctor blade; the developing result is affected by the position of thepoles on the magnet roller and the position of the doctor blade.A developing bias voltage generated by the high-voltage transformer (HVTPCB) isapplied to the developing roller to provide image contrast.

Toner density is detected by the toner sensor (TNS).The sensor section of the toner sensor detects the ratio of toner to carrier in thedeveloper near it and converts it into a voltage. As more toner is used, the ratio of tonerto carrier decreases, increasing the toner sensor output voltage.When the ratio drops below the specified value, the increase in toner sensor outputvoltage triggers toner replenishing. When toner is added and the ratio of toner to carrierreturns to normal, the toner sensor output voltage drops to the point where tonerreplenishing stops.

Toner density control
Toner density control is conducted using the TARGET value as the reference which isthe toner sensor initial output value set by maintenance item U130 when developer isloaded for the first time.

Computing the absolute humidityThe external humidity sensor (EHUMSENS) and external temperature thermistor(ETTH) are located on the humidity sensor PCB (HUMPCB). The external humiditysensor (EHUMSENS) converts the relative humidity detected by the humidity sensingelement into a voltage and sends it to the engine PCB (EPCB). The main PCB(MPCB)computes the absolute humidity based on this EHUMSENS signal and thetemperature (ETTH signal) detected by the external temperature thermistor (ETTH).

Toner level detection
The toner level in the toner main hopper is monitored by the toner level detection sensor(TLDS). It converts the presence or absence of toner in the toner main hopper into avoltage and sends it to the main PCB (MPCB), which triggers a message to request thetoner cartridge to be replaced before the recycled toner ratio in the toner main hopperreaches a significant level.

Toner hopper lockup detection
The amount of recycled toner in the toner main hopper is monitored by the toner hopperlockup sensor (TLS). It converts the presence or absence of toner in the toner mainhopper into a voltage and sends it to the main PCB, which prevents toner main hopperlockup as the amount of the recycled toner in the hopper increases.

The transfer and separation section consists of the transfer charger assembly and drumseparation claws.The transfer charger assembly consists of the transfer charger that applies a highvoltage to transfer the toner image from the drum surface onto the paper, and theseparation charger that helps the paper separate from the drum surface.In the transfer charger, a high voltage generated by the high-voltage transformer PCB(HVTPCB) is applied to the both ends of the tungsten wire.The separation charger uses the AC voltage applied from the high-voltage transformerPCB to neutralize the residual charge on the paper after the transfer process. The papercan then separate from the drum under its own weight.The separation claws ensure that the paper separates reliably from the drum.

(12) Large paper deck
The large paper deck consists mainly of the right and left cassettes and separationsection. The right cassette primary paper feed section sends paper from the lift to theupper and lower deck separation rollers. When the right cassette becomes empty, theleft cassette primary paper feed section conveys paper onto the lift of the right cassette.The upper and lower deck separation rollers in the separation section convey paperreceived from the right cassette primary paper feed section into the copier, preventingmultiple sheets from being fed at one time.

(12-3) Raising and lowering the liftsThe following is a description of the right cassette lift operating mechanism. The leftcassette lift operates in the same manner.Paper deck motor 1 (PDM1) drives the right lift belt assembly that winches the belt upand hence raises the lift until it is stopped by deck level switch 1 (DLSW1).When paper is loaded on the lift and the deck is closed, the lift is raised until deck levelswitch 1 (DLSW1) turns on.When desk level switch 1 (DLSW1) is turned off as the paper on the lift is used, paperdeck motor 1 (PDM1) starts to raise the lift until the switch turns on.

When the deck is opened for removing a jammed paper or other purposes, the winchshaft is released from its holder on paper deck motor 1 (PDM1), allowing the lift todescend under its own weight. The air damper buffers the impact of the descending lift.

(12-4) Detecting the paper levelThe lift rises as paper in the deck is used. When the remaining number of sheets ineither right or left cassette reduces to around 100 to 250 sheets, the projection on the liftbelt assembly pushes against the sensor lever which turns the relevant paper leveldetection sensor 1 or 2 (PLDSENS1/2) on.When both paper level detection sensors 1 and 2 (PLDSENS1, 2) have turned on, themessage “Low on paper.” is shown on the copier touch panel. This message is notshown 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 ofpaper, and the message on the copier touch panel changes to “Place paper in deck.”

