CHAPTER 1 INTRODUCTION VI. SAFETY A. 1. Laser beam safety Laser beam safety This unit has been approved as a Class 1 product based on the American DHHS (Department of Health and Human Services) Radiation Performance Standard which was enacted in 1968. This means that the laser beam emitted from this unit is not harmful.
CHAPTER 1 INTRODUCTION 2. CDRH Regulations The American CDRH (Center for Device and Radiological Health), which belongs to the Food and Drug Administration, enforced regulations regarding laser products on August 2nd1976. These regulation apply to all laser products manufactured after August 1st 1976. If product approval is not given, the product may not be sold in America. The following label indicates that the product has been approved by the CDRH regulations.
CHAPTER 1 INTRODUCTION 3. Handling the laser unit When servicing around the unit’s scanning assembly, take particular care not to put highly reflective tools, such as drivers, etc., in the path of the laser beam. Also, remove any rings when undertaking maintenance work. (There is a danger that the laser beam will be reflected into the eyes.) This unit’s laser beam is infrared. The label in the diagram below is found on covers which may reflect the laser beam.
CHAPTER 1 INTRODUCTION B. Toner safety The toner is a non-toxic substance composed of plastic, iron and a small amount of pigment. If toner gets onto skin or clothes, wipe off as thoroughly as possible with a dry tissue, then wash. If warm water is used to clean, the toner gels and soaks permanently into clothing making it then impossible to clean away the stain. Also, this toner decomposes easily with vinyl material, therefore avoid contact.

CHAPTER 4 IMAGE PROCESSING SYSTEM B. Shading correction Even when reflected light from a document with even density is detected by the CCD, the CCD output will not be consistent for the following reasons. Reason 1: There is variation in the photosensitivity of the individual CCD pixels. Reason 2: The volume of light filtered through the lens center and the peripheral areas is different. Reason 3: The volume of light from the scanning lamp centre and ends is different.

CHAPTER 4 IMAGE PROCESSING SYSTEM C. Magnification ratio process The magnification ratio in horizontal scanning direction (drum axis direction) is changed by line skipping (for reducing) when writing the image signal to the line memory, or double scanning (for enlarging) when reading out from the line memory. The magnification ratio in the vertical scanning direction is changed by increasing the speed of the mirror mount’s movement (when reducing), or reducing the movement speed (when enlarging). D.
CHAPTER 4 IMAGE PROCESSING SYSTEM E. Logarithmic correction The CCD output has linear characteristics with regards to the reflected light from the document, however, the density seen by the eye when looking at a document is not linear in relation to reflected light. Figure 4-305 shows the relationship between the document density seen by the eye, and that of the CCD output. In order to correct this, the level is adjusted, using the correction curve shown in Figure 4-306.
CHAPTER 4 IMAGE PROCESSING SYSTEM F. Half tone density processing The half tone density processing correction curve changes depending on the following: • The copy density setting on the control panel • The scanning mode (character, character/photo, photo) In accordance with the copy density setting on the control panel, there is either a light image or a dark image curve as shown in Figure 4-307.

The laser beam sensor signal is used to generate this start signal. B. BD generation / detection The DC controller PCB CPU outputs the laser forced light signal (LON*) at “0”, based on the BDI* signal, and forcibly emits the laser.
CHAPTER 5 LASER EXPOSURE SYSTEM III. LASER DRIVER CIRCUIT A. Operation This circuit turns the laser diode (LD) ON at a fixed light intensity. The fixed beam is based on a video signal (VDO*, VDO) which is sent from the image processor PCB via the DC controller PCB. The binarised image signal is converted to a VDO signal with the low amplitude differential VDO* signal, inside the image processor PCB, and sent to the DC controller PCB. Then, it is sent unchanged to the laser driver PCB receiver.

CHAPTER 6 IMAGE FORMATION SYSTEM I. OVERVIEW A. Construction The principal components of image formation system are shown in the diagram below. This unit’s image formation system uses a cartridge system. The principal components are the photosensitive drum, primary charging roller, processing cylinder, drum cleaner and toner. These are integrated to form the cartridge system.
6-2 COPYRIGHT © 1999 CANON INC.
CHAPTER 6 IMAGE FORMATION SYSTEM II. PRIMARY CHARGING ROLLER BIAS CONTROL A. Outline The primary charging roller bias is controlled by the DC controller PCB’s CPU (IC301). AC bias as well as DC bias is applied to the primary charging roller in order to stabilize the charging. • DC bias fixed voltage control • AC bias fixed current control • Bias switching control B.
