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. .........................................................................................................

1-2-1 Handling and storage of the drumUse the following caution when handling the drum.• When removing the drum from the main unit, make sure not to expose it to direct sunshine
or strong lighting.• Store the drum where the ambient temperature is kept between –20°C/–4°F and 40°C/
104°F and humidity around 85%RH. Sudden changes in temperature and humidity evenwithin the permitted ranges should be avoided, too.
• Avoid atmosphere laden with substances that might chemically damage the drum surface.• Never hit the drum surface with anything hard or pointed. Protect it from bare or gloved
hands; if it is accidentally touched, clean by following the proper procedure.
1-2-2 Storage of developer and tonerStore developer and toner in a cool, dark place free from direct sunshine or high humidity.
1-2-3 Handling of the heatersThis copier is equipped with heaters to avoid condensation inside. These heaters are keptpowered as long as the copier power cable is connected to a wall outlet with the main switchset off. Never disconnect the power cable if the copier is used in a humid place of 70%RHhigher.If the copier is not going to be used for long periods of time, disconnect the power cable fromthe wall outlet.Each roll unit of this copier is equipped with a roll unit heater*1 which can be individuallyturned on or off with a switch. If normal plain paper is kept in the roll units and there is a riskof high humidity, keep their heaters on. However, keep the heater off if tracing paper is keptin the roll unit.
1-2-4 Storage of paperPaper should be stored in a cool, dark place free from high temperature or humidity. If it isnot going to be used for a long time, take paper out of the roll unit, put it in the originalwrapping paper and seal.

(3) Exposure and original feed section
Figure 1-3-15 Exposure and original feed section
Exposure is accomplished by scan exposure method with a moving original. A fluorescentlamp is used as the light source. While being conveyed across the contact glass by therollers, the original is exposed by the fluorescent light and the exposed image is read by theCIS (contact image sensor).The fluorescent lamp heater (FLH) is installed on the fluorescent lamp (FL) to improve thetemperature characteristics which maintains the temperature of the fluorescent lamp toapproximately 40°C/104°F. The CIS reads the reflection of the fluorescent lamp (FL) lighton the middle upper original roller (white reference) to maintain the intensity constant.The original is fed by the rotation of the front/middle/rear upper original rollers and the front/rear lower original rollers. These rollers are controlled by the original leading edge detectionswitch (OLDSW), the original trailing edge detection switch (OTDSW), and the original feedclutch (OFCL). The original feed motor (OFM) drives the exposure section.

CIS correction
• Shading correctionShading correction is carried out to correct the fluctuation in the fluorescent lamp (FL)intensity and variations in the sensitivity between the sensor elements constituting the CIS.If shading correction does not end within 30 s from its start, an original jam (J-05) isindicated. If shading correction fails to end six times successively after the original isreinserted, service call code C-300 is triggered.

With the fluorescent lamp lit, the aver- age of the sensor read-in data on the middle upper original roller (white reference) is calculated for each channel (see Figure 1-3-21).
The CIS read-in data is corrected based on the black and white reference values while the original image is read in.

• AGC processing (gray level correction)The tone of the image is reproduced by dividing the CIS image read-in value into 256 levels.If the absolute white level is assumed to be 5.0 V and the absolute black level 0 V, the rangeof the actual image read-in value is narrower than the range from 0 to 5.0 V, so the tone ofthe reproduced image is affected. AGC processing (auto gain control) corrects the imageread-in value to reproduce gray levels more accurately.
Figure 1-3-22 AGC processing
Example: If the maximum white reference value (AGCHMAX) read by the CIS is 4.0 V andthe minimum black reference value (AGCLMIN) is 0.8 V, the range of the imageread-in value is narrower than the range between the absolute white level (5.0V) and absolute black level (0 V). In such a case, the read-in value cannot bedivided into 256 levels and the tone of the reproduced image is affected. AGCprocess corrects VREFH to 4.0 V, VREFL to 0.8 V and the correction value to 0so that the read-in value can be divided into 256 levels to reproduce the tone ofthe image more correctly.
• γ (gamma) correctionThere are slight differences in the black-level read-in values between the four channels ofthe CIS. Gamma correction can be made by executing simulation 120 so that an even imageoutput level is obtained.