2-3-2
The power source PCB (PSPCB) is a switching regulator which converts an AC input togenerate 24 V DC, 5.1 V DC and 12 V DC. It consists of the components shown inFigure 2-3-1; noise filter circuit, rectifier circuit, power factor improvement control circuit,switching control circuit, 24 V DC output circuit, 5.1 V DC output circuit, 12 V DC outputcircuit, fixing heater control circuit, cooling fan control circuit, overheat detection circuit,overvoltage detection circuit, overcurrent detection circuit.The noise filter circuits, consisting mainly of the noise filter circuit in the power sourcesection and capacitors, attenuates external noise and prevents switching noisegenerated by the power source circuit and the heater control circuit from leaving themachine via the AC line.The rectifier circuit full-wave rectifies the AC input which has passed through the noisefilter using the diode bridge D001. In the power factor improvement control circuit, aboosting converter, the controller IC1 turns FETs Q101 and Q102 on and off at highfrequency so that the waveform of the input current becomes analogous with thewaveform of the constantly-monitored input voltage. It then restores this by imitating theinput voltage waveform to improve the wave form of the input current (which usuallylooks like pulses) into sine waves. Choke coil L101 and diodes D107 and D108 are partof the boosting converter.The switching control circuit turns the FETs Q103 and Q104 on and off via the PWMcontroller IC2 to apply the AC component from the DC voltage smoothed via theelectrolytic capacitor C101 to the primary coil of the transformer T1.The 24 V DC output circuit smoothes the current induced on the secondary coil of thetransformer T1 via diodes D201, D202 and D203, and outputs a more stable 24 V DCby the function of shunt regulator IC3. The output status of 24 V DC is fed back to thePWM control IC2 in the switching control circuit via the photocoupler PC1, and based onthe feedback, the PWM control IC2 outputs stable 24 V DC constantly by controlling theswitching duty pulse width for the FETs Q103 and Q 104.The 5.1 V DC output control circuits IC4 and IC5 receive 24 V DC from the 24 V DCoutput circuit and output stable 5.1 V DC by the function of the DC/DC converter controlIC4 and IC5.The 12 V DC output circuit receive 24 V DC from the 24 V DC output circuit and outputsstable 12 V DC by the function of a power supply regulator.The cooling fan control circuit IC7 monitors the temperature of heating elements on theprimary side, and activates the cooling fan if the temperature reaches thepredetermined level for forced air-cooling of the heating elements.In the energy saving mode, FET Q201 conducts when it receives a sleep signal fromthe main PCB (MPCB), thus cutting off the output of 24 V DC. Since input to the 12 VDC control circuit IC6 is also cut off, output of 12 V DC also ceases. The 5.1 V DCoutput circuit IC4 also stops the control circuit IC5 and output of 5.1 V DC when itreceives a sleep signal.As a result, all outputs except the sub-output from the 5.1 V DC output circuit IC5 arecut off, by which means energy consumption is lowered to the Energy Star accreditationlevel while in the stand-by mode.Abnormal rise of voltage for all DC outputs and overcurrent in all outputs except the 24V DC and 12 V DC outputs are monitored by the overvoltage and overcurrent detectioncircuits, and if any abnormal rise is detected, alarm signals are fed back to the PWMcontrol circuit IC2 on the primary side via photocoupler PC2, by which means powersupply is shut down. Overload of the 24 V DC output is monitored by resistors R117 andR118 as the total sum of current on the primary side, and if any abnormal condition isdetected, the operation of the PWM control circuit IC2 stops and the power supply is
2AD

shut down.Overload of the 12 V DC output circuit is controlled by the overcurrent protectionfunction of power source regulator IC7. When the abnormal output condition isremoved, the 12 V DC output returns to the normal output condition.The fixing heater control circuit sends zero-crossing signal (Z CROSS SIG) via thephotocoupler PC3 to the main PCB (MPCB). These signals are in turn converted intosignals to control the on/off timing and phases, which are then input to the power sourcePCB (PSPCB) as the H1 REM and H2 REM signals. The phototriacs PT1 and PT2 areturned on by the H1 REM and H2 REM signals, and electricity flows through triacs TR2and TR3 to turn the fixing heaters on.