CHAPTER 6 IMAGE FORMATION SYSTEM III. TRANSFER CHARGING ROLLER BIAS CONTROL A. Overview This unit employs the roller direct transfer charging system. There are 4 types of transfer charging roller bias, their respective roles and timings are explained below. 1. Transfer bias Positive voltage is applied by this bias, which transfers the toner from the photosensitive drum to the paper. 2. Cleaning bias Because a direct transfer system is employed, there are times when, because of jams, etc.
CHAPTER 6 IMAGE FORMATION SYSTEM B. Bias control The transfer charging roller bias is controlled by the DC controller PCB’s CPU (IC301). When a positive bias drive signal (TRPWM) is output from CPU, the positive bias generation circuit comes into operation. Also, when a negative bias signal (TRNFOT) is output, the negative bias generation circuit comes into operation. As mentioned before, 4 types of bias are applied to the transfer charging roller at designated times.
CHAPTER 6 IMAGE FORMATION SYSTEM IV. SEPARATION STATIC CHARGE ELIMINATOR BIAS CONTROL A. Operation The separation static charge eliminator is controlled by the DC controller PCB’s CPU (IC301) When a separation static charge eliminator bias ON signal (DCSON) is output from the CPU, the drive circuit transformer T406 comes into operation and negative voltage is applied to the separation static charge eliminator.
CHAPTER 6 IMAGE FORMATION SYSTEM V. DEVELOPING BIAS CONTROL A. Outline The circuit shown in Figure 6-501 is the circuit which controls the developing bias in the DC controller PCB. It’s principal functions are as follows: • Developing bias AC ON/OFF control • Developing bias DC ON/OFF control • Developing bias DC constant voltage control B.
CHAPTER 6 IMAGE FORMATION SYSTEM VI. RE-CHARGE BIAS CONTROL A. Operation The unit re-charges once again before fixing, in order to increase the transfer toner adhesiveness, which has been weakened by the separation static charge. The re-charge bias is controlled by the DC controller PCB’s CPU (IC301).

CHAPTER 7 PICK-UP/FEEDING SYSTEM I. OVERVIEW A. Construction Overview The construction of the unit’s pick-up feeding system is illustrated in the diagram below. The pick-up feeding system rollers in the main unit are all driven by the main motor (M601) via the gear and clutch. ■ Jam detection sensors Symbol PS301 PS302 Sensor name Paper leading edge sensor Registration sensor PS303 Paper sensor PS306 Delivery sensor Function Detects the paper’s leading edge and controls the laser ON timing.
CHAPTER 7 PICK-UP/FEEDING SYSTEM II. PICK-UP FEEDING OPERATION A. Overview The unit’s pick-up feeding system is controlled by the DC controller PCB’s CPU (IC301). The pick-up feeding system’s rollers are all driven by the main motor (M601) via the gear and clutch. The paper picked-up from the paper cassette and multi-feeder is fed to the registration roller unit by the vertical path roller, which is driven by the vertical path clutch (CL301).
CHAPTER 7 PICK-UP/FEEDING SYSTEM III. CASSETTE PICK-UP MECHANISM A. Pick-up operation The pick-up roller rotation is controlled by both the pick-up roller drive gear which transmits the main motor’s (M601) drive to the pick-up drive axis gear, and the pick-up solenoid (SL301). The construction of the cassette pick-up assembly is illustrated in Figure 7-302. When the main motor rotates, the connected drive relay gear also begins to rotate.
CHAPTER 7 PICK-UP/FEEDING SYSTEM The above diagram shows a unit equipped with an ADF. The construction of the main unit is also the same for units not equipped with the ADF. Feed roller drive gear Pick-up roller drive gear Drive relay gear Pick-up solenoid Rotation Rotation Rotation Gears are engaged Solenoid ON Rotation Pick-up drive axis gear The pick-up roller drive gear is at a standstill due to the pick-up solenoid being OFF.
CHAPTER 7 PICK-UP/FEEDING SYSTEM B. Retry pick-up When paper is not picked-up even when the pick-up roller is rotating, the retry pickup operation occurs. The DC controller PCB’s CPU counts the time from when the paper solenoid (SL301) comes ON. If the pick-up sensor (PS303) cannot detect the paper’s leading edge within a designated period of time, the pick-up solenoid comes ON again and the pick-up operation is retried.