Forming the magnetic brush
The developer flows by the rotation of the developing roller and the magnetic brush is formedon pole N1. The height of the magnetic brush is set by the gap between the doctor bladeand the developing roller. The developing bias voltage (650 V DC) which is output from thedeveloping bias high-voltage transformer (DBHVT) is applied to the developing roller toimprove the image contrast. When the drum surface potential reaches 0 V after completionof copying, the developing bias voltage is switched to –100 V DC to prevent toner and carrierfrom adhering to the drum.

Temperature compensation of the toner sensor output
Temperature compensation of the toner sensor (TNS) output value is applied by thefollowing formula.The output values from the toner sensor (TNS) and the developing unit thermistor (DTH)are input to the main PCB (MPCB). The main PCB samples the two input values at 8 msintervals. If two of three successive sampled input values are the same, this value is usedas one input value.
X = TS – K (TH – D26)where X: control input (V, toner sensor output value after temperature compensation)
TS: actual toner sensor output (V)K: temperature compensation coefficient (0.005 V/deg: TH > 26°C/79°F,
0.014 V/deg: TH < 26°C/79°F)TH: temperature of the developing unit (°C/°F, detected temperature of the
developing unit thermistor)D26: reference temperature (26°C/79°F)
A change in temperature TH – D26 based on the reference temperature (26°C/79°F) ismultiplied by temperature compensation coefficient K to obtain the temperature compensationvalue; this is then subtracted from actual toner sensor output TS. Because the rate ofincrease in the toner sensor output value is high when the temperature of the developingunit is greater than 26°C/79°F, the main PCB compensates the toner sensor outputfollowing the above formula, so as to lower the output. Because the rate of decrease in thetoner sensor output value is high when the temperature of the developing unit is less than26°C/79°F, the main PCB compensates to increase the output.

Toner sensor output correction based on the copy count
The toner sensor (TNS) output is corrected by the following formula based on the copy count(copy distance).
X = KM + TSwhere X: control input value (V, toner sensor output value after copy count correction)
M: copy distance after execution of simulation 60 (m)TS: actual toner sensor output (V)
K: distance correction coefficient (0.00021 V/m)
Figure 1-3-26
A The copy distance count is cleared during developer setting (simulation 60).B Until the copy distance reaches 1000 m, the actual toner sensor output value is corrected
by the formula as the copy distance increases.C When the copy distance exceeds 1000 m, the actual toner sensor output value is
corrected with a constant value of +0.21 V.

Toner density control
Figure 1-3-27 Toner density control
A The value set while simulation 60 (developer setting) is performed is used as the tonercontrol level (initial output value for the toner control sensor). Toner feed motor (TM) on/off control is based on this reference value.If the temperature- and count-corrected toner sensor output value exceeds the tonercontrol level, the toner feed motor is turned on for 0.5 s to supply toner from the tonerhopper to the developing unit assembly. (The toner feed motor can be turned on onlywhen the developing unit assembly is driven, i.e. the drive motor is on.)If the toner sensor output value does not drop during this 0.5 s period, the toner feedmotor is turned on for another 0.5 s, and this operation is repeated until the toner sensoroutput value becomes lower than the toner control level.
B If the toner sensor output value rises further and remains 0.234 V or more above the tonercontrol level for 10 s, the toner empty level is detected and toner feed aging operationis carried out. When the toner sensor output value reaches the toner control level, agingis performed for 3 minutes after toner replenishing ends (toner feed motor off). If thetoner sensor output value does not reach the toner control level after 3 minutes of tonerfeed aging, toner empty condition is detected and the add toner indicator on theoperation panel lights.
C When the toner sensor output value is 0.351 V or more above the toner empty level, thetoner empty high level is detected and the message requesting toner to be replenishedis shown on the display, inhibiting copying.
D When toner is replenished to the toner hopper and the toner sensor output value reachesthe toner control level, aging is performed for 3 minutes and then copying is enabled.

