ROUTINE WORK BY THE USER Advise the user to clean the following at leas once a week: 1) Copyboard Glass Wipe it with a moist cloth; thereafter, dry wipe it. 2) Copyboard Cover/RDF Feeding Belt Wipe them with a cloth moistened with a solution of mild detergent; then, dry wipe them. COPYRIGHT © 1996 CANON INC. Advise the user to perform the following when image faults (e.g., vertical white spots) are noted: 1) Clean the charging roller and the transfer roller in user mode.
1. GENERAL DESCRIPTION VI. SAFETY A. Laser Beams Since laser beams can be haemful to the human body, the copier’s scanner system is enclosed within a protective housing and external covers, thereby preventing leakage of laser beams outside. For this reason, there is no likehood of the user’s coming into contact with laser beams. The copier is approved as a Class 1 laser product under IEC825 and, in the USA, as Class under the Code of Federal Regulations (1040.
1. GENERAL DESCRIPTION B. Safety of Toner Toner is a non-toxic material consisting of plastic, iron, and small amounts of dye. If toner comes into contact with the skin or clothing, remove it with dry tissue and wash with water. Do not use hot water, as such will turn the toner into gel and cause it to fuse with the fibers of the cloth. Further, do not bring toner into contact with plastic material, as such will initiate chemical reaction. Caution: Do not dispose of toner in fire. It may explode.

2. COPYING PROCESS The GP215/GP200’s image formation process consists of the following steps as discussed in sequence: Step 1 Pre-exposure Step 2 Primary charging (AC + negative DC) Step 3 Laser exposure (AC + negative DC bias) Step 5 Transfer (positive DC) Step 6 Separation (negative DC) Step 7 Fixing Step 8 Drum cleaning The photosensitive drum has a layer construction: the outside is a photoconducting layer of OPC and the inside, conductive aluminum substrate. B.
2. COPYING PROCESS C. Pre-Exposure (step 1) D. Primary Charging (step 2) Primary charging roller Figure 2-106 Figure 2-105 Before executing primary charging, light from the pre-exposure lamp is directed to the surface of the drum (pre-exposure), thereby removing residual charges from the surface and, ultimately, preventing uneven copy density. COPYRIGHT © 1996 CANON INC.
2. COPYING PROCESS E. Laser Exposure (step 3) F. Development (step 4) Laser light Blade Cylinder Dark area Light area Magnet Developing cylinder Figure 2-107 Figure 2-108 In this step, a laser representing the dark areas of the original is directed to the surface of the drum to neutralize the existing charges. The areas on the photosensitive drum which have been exposed this way are called light areas and will later attract toner in step 4 (development).
2. COPYING PROCESS A concentrated magnetic field occurs from the magnet to the edge of the blade, attracting toner. Once inside the field, the toner becomes virtually immobile because of the strong bond with the blade so that, when deposited, it forms an even, thin layer on the cylinder. An AC bias and a DC bias (negative component) are applied to the developing cylinder and the blade at the same time (developing bias); the negative component of the developing bias is stronger than the positive component.
2. COPYING PROCESS Reference: If the image on the photosensitive drum was not fully transferred to the copy paper because of a jam, toner can stick to the transfer charging roller. The GP215/GP200 uses negative transfer voltage during initial rotation and last rotation to return any such toner (charged to a negative potential and sticking to the transfer roller) to the photosensitive drum.