CHAPTER 7 PICK-UP/FEEDING SYSTEM C. Paper size detection The size of the paper inside the cassette is monitored by the DC controller PCB’s CPU. The CPU detects the change in position of the cassette paper size lever which is set by the customer. When the cassette is inserted into the main unit, the paper size lever presses the main unit’s paper size switch and therefore the presence of paper in the cassette and also the paper size is monitored.
CHAPTER 7 PICK-UP/FEEDING SYSTEM IV. MULTI-FEEDER PICK-UP A. Overview The multi-feeder is the mechanism which continuously picks-up paper stored in the multi-feeder tray. The paper is picked-up from the top. The paper in the tray is lifted up by the lifter plate and pressed down by the multi feeder pick-up roller. The multi-feeder pick-up roller is driven by the main motor (M601), via the solenoid and gear.
CHAPTER 7 PICK-UP/FEEDING SYSTEM B. 1. Multi-feeder pick-up mechanism Lifter plate operation The mechanism for raising the lifting plate is illustrated in the diagram below. During standby, the lifter plate is supported and lowered by the cams fitted onto the front and rear of the multi-feeder pick-up roller. When the paper roller rotates, the cams are also made to rotate, causing the lifter plate to rise, and the paper set in the multi-feeder comes into contact with multi-feeder pick-up roller.
CHAPTER 7 PICK-UP/FEEDING SYSTEM 2. Multi-feeder pick-up drive mechanism The multi-feeder pick-up roller is driven by the main motor, via the multi-feeder pickup drive assembly gear. The pick-up timing is controlled by multi-feeder pick-up solenoid drive signal (SL302D), which is sent from the DC controller PCB. The construction of the multi-feeder pick-up drive assembly is illustrated in Figure 7403. When the main motor rotates, the pick-up drive relay gear rotates simultaneously.
CHAPTER 7 PICK-UP/FEEDING SYSTEM D. Multi-feeder paper size setting The multi-feeder paper size setting differs, depending on how the multi-feeder is used. a) When using the multi-feeder with a fixed paper size. b) When resetting the size when replenishing the multi-feeders paper. For a), designate the paper size by: Registration/Setting key > 01 Data registration > 05 Printer settings > 06 Name stack size “ON”. If 06 Name stack size “OFF” is selected, the size needs to be set as for the above b).
CHAPTER 7 PICK-UP/FEEDING SYSTEM Multi-feeder pick-up roller Pick-up drive transmission gear Cogless gear [1] The pick-up solenoid comes into operation, the cogless gear lock is released. Spring [2] When the lock is released, the cogless gear rotates a little due to the spring’s power. [3] [2] [3] Drive from the motor is transmitted to the cogless gear causing it to begin rotation.
CHAPTER 7 PICK-UP/FEEDING SYSTEM V. PAPER FEEDING OPERATION A. Paper leading edge detection The paper sent from the pick-up assembly is sent to the transfer area by the registration clutch (CL302) rotation. A sensor is installed in front of the transfer area which detects the leading edge of the paper sent from the registration roller. The DC controller PCB sends a vertical synchronizing signal (TOP*) to the image processor PCB when the paper leading edge sensor (PS301) detects the paper’s leading edge.
CHAPTER 7 PICK-UP/FEEDING SYSTEM VI. JAM DETECTION A. Overview The unit is equipped with 4 jam sensors to detect the condition of the paper feeding. In addition, the unit is equipped with one sensor to detect paper presence in the multi-feeder and one sensor to detect paper presence in the cassette. In order to check the presence of paper and jams, the DC controller PCB’s CPU (IC301) checks at pre-programmed check timing intervals whether there is paper in the sensor areas.
CHAPTER 7 PICK-UP/FEEDING SYSTEM B. Types of Jam The DC controller PCB microprocessor (IC301) determines there is a jam in the following situations a. Delay jam The copy paper has not arrived in the sensor area within a stipulated period of time (not detected by the sensor). b. Stationary jam The paper has not left the sensor within a stipulated period of time after the sensor has detected the copy paper (the sensor has not turned OFF). c.
CHAPTER 7 PICK-UP/FEEDING SYSTEM ■ Detection by the registration sensor (PS302) The conditions for detection by the registration sensor differ from the time of the first sheet pick-up operation and the second and subsequent sheet pick-up in consecutive paper feed. a. Delay jam at the time of the first sheet pick-up When paper has not arrived at the registration sensor (PS302) within approx. 2.3 seconds after the pick-up sensor (PS303) has turned ON, it is judged that a delay jam has occurred.