(7) Cleaning sectionCleaning is performed by the blade cleaning method and the cleaning fur brush. Thecleaning section is comprised of the cleaning blade and the cleaning fur brush which removethe residual toner adhering to the drum after transfer, and the cleaning unit spiral whichcollects and sends toner to the waste toner tank.The cleaning fur brush rotates always in contact with the drum surface and prevents thetoner scraped off the drum by the cleaning blade from dropping inside of the machine. Otherforeign matter such as paper fragments adhering to the surface of the drum are alsoremoved by the brush.When the waste toner tank becomes full, the overflow sensor (OFS) is turned off and amessage requesting the waste toner tank to be checked appears on the display on theoperation panel, and copying is inhibited.

The fixing section is comprised of the parts shown in Figure 1-3-35. After the transferoperation, the paper is conveyed to the fixing section and passes between the heat rollerand the press roller. A constant pressure is applied between the heat roller and the pressroller by the fixing press spring and the toner transferred is fixed on the paper by the heatand pressure applied from each roller.Fixing heater M (H1) heats the center of the heat roller and fixing heater S (H2) heats theends of the heat roller.The oil roller cleans the surface of the heat roller to prevent the paper from wrapping aroundthe heat roller.After fixing, the paper is separated from the heat roller by the separation claws and ejectedto outside of the machine via the eject roller and the eject pulley.

Heating and temperature control of heat roller and press roller
• Heat roller temperature control 1Fixing unit thermistor 1 (FTH1) detects the surface temperature around the center of theheat roller and fixing unit thermistor 2 (FTH2) detects the surface temperature of the rightend of the heat roller.If the temperature TPRD (surface temperature around the center of the press roller) detectedby fixing unit thermistor 3 (FTH3) becomes less than TPTH, fixing heaters M and S (H1 andH2) are turned on to heat the heat roller. Control temperature T is controlled by the followingformula.
Control temperature T = THCON + k (TPTH – TPRD)When (TPTH – TPRD) < 0, T = THCON.
THCON: heat roller control temperaturek: temperature compensation coefficient (standby: 0.33, copying: 1)

• Press roller temperature control 1If the surface temperature of the press roller is less than its minimum value or the surfacetemperature between the heat roller side and on the opposite side is different, fixingproblems may occur. Therefore, the following control is performed to keep the surfacetemperature of the press roller constant.In ready status, if the fixing unit thermistor 3 (FTH3) temperature (temperature around thecenter of the press roller) becomes less than 80°C/176°F, fixing heaters M and S (H1 andH2) are turned on. The fixing drive motor (FDM) is then turned on at low speed to increasethe surface temperature of the press roller. When the temperature of fixing unit thermistor3 (FTH3) reaches 90°C/194°F, fixing heaters M and S (H1 and H2) and the fixing drive motor(FDM) are turned off. By repeating these operations, the surface temperature of the pressroller is maintained between 80°C/176°F and 90°C/194°F.
• Press roller temperature control 2When copies are made with small-size paper, the press roller temperature becomes higherat the ends where no paper passes than around the center where paper passes. Thiscauses the ends of the press roller to swell, reducing the paper conveying force around thecenter.After copying is completed, the fixing unit thermistor 3 (FTH3) temperature (temperaturearound the center of the press roller) is compared to the fixing unit thermistor 4 (FTH4)temperature (temperature at the right end of the press roller), and the fixing drive motor(FDM) speed is corrected in proportion to the temperature difference to prevent the paperconveying speed from decreasing in the fixing unit.