The following is a description of memory copy PCB 1 (MCPCB1). Memory copy PCB 2(MCPCB2) is identical to memory copy PCB 1 (MCPCB1).Memory copy PCB 1 (MCPCB1) consists of CPU U17, ASIC U16, SRAMs U4 and U11,DRAMs U13, U14, U15, U18, U19 and U20, EPROM U1, and CODECs U25 and U26.The memory copy PCB mainly serves to read images from the scanner based on thecontrol signals from the main PCB (MPCB), and output the images to the engine (thecomponent where printing to paper and driving of mechanisms are executed). It alsoperforms editing operations such as image rotation, image summary and imagesynthesizing.Since the original scanning speed of the scanner and the printing speed of the engine(the component where printing to paper and driving of mechanisms are executed) aredifferent, and their operations not synchronized, memory copy PCB 1 (MCPCB1) alsoserves as a buffer to deal with the speed and timing differences between them.

Selection of key switches and the lighting of LEDs are determined by scan signals(SCAN L1 - L3) and LED signal selection signals (DIGLED L1 - L4). The key switchoperated is identified by the scan signals (SCAN L1 - L3) and the return signals(DIGKEY L1 - L3).As an example, to light LED 1, the LED lighting selection signal (DIGLED L1) should bedriven low in synchronization with a low level on the scan signal (SCAN L1). TransistorTR1 conducts and LED1 is lit. LEDs can be lit dynamically by repeating suchoperations.As an example, if KEY1 is pressed, the corresponding key switch is turned on feedingthe low level of the scan signal back to the operation unit main PCB (OMPCB) via thereturn signal (DIGKEY L1). The operation unit main PCB (OMPCB) locates the positionwhere the line outputting the scan signal and the line inputting the return signal cross,and thereby determines which key switch was operated.

Figure 2-3-13 Paper deck motor 1 drive circuit
The following is a description of the paper deck motor 1 drive circuit. Paper deck motors1 and 2 are identical.When pin 14 of the CPU IC7 goes low, transistor Q1 is turned on causing paper deckmotor 1 (PDM1) to rotate. When transistor Q1 is turned off, paper deck motor 1 (PDM1)stops. A brake circuit ensures the prompt stopping of the motor. When transistor Q1turns off, transistor Q3 turns on, supplying 24 V DC to CN7-1 thereby preventing paperdeck motor 1 (PDM1) from rotating further under momentum.When the right cassette lift is raised past the limit, upper limit switch 1 (UPSW1) turnson, taking the level at pin 58 of the CPU IC7 low, which turns transistor Q1 and hencepaper deck motor 1 (PDM1) off. This level change is also passed to pin 9 of a protectivecircuit consisting of IC8.3, forcing paper deck motor 1 (PDM1) off directly in case theCPU IC7 fails.

IC1 monitors the supply voltage and also determines if the CPU IC7 is operatingcorrectly. If the supply voltage VCC drops below VSL (approx. 4.2 V DC), the reset signal(RES) is output to the CPU IC7 (A in the timing chart).IC1 monitors the clock signal (CK) from pin 50 of the CPU IC7 which goes lowperiodically. If the CPU IC7 fails, IC1 detects that the clock signal (CK) has stopped andsends a reset signal (RES) to the CPU IC7 (B in the timing chart). To reset the CPUIC7, pin 8 (RES) of IC1, which usually outputs 5 V DC, goes low and takes the level atpin 7 of the CPU IC7 low.

3 Press the print key. Operation starts.
Scanning is performed under the selected conditions and the result isdisplayed.
When scanning is performed before shading, the scan value at themachine center should be slightly different from those at the machinefront and rear. When scanning is performed after shading, there shouldbe no difference between respective values. Any differences betweenthe values at machine front and rear indicates that scanner problemcauses the fixing unevenness.
If the displayed results indicate no shading problems, the fixingunevenness (uneven copy density) is caused by factors other than inthe scanner section (shading or CCD).
If a black line appears, the cause may assumed to be based on theresults of the scanning operation before shading: if a white lineappears, they may be assumed based on the results of the scanningoperation after shading. Note that depending on the thickness andlocation of the black or white line, it may not be possible to use thismethod to determine the cause. This is because the displayed valuesobtained from scanning at the limit of nine points are insufficient toprovide significant information.