3. OPERATIONS AND TIMING B. Varying the Reproduction Ratio The reproduction ratio in the main scanning direction (drum axis) is changed by skipping (reduction) image signals when writing into line memory or reading a multiple number of times (enlargement) when reading from the line memory. The reproduction ratio in the sub scanning direction, on the other hand, is changed by moving the mirror mount faster (reduction) or slower (enlargement). C.
3. OPERATIONS AND TIMING D. Scanner Motor 1. Outline The scanner motor (M2) is a stepping motor, and the motor is controller by the DC controller PCB. The CPU on the DC controller PCB sends to the motor controller PCB through the I/O circuit such commands as clockwise rotation (moving the scanner forward), counterclockwise rotation (moving the scanner in reverse), and rotation speed.
3. OPERATIONS AND TIMING E. Controlling the Scanning Lamp 1.
3. OPERATIONS AND TIMING 2. Controlling Pre-Heating 4. Controlling the Intensity The filament of the scanning lamp is powered so as to speed up the time in which the intensity of the scanning lamp reaches its optimum value after a press on the Copy Start key. (This mechanism is called pre-heating.) Pre-heating may be full pre-heating or scanning lamp ON pre-heating. a. Full Pre-Heating Power is applied during initial rotation. b. ON Pre-Heating Power is applied during copying operation.
3. OPERATIONS AND TIMING F. Identifying the Size of Originals 1. Outline The original size detection mechanism of the copier or the feeder is used as necessary to detect the size of an original placed on the copyboard or in the feeder.
3. OPERATIONS AND TIMING 2. Operation of Original Size Sensors a. A3 black original b. Book original (The thickness of a book prevents changes in the sensor level.) c. The copyboard cover is not closed. (PS3 is OFF.) A reflecting type sensor is used under the copyboard glass to detect the size of an original placed on the copyboard glass. When the copyboard cover is brought down to about 30°, the photointerrupter (PS3) located at the rear of the copier turns ON, i.e., the lightblocking plate blocks PS3.
3. OPERATIONS AND TIMING 3. Detecting the Size of Originals Using the combination of the outputs of the sensors representing the presence/absence of an original, the image processor PCB identifies the size of the original as shown in Tables 3-206 through -208. • Same Indicates that there is no change in the sensor output, i.e., the presence of an original is assumed. (The sensor output is checked every 128 ms after the copyboard cover has turned ON.
3. OPERATIONS AND TIMING III. IMAGE PROCESSING A. Outline The image processing system converts the optical image projected on the CCD into electrical signals (image signals) for correction and processing.

Image processor PCB • • • • • • • Shading correction Reproduction ratio processing Filter processing Negative/positive reversal Framing/blanking Density processing Binary processing (for copy images) • D/A conversion To the laser driver PCB and the CORE/IP PCB.
3. OPERATIONS AND TIMING B. Analog Image Processing 1. Outline The analog processor PCB converts CCD drive signals and CCD output signals (analog signals) to digital signals. (It also executes AE measurement.) 2. CCD/CCD Driver The GP215/GP200’s CCD is a linear image sensor consisting of a single line of 7500 photocells. The signals subjected to photoelectric conversion in the photocell unit are forwarded to the CCD drive circuit. (The even-number pixels and the odd-number pixels are sent separately.
3. OPERATIONS AND TIMING 3. A-D Conversion Circuit/ABC Circuit a. A-D Conversion Circuit The A-D conversion circuit converts analog signals from the CCD to 8-bit digital image signals. In general, the A-D conversion signal performs A-D conversion based on the reference voltage. As such, increasing/decreasing the reference voltage will increase/decrease the dynamic range (difference between maximum output level and minimum output level), affecting the signal level after A-D conversion.
3. OPERATIONS AND TIMING C. Digital Image Processing 1. Outline The digital image processing block serves to process image signals from various functions boards. See Figure 3-304 for a block diagram of various image processing functions: Analog processor PCB Shading correction Total processing . Reproduction ratio . Slant . Mirror image . Repeat . Folding . Edge emphasis . Smoothing . Negative/ positive reversal . Framing .
3. OPERATIONS AND TIMING 2. Shading Correction The output of the CCD will not be constant for the following factors even when the light reflected by an original with even density is projected to the CCD. 1 The sensitivity of each pixel of the CCD is not the same. 2 The degree of transmission of the lens is different between the center and the sides. 3 The intensity of the scanning lamp is different between the center and the sides. 4 The scanning lamp can deteriorate.
3. OPERATIONS AND TIMING The total processing block deals with the following: • Reproduction ratio • Shift • Mirror image • Slanting • Repeat • Folding a. Reproduction Ratio q Horizontal Reproduction Ratio (main scanning direction) When writing image data into memory, data units may be skipped for reduction; when reading them from memory, they are read a multiple number of times (enlargement).
3. OPERATIONS AND TIMING b. Shift Processing Figures 3-309, -310, and -311 give samples of image shifting and conceptual outlines of shifting in main/sub scanning direction.
3. OPERATIONS AND TIMING The image of an original may be shifted as follows by combining shifts in main and sub scanning directions. q Corner Shift The coordinates (X1, Y1) of the corner of a specific area is moved to any of the four corners of the copy. w Center Shift The coordinates (Xm, Ym) are computed from the size of the area to be shifted and the size of the copy so that the margins at the top and bottom and left and right will be identical; the area will be moved to X1 and Y1.
3. OPERATIONS AND TIMING c. Reduced Image Composition Reduced image composition mode may be any of the following two: q 2-on-1 mode, in which two originals are reduced for copying on a single sheet of copy paper. w 4-on-1 mode, in which four originals are reduced for copying on a single sheet of copy paper. Executing these modes requires control under combination of reproduction ratio processing, shift processing, and overlay processing.