Figure 2-3-4 Pulse width control circuit
In the pulse width control circuit, FETs Q3 and Q4 are switched on and off by the pulsesignals from the pulse width control IC U2. The current flowing into the primary side coil oftransformer T from the smoothing circuit is switched, and an e.m.f. is generated in thesecondary coil. U2 changes the duty ratio for the pulse signals switching the FETs on andoff to control the voltage output to the secondary side.When the secondary side output voltage becomes too large, shunt regulator Z6 in the errordetection circuit of the 24 V DC output circuit conducts and photocoupler Z9 turns on. Thesignal from this photocoupler is fed back to U2 which reduces the duty cycle of the pulsesignals, so reducing the output voltage.

In the 24 V DC output circuit, the voltage generated in the secondary coil of the transformeris rectified by diodes D12 and D13, smoothed by choke coils L10 and L11 and capacitorsC38 and C39, and is output as 24 V DC.The CR elements of the rectification circuit (C27, C28, R46, C29, C30, R47) and (R48, C31,C32, R49, C33, C34) form a CR snapper circuit and absorb a rectification voltage surge.Chokes L6, L7, L8 and L9 connected in series with the diodes form a magnetic spanner andabsorb a rectification current surge. These components reduce the high-frequencyrectification noise.In the error detection circuit, a voltage fluctuation in the 24 V DC output is detected by shuntregulator Z6 and the voltage fluctuation is isolated with photocoupler Z9 and fed back to U2of the pulse width control circuit.

Figure 2-3-6 5 V DC output/5 V DC over-current protection circuit
The 5 V DC output circuit reduces the smoothed 24 V DC from the 24 V DC output circuitto 5 V DC.The current for the output from the 24 V DC output circuit is stabilized by choke coil L13 andsmoothing capacitors C37 and C40, and is fed to the 5 V DC output circuit. In the 5 V DCoutput circuit, FET Q5 is switched on and off by switching regulator IC U3 so that the outputvoltage becomes 5 V DC. This output voltage is smoothed by choke coil L15 and smoothingcapacitor C43 and is output. U3 also monitors the voltage drop generated across resistorR62 by the current flowing in the 5 V DC output circuit. If the current is too high and thevoltage drop across R62 becomes too large, U3 cuts off the 5 V DC output to protect thepower source PCB.

24 V DC, 5 V DC and ±12 V DC from the respective output circuits are applied to comparatorZ12. When any output voltage increases to exceed the reference voltage at Z12, photocouplerZ10 turns on, which causes U2 of the pulse width control circuit to turn the FETs off to protectthe circuit from over-voltage.

Figure 2-3-10 Pulse width control circuit
In the pulse width control circuit, FET Q1 is switched on and off by the pulse signals fromthe pulse width control IC Z1. The current flowing into the primary side coil of transformerT from the smoothing circuit is switched, and an e.m.f. is generated in the secondary coil.Z1 changes the duty ratio for the pulse signals switching the FET on and off to control thevoltage output to the secondary side.When the secondary side output voltage becomes too large, shunt regulator Z4 in the errordetection circuit on the 5 V DC output circuit conducts and photocoupler Z2 turns on. Thesignal from this photocoupler is fed back to Z1 which reduces the duty cycle of the pulsesignals, so reducing the output voltage.

Figure 2-3-21 Fixing temperature error detection circuit
The voltage from fixing thermistor 1 FTH1, which changes with the temperature, is input toterminal 1 of CPU IC111 and converted from analog to digital. This data is compared withthe conditions for displaying a service call C641 to determine if there is a fixing temperatureerror.The voltage from FTH1 is input to the inverting input terminal of comparator IC3. Thereference voltage formed by dividing 5 V DC across resistors R85 and R87 is input to thenon-inverting input terminal. Normally, the voltage input from fixing unit thermistor 1 ishigher than the reference voltage, so the IC3 output voltage is low. When the temperatureof the fixing section is abnormally high, the voltage from FTH1 drops below the referencevoltage, so the voltage at the output of IC3 goes high. This high level voltage passes througha 2-stage Schmitt trigger IC20 to be shaped. The output from IC20 is input to terminal 2 ofNAND gate IC1A.The main switch on signal (low level) is constantly input to terminal 2 of the NAND gate andwhen pin 3 goes high, the high-level voltage is output at terminal 1. This output voltage isconverted to 24 V DC by driver IC TR3 and input to the base of power relay drive transistorTR2 to force TR2 off. When TR2 turns off, power feed to the power relays PRY1, 2 is cutto turn them off.