CHAPTER 7 PICK-UP/FEEDING SYSTEM b. Delay jam at the time of the second or subsequent sheet pick-up. In this case there are 2 types of timing which monitor the feeding situation. Detection and jam judgement is done by both these timings. • A jam is determined at the same timing as the previously explained delay jam at the time of the first sheet pick-up.
CHAPTER 7 PICK-UP/FEEDING SYSTEM 2. Pick-up delay jam (in the case of multi-feeder pick-up) The pick-up from the multi-feeder is monitored by the registration sensor (PS302) The timer count begins after the multi-feeder pick-up solenoid (SL302) has come ON, or, in the case he second sheet during multiple sheet continuous pick-up, after the paper sheet previously picked up has passed through the registration sensor. If paper has not arrived at the registration sensor approx.1.
CHAPTER 7 PICK-UP/FEEDING SYSTEM 3. Registration sensor stationary jam (for cassette pick-up) A registration sensor (PS302) stationary jam is only detected when continuous multiple sheet pick-up takes place. At the time of the following sheet pick-up, the jam detection starts within approx. 3.0 seconds after the pick-up sensor (PS303) has turned ON (the following sheet leading edge is in a position of approx. 10mm in front of the vertical path roller). If approx. 2.
CHAPTER 7 PICK-UP/FEEDING SYSTEM 4. Registration sensor stationary jam (for multi-feeder pick-up) In the case of multi-feeder pick-up, if, after the multi-feeder pick-up solenoid (SL302) has come ON from the second or subsequent sheet pick-up, the preceding paper has not left the registration sensor (PS302) after approx. 1.0, it is judged that a registration sensor stationary jam has occurred. Start signal First sheet Second sheet Third sheet Multi-feeder pick-up solenoid (SL302) 1.0 sec.
CHAPTER 7 PICK-UP/FEEDING SYSTEM 6. Paper leading edge sensor delay jam (for multi-feeder pick-up) In the case of multi-feeder pick-up, if paper has not arrived at the leading edge sensor (PS301) after approx. 1.2 seconds after the registration clutch (CL302) has come ON, a retry pick-up takes place. If paper has not arrived at the paper leading edge sensor approx. 1.2 seconds after the registration clutch operation for the retry pick-up has come ON again, yet another retry takes place.
CHAPTER 7 PICK-UP/FEEDING SYSTEM 8. Delivery sensor delay jam If the delivery sensor (PS306) does not come ON after 5 seconds has passed since the paper leading edge sensor (PS301) has come ON, it is judged a delivery sensor delay jam has occurred. Start signal Paper leading edge sensor (PS301) Delivery sensor jam check 5.0 sec. Delivery sensor (PS***) 5.0 sec. Normal Abnormal Main motor (M601) Figure 7-613 9.
CHAPTER 7 PICK-UP/FEEDING SYSTEM 10. Fixer wraparound jam It is judged there is a fixer wraparound jam if paper has wrapped around the fixer, causing the delivery sensor to turn OFF within 1.4 seconds after the delivery sensor (PS306) has detected the paper leading edge. Start signal Delivery sensor (PS306) Delivery sensor jam check 1.4 sec. Normal 1.4 sec. Abnormal Main motor (M601) Figure 7-615 11. Door open jam.

CHAPTER 8 FIXING SYSTEM II. FIXING CONTROL A. 1. Fixing temperature control Overview This unit’s fixing heater uses two surface heaters, which are installed into one ceramic base. The heater heats up the fixing film. The two surface heaters are equipped with ON/OFF switches, which keep the power consumption low. The temperature of the fixing heater is monitored by a thermistor (TH1), which is located on top of the fixing heater.
CHAPTER 8 FIXING SYSTEM Reference: When the amount of time which has lapsed between the delivery sensor (PS306) detecting the end of one paper, and the next paper passing the through the paper leading edge sensor (PS301) is less than one second, the temperature control changes to the paper interval temperature control. When compared to printing at 1200dpi equivalent, the feeding speed when printing at 600dpi is doubled, and so the fixing target temperature is high.
CHAPTER 8 FIXING SYSTEM B. Fixing heater safety mechanism This unit is equipped with a fixing heater safety circuit, located inside the DC controller PCB, which monitors the fixing temperature for abnormal rises in temperature. Should an abnormality occur, the output from the main circuit will switch the relay (RL1), located on the power supply PCB, to the OFF position, which cuts off the power supply to the fixing heater.

CHAPTER 10 CASSETTE FEEDER I. OVERVIEW The cassette feeder structure is displayed in the diagrams below. The unit may be equipped with a one level cassette feeder or with a three level cassette feeder unit. The structure of each cassette feeder is the same, and each cassette feeder is equipped with a pick-up assembly and a feeder controller PCB, which controls the operation of the pick-up assembly.
CHAPTER 10 CASSETTE FEEDER Reference: With the three level cassette feeder, in the lowest cassette feeder there is no interface connector provided between this and a lower feeder. Therefore, the lowerst cassette feeder cannot be used as the first or second cassette feeder. Interface connector Interface connector First cassette feeder Second cassette feeder Interface connector Third cassette feeder Figure 10-103 10-2 COPYRIGHT © 1999 CANON INC. CANON GP160 REV.0 FEB.
CHAPTER 10 CASSETTE FEEDER II. OVERVIEW OF THE ELECTRICAL CIRCUITS A. Overview Operation of the load used by the cassette feeder is controlled by commands sent from the CPU (IC301) on the main unit’s DC controller PCB, based on the programme stored in the CPU (IC601) on the feeder controller PCB.
CHAPTER 10 CASSETTE FEEDER III. FEEDER CONTROLLER PCB INPUT AND OUTPUT Feeder controller PCB Pick-up sensor Paper sensor PS651 +5V J655-1 -3 PS651S* -2 “0” when the PS651 detects paper. (when the light-blocking plate is not at PS301) PS652 +5V J655-4 -6 PS652S -5 “1” when the PS652 detects paper.
CHAPTER 10 CASSETTE FEEDER IV. OPERATION OVERVIEW A. Overview Figure 10-401 is the concept figure of the structure of the cassette feeder. The cassette feeder’s operation is controlled by the feeder controller PCB. The main unit’s DC controller PCB sends the pick-up control signal to the feeder controller PCB. When the feeder controller PCB receives the pick-up control signal, the feeder motor (M651) begins to rotate, and the pick-up solenoid is turned ON.
CHAPTER 10 CASSETTE FEEDER B. Basic Sequence Main unit delivery sensor (PS306) Main unit paper leading edge sensor (PS301) Main unit registration clutch (CL302) Main unit registration sensor (PS302) Pick-up sensor (PS651) Pick-up solenoid (SL651) Feeder motor (M651) Main unit main motor (M601) Start Key ON Condition: When 2 pieces of A4 paper are picked up from the first level cassette feeder Figure 10-402 10-6 COPYRIGHT © 1999 CANON INC. CANON GP160 REV.0 FEB.
CHAPTER 10 CASSETTE FEEDER V. FEEDER MOTOR CONTROL A. Operation The feeder motor (M651) of this unit uses a stepping motor. The A phase pulse circuit and the B phase pulse circuit, located on the feeder controller PCB, emit drive pulses (A • A* • B • B*). Changes in the order and frequency of the pulses control the rotation.
CHAPTER 10 CASSETTE FEEDER VI. JAM DETECTION A. Overview The cassette feeder is equipped with a pick-up sensor (PS651), which monitors the pick-up and feeding function. It is also equipped with a paper supply sensor, which detects the presence or absence of paper. According to a pre-programmed timing, the feeder controller PCB’s CPU (IC601) performs checks to determine whether there is paper or not in the sensor area, as well as checks for jams.
CHAPTER 10 CASSETTE FEEDER B. 1. Jam Sensing Pick-up delay Jam During the cassette feeding sequence, once the pick-up solenoid (SL301) is ON, if the paper does not arrive at the pick-up sensor (PS303) within 3 seconds, the feeding operation is retried. Once again, if the pick-up sensor does not come ON in the 3 seconds following the activation of the pick-up solenoid, the unit determines that a delay jam has occurred.
CHAPTER 10 CASSETTE FEEDER 2. Registration sensor delay jam Following the activation of the pick-up sensors in each of the cassette feeder levels, if the paper does not arrive at the registration sensor (PS302) within the designated amount of time, a registration sensor delay jam has occurred. These are the detection timings for each cassette feeder: Pick-up level Cassette feeder first level Cassette feeder second-level Cassette feeder third-level Timer count time Approx. 2.4 seconds Approx. 2.