3. OPERATIONS AND TIMING d. Enlarged Image Composition In enlarged image composition, the reduced image of an original is returned to its original size; it may be any of the following four: • 2-on-1, generating 2 outputs • 2-on-1 two-sided, generating 4 outputs • 4-on-1, generating 4 outputs • 4-on-1 two-sided, generating 8 outputs.

3. OPERATIONS AND TIMING 4. Sharpness/Filter Processing a. Sharpness/Filter Processing In sharpness/filter processing, computations are performed so that a crisp or soft image may be obtained as specified on the control panel. Figure 3-328b shows the output level occurring as the result of selecting ‘sharpness mode weak’ for the image data shown in Figure 3-328a. In ‘sharpness mode weak’, the variations in the density of an image are smoothed out to generate a soft image.
3. OPERATIONS AND TIMING b. AI Outline processing AI outline processing emphasizes the edges of characters. When image data input is as shown in Figure 3-329, the CPU assumes the presence of characters and initiates outline processing. When image data input is as shown in Figure 3-331, the CPU assumes the presence of a photo and does not initiate outline processing.
3. OPERATIONS AND TIMING 5. Negative/Positive Reversal The negative/positive reversal circuit executes the following image processing: • Negative/positive reversal • Framing • Blanking • Pasting a. Negative/Positive Reversal Level conversion is executed so that the white area of an original will be black and the black area will be white on copies. b. Framing/Blanking For framing/blanking, areas may be as many as 4 areas; for a rectangle, as many as 10 points may be specified.
3. OPERATIONS AND TIMING 6. Density Processing a. Logarithmic Correction The CCD output has linear characteristics in relation to the light reflected by an original. However, the density of an original as perceived by the human eye does not show linear characteristics in relation to the light reflected by the original. The relationship between the density as perceived by the naked eye and the output of the CCD are as shown in Figure 3-336. CCD output 255 b.
3. OPERATIONS AND TIMING The GP215/GP200’s AE may be ‘priority on speed’ (default) or ‘priority on image quality’. (Here, the discussions are on ‘priority on image quality’; for ‘priority on speed’, see p. 3-32.) In ‘priority on image quality’, the density correction curve is varied according to the type of original. In ‘priority on image quality’, the scanner is moved forward to suit the size of the detected original, thereby executing full scanning for measuring the density of the entire original.
3. OPERATIONS AND TIMING 7. Binary Processing 8. D-A Conversion The binary processing circuit converts multiple-value image signals into binary signals. The method used here is called the PD method, which enables better reproduction of highlight areas than the median density (MD) retention method. Binary processing is executed in text mode and text/photo mode. The D-A conversion circuit is used to convert multiple-value image signals into analog signals.

3. OPERATIONS AND TIMING B. Generating the BD Signal A laser ON signal (horizontal sync signal) is needed when directing a laser beam to the photosensitive drum, and the laser beam detection signal (BD) is used to generate such a start signal. The GP215/GP200 is designed to detect the edge of copy paper which has been re-picked up for twosided/overlay copying to measure the discrepancy, if any, toward the rear/front.
3. OPERATIONS AND TIMING C. Laser Driver Circuit 1. Operation The optical output of the laser (semiconductor laser) is affected largely by changes occurring in the ambient temperature. The GP215/GP200 uses a control mechanism which varies the laser drive current automatically to suit the ambient temperature, thereby ensuring a specific output.

Switching the Laser Output The laser output may be either high, medium, or low, ensuring the best image for the selected mode.
3. OPERATIONS AND TIMING D. Controlling the Laser Scanner Motor 1. Operation The laser scanner motor rotates in response to the instructions from the DC controller PCB, and its supply power is controlled by the scanner driver PCB. The laser scanner motor(M3) rotates when the laser scanner motor drive signal (LMD=1) is sent by the DC controller PCB to the scanner driver PCB. At this time, the hall IC output signal returns from M3 for controlling the supply power used to rotate M3.
3. OPERATIONS AND TIMING 2. Turning ON and OFF the Laser Scanner Motor The laser scanner motor (M3) starts to rotate differently depending on whether ‘time to quiet mode’ in user mode is set to ‘1–9’ or ‘0’. If the time is set to ‘1–9’, rotation starts when the following is performed during standby: q Pressing a key. w Opening the copyboard cover or the feeder. e Placing an original in the feeder. If the time is set to ‘0’, rotation starts when the Copy Start key is pressed.

Outline The bias for the primary charging roller is controlled by the composite power supply PCB according to the instructions from the DC controller PCB. In addition, an AC bias is applied to the primary charging roller to ensure stable charging.
3. OPERATIONS AND TIMING 2. Turning OFF and ON the Primary Charging Roller 3. Controlling the Primary Charging Roller Bias The primary charging roller is turned ON and OFF by the primary charging roller ON/OFF signal (HVPDC) from the DC controller PCB. The primary side of the main transformer (T101) on the composite power supply PCB operates under the control of the CPU (Q605).
3. OPERATIONS AND TIMING 4. Correcting the Drum Surface Potential 5. Resistance of the Photosensitive Drum The drum surface potential fluctuating in relation to changes in the machine internal temperature is corrected by varying the primary charging roller bias voltage. The machine internal temperature is detected by the thermistor mounted to the rear plate of the machine, and the data is sent to the CPU on the DC controller PCB.
3. OPERATIONS AND TIMING C. Controlling the Transfer Charging Roller Bias 1. Outline The GP215/GP200 uses direct transfer executed by means of a roller.
3. OPERATIONS AND TIMING a. Transfer Bias This bias is used for transfer of toner from the photosensitive drum to copy paper and is of a positive voltage. For output timing, see Figure 3-505. b. Cleaning Bias Since the machine uses direct transfer, toner from the photosensitive drum can stick to transfer charging roller because of a jam.
3. OPERATIONS AND TIMING 2. Controlling the Transfer Charging Roller Bias The transfer charging roller bias is controlled by the CPU (Q605) on the composite power supply PCB according to instructions from the DC controller PCB. a. Switching between Bias Types The aforementioned bias types are switched based on combinations of the transfer output mode 0 (HVTM0) and the transfer output mode 1 (HVTM1) from the DC controller PCB. (See Table 3-501.
3. OPERATIONS AND TIMING D. Controlling the Developing Bias 1. Outline Figure 3-506 shows the circuit used to control the developing bias of the composite power supply PCB, and the circuit has the following functions: • Turning ON and OFF the AC component of the developing bias. • Turning ON and OFF the DC component of the developing bias. • Controlling the DC component of the developing bias to a specific voltage.
3. OPERATIONS AND TIMING 2. Turning ON and OFF the DC Component of the Developing Bias 4. Turning ON and OFF the AC Component of the Developing Bias The DC component of the developing bias is turned ON and OFF by the DC bias ON/OFF signal (DCON) from the DC controller PCB. The primary side of the main transformer (T101) on the composite power supply PCB operates under the control of the CPU (Q605).
3. OPERATIONS AND TIMING E. Controlling the Separation Static Eliminator Bias 1. Turning ON and OFF the Separation Static Eliminator Bias The separation static eliminator ON signal (SEBON) causes the CPU (Q605) on the composite power supply PCB to drive the separation static eliminator bias drive circuit to apply a bias on the separation static eliminator. 2.
3. OPERATIONS AND TIMING F. Controlling the Transfer Guide/Fixing Roller Bias 1. Transfer Guide Bias The transfer guide bias is used to prevent adhesion of toner to the transfer guide and has a negative potential (–600 VDC) as in the case of toner. The application continues as long as the control panel power remains ON. 2. Lower Fixing Roller Bias A positive component is applied to the steel core of the lower fixing roller to prevent offset to the fixing film.
3. OPERATIONS AND TIMING G. Developing Assembly/Drum Cleaner 1. Outline The developing assembly is locked manually by operating the locking lever for each developing rail. The developing cylinder, stirring rod in the developing assembly, and the feeding blade inside the drum cleaner are rotated by the drive of the main motor. The level of toner is detected in reference to the toner absent signal (TEP) from the toner level sensor (TS1) inside the developing assembly.
3. OPERATIONS AND TIMING ■ Computation of Toner Level Detection Result cleared Result cleared Toner present Toner absent (TEP*occurs) T1 T2 T1 T2 T1 T2 Figure 3-510a Since toner is stirred by the stirring rod inside the developing assembly, the toner absent and present states repeat at intervals as shown in Figure 3-510a. • The absence of toner is assumed by monitoring TEP* only while the developing clutch remains ON; i.e., such periods as when the developing clutch remains ON are added.
3. OPERATIONS AND TIMING 3. Detecting Waste Toner The waste toner that has been scraped by the cleaning blade is forwarded to the rear of the cleaner housing by the waste toner feeding blade inside the drum cleaner. The coupling shown in Figure 3-511 is pushed against the blade under the pressure of a spring to transmit the drive of the main motor to rotate the blade.
3. OPERATIONS AND TIMING H. Primary Charging Roller Cleaning Mechanism 1. Outline The GP215/GP200 is equipped with a mechanism which automatically cleans the primary charging roller. The primary charging roller cleaning solenoid (SL1) is turned ON while the primary charging roller is rotating to butt the cleaning pad against the primary charging roller while, at the same time, the primary charging roller is moved back and forth in the axial direction of the primary charging roller.
3. OPERATIONS AND TIMING I. Detecting Errors on the Composite Power Supply PCB The composite power supply PCB is equipped with a self diagnostic function which checks for an error in the output of the PCB and its communication with the DC controller PCB. The results of detection are indicated by changing the intervals at which LED100 on the DC controller PCB flash. (See p. 3-75.) At the same time, the results are sent to the image processor PCB to indicate an error code on the control panel.
3. OPERATIONS AND TIMING ■ Status Indications by Flashing LED Classification Flashing intervals Intervals of 0.5 sec 0.5sec Description Normal The composite power supply PCB is operating normally. Overcurrent The composite power supply PCB has detected an overcurrent because of trapped wiring or an error in a load in relation to +24VR or +24VU output. Low-voltage control error in standby The difference between the setting for +24VR output and the control value in standby is larger than specified.
3. OPERATIONS AND TIMING VI. PICK-UP/FEEDING SYSTEM A. Outline The GP215/GP200 uses center reference, in which copy paper moves along the center of the pickup/feeding assembly. The pick-up system consists of two cassettes (upper, lower) and the multifeeder. Copy paper from any of the cassettes or the multifeeder is controlled by the registration roller so that its leading edge matches the leading edge of the image on the photosensitive drum; the paper is then sent to the copy tray.

3. OPERATIONS AND TIMING 3. Cassette Lifter Operation As long as the cassette is set, the cassette lifter is operated as necessary during copying operation so as to maintain the level of the paper stack at a specific position. a. Lifter Movement during Copying The stack surface is maintained at a specific height by operating the lifter during copying as follows: The lifter movement starts when the pick-up roller shaft pushes the lifter trigger lever to release the cam.
3. OPERATIONS AND TIMING 3) The rotation of the cam moves the lever, thereby lifting the lever. Lifter gear Figure 3-607 4) The stack surface rises in response to the rising lifter; since the height of the pick-up roller shaft will also increase, the spring pulls the lever to restrain the cam.

3. OPERATIONS AND TIMING b. Releasing the Lifter The lifter drive is released mechanically in that it is released when the cassette is slid out. As many as two types of claws are at work (one moving up the lifter and one holding the lifter). When the machine is in standby state, the lifter gear is supported by the retaining claw; when the cassette is slid out, the retaining claw is released to let the lifter down.

3. OPERATIONS AND TIMING c. Moving Up/Down (pick-up) the Pick-Up Roller The pick-up roller and the feeding roller are supported by a roller holder, and the pick-up roller operates around the feeding roller shaft. The up/down movement of the pick-up roller shaft is driven using the drive of the main motor (M1) through the cam 1 controlled by the pick-up solenoid (SL2). In standby, the pick-up roller shaft is at uppermost position.
3. OPERATIONS AND TIMING d. Detecting the Absence of Paper inside the Cassette When the cassette runs out of copy paper, the paper detecting lever falls through the detecting slit in the cassette. The paper detecting lever operates in conjunction with the light-blocking plate so that the light-blocking plate blocks the respective photointerrupter (Q1604 for the upper cassette; Q1605 for the lower cassette), thereby indicating the absence of paper inside the cassette.
3. OPERATIONS AND TIMING C. Non-Pick Up Operation (standby) The machine operates as follows when the cassette is slid into or out of the machine. 1. Lifter Up/Pick-Up Roller Shaft Down (sliding in the cassette) a. Pick-Up Roller Shaft Down When the cassette is installed while the main power supply is ON, the following cause the pick-up roller shaft to lower until it comes into contact with the surface of the copy paper: • The rear end of the cassette pushes in the lever 1 of the pick-up unit mechanically.
3. OPERATIONS AND TIMING 2. Moving Up the Pick-Up Roller Shaft and Releasing the Lifter/Separation Roller (sliding out the cassette) a. Moving Up the Pick-Up Roller Shaft and Releasing the Separation Roller • Moving Up the Pick-Up Roller Shaft When the cassette is slid out, the force of the spring rotates the lever 1. The rotation of the lever 1 moves up the pick-up roller shaft s that the pick-up roller and the cassette will not interfere with each other.
3. OPERATIONS AND TIMING D. Detecting the Level of Copy Paper The machine checks the level of copy paper inside the cassette and indicates the level in four degrees. The level of copy paper inside the cassette is checked in reference to the up movement of the lifter noted when the light-blocking plate blocks the appropriate sensor. When copy paper starts to run out, the lifter rises gradually;when paper fully runs out, the cassette paper sensor (Q1604 for upper) detects the absence of paper.

3. OPERATIONS AND TIMING 3. Cassette Size The upper cassette and the lower cassette differ in size. The upper cassette may be used for copy paper of B4 or smaller. Inside the cassette are the side guide plates (side/rear end), which must be adjusted by hand. Since the size guide plates are not equipped with a sensor, you must set the aforementioned rotary switch correctly.
3. OPERATIONS AND TIMING F. Multifeeder 1. Outline The multifeeder is a mechanism in which a stack of copy paper placed on the multifeeder tray is picked up one by one from the top. The copy paper stacked on the tray is pushed against the pick-up roller by the paper guide. The drive of the multifeeder pick-up roller comes from the main motor (M1) through the multifeeder pick-up clutch (CL2).
3. OPERATIONS AND TIMING 2. Detecting the Size of Copy Paper in the Multifeeder ■ Detecting the Width of Paper The width of copy paper is detected by the variable resistor (VR1751) operating in conjunction with the movement of the slide guide. The slide guide settings are registered when the user makes adjustments for the copy paper set on the multifeeder tray. ■ Rear/Front Registration The rear/front registration for pick-up in the multifeeder is by adjusting the screw on the slide guide.

3. OPERATIONS AND TIMING H. Making Overlay Copies 1. Outline Figure 3-628-1 shows the paper path used to make overlay copies. Copy paper that has moved through the fixing assembly is sent to the lower feeding assembly by the movement of the paper deflecting plate*. In the lower feeding assembly, the set-back roller puts the incoming sheet in a staggered stack and waits for the next sheet.
3. OPERATIONS AND TIMING 2. Sequence of Operations (overlay copying) Copy paper is discharged of sent to the lower feeding assembly by switching the feeding path by the paper deflecting plate 1. The feeding patch is witched by turning ON and OFF the paper deflecting plate 1 solenoid 1 (SL5).

3. OPERATIONS AND TIMING I. Making Two-Sided Copies 1. Outline Figure 3-629 shows the paper path used when making two-sided copies. For the first side of a two-sided copy, the copy paper is moved to the delivery side once after it has been moved through the fixing assembly. When the copy paper moves past the delivery sensor (PS7), the delivery roller reverses after a specific period of time*.
3. OPERATIONS AND TIMING 2. Sequence of Operations (two-sided copying) When copying on the first side of a two-sided copy, copy paper is first fed to the delivery assembly; after a specific period of time, the delivery roller is rotated in reverse to move the paper to the lower feeding assembly. The delivery roller is rotated in reverse a specific period of time after the leading edge of copy paper has moved past the delivery sensor.
3. OPERATIONS AND TIMING J. Lower Feeding Assembly 1. Outline The sheets of copy paper moved to the lower feeding assembly for two-sided/overlay copying are stacked in a staggered pattern by the set-back method and re-picked up for copying on the second side. In the set-back mechanism, sheets of copy paper are stacked in a staggered pattern so that double feeding may be avoided within limited space.

PS12 3) If the copy paper is A4 or larger, SL4 operates the flapper to prevent the copy paper from moving to the re-pick up roller.
3. OPERATIONS AND TIMING 4) The set-back rollers are rotated in reverse to move and stop the copy paper to and at a specific position. PS12 Specific distance Copy paper Set-back rollers Re-pick up roller 5) The 2nd copy paper is fed to the lower feeding assembly. PS12 2nd copy paper 1st copy paper Set-back rollers Re-pick up roller 6) The copy paper is moved in the same way the 1st copy paper was moved.

3. OPERATIONS AND TIMING b. Re-Pick Up Operations (copying on the 2nd side) The sheets of copy paper stacked in the lower feeding assembly after copying on the first side are picked up by the re-pick up roller for copying on the second side. 1) When stacking is over, the set-back roller is moved clockwise, and the copy paper is moved until the re-pick up sensor (PS11) detects the leading edge.
3. OPERATIONS AND TIMING 3. Rear/Front Registration a. Outline • The sheets of copy paper in the lower feeding assembly are picked up without alignment for rear/front direction, requiring detecting of a rear/front displacement while being fed. The rear/front registration detection mechanism is used for sheets picked from the lower feeding assembly.
3. OPERATIONS AND TIMING b. Operations The home position of the horizontal registration sensor (PS14) is checked when 24 VDC is supplied (i.e., when the front cover is closed after power-on), and the movement is started when paper is stacked in the lower feeding assembly at detection start position.
3. OPERATIONS AND TIMING Figure 3-636 and Table 3-612 show the electrical parts associated with rear/front registration detection.
3. OPERATIONS AND TIMING c. Adjusting Horizontal Registration (service mode) Adjust the horizontal registration in ‘RSID-SNSHP’ (4th screen) of ‘ADJUST’ in service mode (*3*) if a discrepancy occurs in rear/front direction during pick-up for copying on the second side of an overlay/twosided copy. In this adjustment, the position of the horizontal registration sensor electrically stored in memory is shifted, thereby moving the position of laser exposure.
3. OPERATIONS AND TIMING K. Fixing/Delivery Assembly 1. Outline The drive roller of the fixing assembly is driven by the main motor (M1). When the drive roller rotates, the fixing film rotates, thereby rotating the lower fixing roller. Part of the inner side of the fixing film is heated by the fixing heater. The temperature of the fixing heater is checked by the thermistor (TH1), and the result is sent to the microprocessor on the DC controller PCB as the fixing heater temperature detection signal (TH1).
3. OPERATIONS AND TIMING 2. Controlling the Temperature of the Fixing Heater The fixing heater is turned OFF during standby. To prevent fixing faults caused by low temperature, either of the following five types of temperature control is executed depending on the temperature of the fixing heater (output of the main thermistor TH1) at power-on and the count of copies to be made. a.
3. OPERATIONS AND TIMING ■ Control r 1st to 30th copy 31st to 40th copy 41st to 50th copy 51st to 100th copy ■ Control t 1st to 40th copy 41st to 50th copy 51st to 100th copy → → → → c. If the temperature is 140°C or more at copy start, control is exerted so that the temperature will be 180°C at all times. 1st to 100th → 180°C 205°C 200°C 190°C 180°C → 195°C → 190°C → 180°C b.
3. OPERATIONS AND TIMING 3. Controlling the Supply Power to the Fixing Heater The temperature of the fixing heater is controlled by controlling the power supplied to the fixing heater. The plane-shaped heater used for the fixing heater tends to be subject to variation because of production factors. In view of this, you must enter the resistance in service mode (*3*) whenever you have replaced the fixing assembly so that the microprocessor on the DC controller PCB executes appropriate power control.
3. OPERATIONS AND TIMING 4. Detecting Overheating on the Fixing Heater End 5. Protection Mechanisms The rear end of the fixing heater is equipped with a sub thermistor (TH2) to check for overheating. This is to prevent overheating and consequent damage to the fixing film which could occur when continuous copying is performed using copy of B4 or smaller in size. (Overheating tends to occur where the drum is not in contact with paper.
3. OPERATIONS AND TIMING 6. Correcting the Displacement of the Fixing Film a. Outline As rotation continues, the fixing film tends to become displaced to the front or the rear. To correct such displacement, the machine has a fixing film displacement correction mechanism. The correction is by the fixing film sensor (PS2) for detecting the position of the fixing film motor (M5) for correcting the position of the film. Caution: The lower roller is released when the front door is open.
3. OPERATIONS AND TIMING The fixing film sensor (PS2) is located at the edge of the film to detect the position of the fixing film. The rear (sensor side) of the fixing film has a notch as shown in Figure 3-643 so that the fixing film sensor repeats turning ON and OFF. Normally, the sensor remains ON and OFF for the same period of time when the fixing film is centered.
3. OPERATIONS AND TIMING b. Controlling the Fixing Film Motor The fixing film motor is a stepping motor rotated by pulse signals A, A*, B, B*. DC controller PCB +24V 109-8 109-9 109-10 A 109-11 A* CPU I/O M6 109-12 B 109-13 B* Figure 3-646 COPYRIGHT © 1996 CANON INC. CANON GP215/200 REV.
3. OPERATIONS AND TIMING 7. Locking the Fixing Assembly The locking between the film and the lower roller of the fixing assembly is designed to be released when the front door is opened. Operating the machine with the front door open for servicing work and, therefore, with the fixing unlocked can displace the film. For this reason, you must always lock the fixing assembly as follows if you need to operate the machine with its front door open.
3. OPERATIONS AND TIMING L. Delivery Assembly 1. Outline The machine allows the selection of either of two delivery modes in user mode/service mode. a. Face-Up Delivery In this mode, copies are delivered with the copied sides up (e.g., when delivering one-sided copies or delivering two-sided copies after copying on the second side). Initially, face-up delivery mode is selected regardless of the selected copying mode. b. Face-Down Delivery In this mode, copies are delivered with the copied sides down (e.g.
3. OPERATIONS AND TIMING 1) When the leading edge of the last copy reaches the fixing paper sensor (PS7), the paper deflecting plate 1 solenoid (SL5) turns ON to move the copy paper to the lower feeding assembly. SL5 PS13 2) When the leading edge of the last copy reaches the lower feeding assembly inlet paper sensor (PS12) and a specific period of time passes, the lower feeding assembly inlet motor (M7) starts to rotate in reverse.

3. OPERATIONS AND TIMING M. Detecting Jams 1. Outline As many as seven paper sensors (Figure 3-655) are used to check whether copy paper is moving properly or to check for jams. The microprocessor on the DC controller PCB runs checks at such times as programmed in advance in reference to the presence/absence of paper at specific sensors. When it detects a jam, it will turn OFF the main motor and indicate the Jam message on the control panel.
3. OPERATIONS AND TIMING 2. Types The microprocessor identifies jams in the following conditions: a. Delay Jam Copy paper does not reach the appropriate sensor within a specific period of time, i.e., the sensor does not turn ON. b. Stationary Jams Copy paper does not move past the appropriate sensor within a specific period of time after the sensor detected the paper, i.e., the sensor does not turn OFF. c. Residual Jam Paper remains over a sensor at power ON, i.e., the sensor detects paper.
3. OPERATIONS AND TIMING b.