1 When the power is switched on and the 5-V-DC power source voltage rises to 4.25 V,the potential of capacitor C137 connected to the TC pin of IC118 rises.
2 As the charging of C137 continues and the potential of the TC pin rises to 2 V, the outputlevel of the RES1 pin goes high. When the potential reaches 4 V, the pin goes low andC137 is discharged.
3 When the potential of the TC pin has dropped to 2 V as C137 discharges, RES1 goeshigh again.
4 Until the clock signal is input to the WD pin from the ASIC IC41, IC118 repeats the aboveoperation. When the clock signal is received, C137 is discharged while C118 clocksignal is high.
5 When the CPU operates normally, the clock signal is always input before the potentialof TC reaches 4 V in step 2, so RES1 remains high and is always kept high while thesystem is operating normally. If the CPU has a problem, and the clock is no longer inputwith the normal timing, the potential of IC137 rises to 4 V and RES1 goes low. This RES1signal goes through the 2-stage or 4-stage inverter IC119 and is input to the CPU andASIC reset pins, resetting the CPU automatically.
6 When the 5-V-DC power source voltage drops to 4.25 V, RES1 goes low and the CPUis reset.

• Zoom processing unitProcessing for enlargement or reduction in the main scanning direction in zoom mode orprocessing in the main scanning direction in independent zoom mode is conducted at thezoom processing unit (IC103) based on the magnification ratio data computed by the CPU.Then pixel data is added or deleted at certain intervals to determine the actual enlargementor reduction.Enlargement or reduction in the sub scanning direction is controlled by changing the originalfeed motor rotational speed which is done by servo motor control 2 PCB based on themagnification ratio data from the operation unit PCB.
ReductionImage data from the input processing unit (IC112) is sent to the zoom processing unit(IC103) where a clock is generated by extending the image clock by a certain interval. Theimage data at IC103 is written line by line into SRAM using this newly created clock.Because of this, the image data in the SRAM has lost pixels at the certain intervals. Whenthe data is read out of the SRAM sequentially using the image clock, line image data seemsto be reduced.
EnlargementImage data from the input processing unit (IC112) is sent to the zoom processing unit(IC103) where a clock is generated by extending the image clock by a certain interval. IC103then writes this image data into SRAM line by line. The image data is read out of the SRAMin synch with the newly created clock. Because of this clock, some of the pixels of the imagedata stay on the data bus twice (in case of magnification ratio of 200%) as long as with theimage clock.When this data is sampled in synch with the image clock while being read into the filterprocessing unit (IC16), they are sampled twice (in case of magnification ratio of 200%) andthe line image data is now enlarged in the main scanning direction.
• Image shiftingImage is shifted in the main direction by the zoom processing IC103 which changes theimage read-out start address or image read-out timing from the line memory based on theimage shift data from CPU IC111.
• Mirror imageMirror image processing in the main scanning direction is conducted by IC103 whichchanges the image read-out start address from the line memory based on the image shiftdata from CPU IC111 and reversing the read-out order.

• Filter processing unitWhen a mode is selected on the operation panel, the CPU sets a value corresponding tothat mode on the register. This starts image differentiation or integration to make a copy asclose to the original as possible by modifying the image continuity in accordance with thetype of the original used. For example, when a photograph is used as original, integrationis conducted at the filter processing unit. Differentiation is performed for originals with text.Integration and differentiation are conducted by IC61 and FIFO (256 kbytes × 4)(IC42, 43,44 and 60).
• Tone processing unitThe tone processing unit consists of IC100 and SRAM (IC87, 88). The unit applies toneprocessing to image data sent from the filter processing unit. It also conducts grayscalemodification from 256 to 32 levels for darkness control.

Backup PCB (BUPCB) consists of SRAM, lithium battery BT1 and backup battery powersupply unit and is connected to the main PCB with connectors. SRAM is connected to CPUIC111 on the main PCB via address bus, data bus and control signals. Normally the backupPCB is driven by the 5 V DC supplied from the main PCB. Once the power is shut off, or whenthe backup PCB is disconnected from the main PCB, the lithium battery (BT1) backupsupply unit takes over. The SRAM then enters the data hold mode where memory contentsare kept for extended periods of time at a power consumption rate of as low as a few µA.

(1) Analog processing unitFour analog signals from the contact image sensor for one-line image data are output to thebuffers of the analog processing unit in synch with start signal SI from the ISU PCB. As eachsensor output has a high impedance, it is converted into a low-impedance signal by thebuffer (IC42, 36, 34, 32) at the first stage. This signal is then held by the sample hold circuitin synch with the sample hold clock (SHOLD) from IC11 to isolate the image data voltage.The output from the sample hold circuit is non-inverting-amplified by IC41, 22, 19 and 16.As the voltage when the fluorescent lamp is on varies from channel to channel, gainadjustment is conducted at 4 V.FLDA (IC38) prepares data for fluorescent lamp light intensity measurement (sensor outputfor the status where the contact glass is covered with white tape). This data is fed to the mainPCB where it is A-D converted and comprared with the reference voltage.

(2) A-D conversion/AGC processing unitImage data from the contact image sensor is converted into 8-bit digital data by the A-Dconversion circuit IC1. When reference voltages for A-D conversion are set to 5 V and 0 V,the weight of the digital data (ID0 – ID7) is 5-0/256, i.e. about 19.5 mV. However the dataobtained using the white reference plate is smaller than 5 V for the absolute white. The blackreference data also is larger than 0 V. Therefore the actual range that can be used forgrayscale correction is narrow. AGC processing is conducted to expand this range to 0 to5 V whenever the copier main switch is turned on.
(3) Shading correction circuitDue to the dispersion in sensitivity of the photosensitive elements of the contact imagesensor, uneven fluorescent lamp light distribution and distortion in the lens, there is asignificant difference in the output voltage levels of the elements of the CIS. Shadingcorrection is conducted to eliminate this difference every time an original is fed on the copier(or the first original in multiple-original copying).

The inverter PCB consists of the high-frequency pulse generating circuit from which a high-frequency pulse of 37 kHz is emitted to the fluorescent lamp and the preheat circuit for thefluorescent lamp filaments.
• Functions of signalsFL REM (CN1-2), FL CONT (CN1-1): input signalsFluorescent lamp light intensity is controlled via the light intensity control signal (FL CONT)from the main PCB. When lighting signal FL REM is at low, 37-kHz pulse is generated fromthe high-frequency pulse generating circuit and sent to the fluorescent lamp to turn it on.Then, as the control voltage of the FL CONT is increased, the lamp grows brighter; and asit is decreased, the lamp becomes dimmer (see Figure 2-3-31).

(1) Caution• When carrying out disassembly, be sure to turn the main switch off and pull out the power
cord before starting.• When handling PCBs avoid touching PCB connectors with the bare hands or scratching
equipment.• When ICs are used on PCBs, do not touch the board with the bare hands or with objects
charged with static electricity.• When replacing the fixing unit thermal switches (thermostats), be sure to use the specified
part. If a simple wire is used instead, damage to the machine may occur.• Use one of the testers shown below when measuring voltage:
