2.3 Scanning Section 2.3.1 ADF Section When a document is placed into the document feeder, Document Sensor 1 (DS1) is activated and you will hear the short beep. The width of document is detected by DB4 and DA3 sensors and length of document is detected by DADFA3 and DADFLEG sensors. Document separation is the process that allows a multi-page document to go through the scanner one page at a time. Separation occurs through the action of the separator roller and retard roller.
2.3.2 FBS section • Light reflected from the original passes through three mirrors and a lens to form a reduced image on the CCD Sensor as the Scanner is moved by the Scanner Motor. The CCD sensor converts the light pattern (image data) into an electrical image signal. • The electrical image signal is then output to the Main Board. 1. Exposure Lamp 3. FBS Motor 5. CCD Board (CCD) and Lens 7. B4 sensor 9. Mirrors Carriage A 11. Scanner Home Position Sensor 13. Mirrors Carriage B 2.
2.3.2.1 Exposure Section: Construction and Function 1 Reflector Tape When a book or other bound original is copied, the paper in the area near the binding generally fails to come flush against the glass, so that the copy of these areas is generally too dark. The Reflector Tape reduces this problem by reflecting light from the Exposure Lamp onto these areas of the original. 2 Exposure Lamp A fluorescent lamp is used to illuminate the original.
2.3.2.3 Original Size Detection Timing The copier CPU affirms and resets the readings of the original size at the following timings. • Takes size readings: When the BIS sensor is deactivated. • Affirms size readings: When the Start key is pressed with the BIS sensor activated or the APS sensor deactuated. • Resets size readings: When the APS sensor is deactuated.
2.3.2.4 Mirror Carriage A and Mirror Carriage B Moving Mechanism • During a scan, the Mirror Carriage A projects an even amount of light from the Exposure Lamp onto the entire surface of the original. The light is reflected from the original to the Mirror A of the Mirror Carriage A and then to the Mirror B and Mirror C of the Mirrors Carriage B. • The Mirror Carriage A is driven by the FBS Motor and front and rear Scanner Drive belts.

2.4.2 Image Processing 1. PC Drum • The drum is an aluminum cylinder coated with photosensitive material on which an electrostatic latent image is produced. 2. Drum Charging • A scorotron charger employing a comb electrode generates a negative DC charged layer on the surface of the PC Drum. 3. Photoelectric Conversion Section • The Exposure Lamp directs light onto the original.
2.4.3 Drive System B A A. I/C Motor (M1) Drives the I/C Unit (Drum cartridge). B. Main Motor (M2) Drives the Paper Take-Up Roll, Manual Feed Paper Take-Up Roll, Synchronizing Roller, Image Transfer Roller, and Fusing Unit.
2.4.4 Imaging Cartridge (I/C) • This machine employs an Imaging Cartridge (“I/C” in this manual) that contains a PC Drum, PC Drum Charge Corona, Developing Unit, and Cleaning Unit as one unit.
2.4.4.1 I/C Drive Mechanism • Drive from the I/C Motor is transmitted via a gear train to the PC Drum and Hopper. PC Drum Driver Gear I/C Motor (M1) Hopper Drive Gear Electrical Component M1 Control Signal PJ16A-3 See block diagram of the printer. ON OFF L H 2.4.4.2 Identification and Life of I/C • When the Start key is pressed or the Side Cover is opened and closed, the machine determines whether the I/C is new or one which has been used previously.
2.4.5 PC Drum • The PC Drum used in this machine is the organic photoconductor (OPC) type. The drum consists of an aluminum base coated with a charge generation layer and a charge transport layer. Handling Precautions Prolonged exposure to light can cause the photoconductor surface of the drum to suffer light fatigue, resulting in a loss of photosensitivity. If the I/C is removed from the machine, it should be wrapped in a soft, clean, opaque cloth or other protective covering to prevent exposure to light.
2.4.6 Drum Charging • A scorotron charger system generates a negative DC corona discharge onto the PC Drum surface. The grid mesh ensures uniform charging. • The grid voltage (Vg) applied to the grid mesh is controlled by the constant voltage circuitry within the High Voltage Unit. It is varied through image stabilization control. • To restrict ozone production, the machine uses a PC Drum Charge Corona with a comb electrode.
2.4.7 Erase Lamp • Any potential remaining on the surface of the PC Drum is neutralized by both light from the Erase Lamp and a DC negative voltage applied by the Charge Neutralizing Sheet. • The Charge Neutralizing Sheet applies a negative charge on the surface of the PC Drum which is positively charged by the Image Transfer Roller. A voltage of -820V is applied to the Charge Neutralizing Sheet from the High Voltage Unit. The Erase Lamp then illuminates the surface of the PC Drum to further neutralize it.
2.4.8 PH Section • Based on the image data output from the MFB Board, the LD (laser diode) is activated and the corresponding light strikes the surface of the PC Drum.
2.4.8.1 PH Components 5 4 6 3 2 1 7 1. Polygon Motor (M10) 3. SOS Mirror 5. Laser Diode Board (PWB-B) 7. f-θ Lens Electrical Component M10 2. Cylindrical Lens 4. Collimator Lens 6. SOS Sensor Control Signal PJ8A-3 See block diagram of the printer.
2.4.8.2 Laser Emission Timing (SOS Signal) • The signal output from the Master Board triggers the firing of the laser. The laser beam travels to the Polygon Mirror, lens, and SOS Mirror to eventually hit the SOS Sensor, which generates an SOS signal. • The SOS signal determines the laser emission timing for each line in the main scanning direction.
2.4.9 DEVELOPING UNIT • The Toner Conveying Rollers mix the toner and carrier particles together and carry the toner/carrier mixture up to the Sleeve/Magnet Roller. The magnetic brush formed on the surface of the roller allows the toner to come into contact with the charges on the surface of the PC Drum, thus forming an electrostatic latent image. 1 2 3 4 5 6 14 7 8 9 13 1. Spent Toner Recycling Coil 3. Spent Toner Feed Roller 2 5. Spent Toner Feed Roller 1 7. PC Drum Protective Shutter 9.
2.4.9.1 Sleeve/Magnet Roller • This machine employs the MT-HG system with a Sleeve/Magnet Roller having the following magnetic characteristics. • Turning of the sleeve surrounding the Magnet Roller ensures that fresh developer from the Developer Mixing Chamber is always being conveyed to the point of development with respect to the PC Drum.
2.4.9.2 Developing Bias • The amount of toner attracted onto the surface of the PC Drum is controlled by varying the developing bias voltage. • As the PC Drum deteriorates and its photoconductive layer begins to wear, it becomes more sensitive to the increase in the amount of toner. As a countermeasure against this problem, the developing bias voltage is automatically switched according to the PC Drum temperature, thereby stabilizing the image quality level.
2.4.9.3 ATDC Sensor • The ATDC Sensor automatic adjustment is made when a new I/C is installed in the machine. Toner replenishing control is thereafter controlled as detailed in the following. 1. ATDC Sensor Automatic Adjustment • The ATDC Sensor is automatically adjusted when a new I/C is loaded in the machine. During this sequence, the machine reads the sensor output value and sets it as the reference. This reference value is stored in memory and used until the I/C reaches its service life. 2.
2.4.9.4 Sub Hopper Toner Replenishing Mechanism • Toner is replenished from the Sub Hopper to the Developing Unit by turning the Sub Hopper Toner Replenishing Motor for the period of time controlled by the ATDC output voltage (T/C). Sub Hopper Sub Hopper Toner Replenishing Motor (M7) Electrical Component M7 Control Signal PJ11A-8A See block diagram of the printer.
2.4.9.5 Sub Hopper Toner Empty Detecting Mechanism • A toner-empty condition in the Sub Hopper is detected by the Magnet Lever that moves up and down as the Sub Hopper Toner Agitating Lever turns and actuates and de-actuates the Sub Hopper Toner Empty Switch. • While the amount of toner in the Sub Hopper is more than the predetermined amount, the Magnet Lever rests on the toner, keeping the Sub Hopper Toner Empty Switch de-actuated even when the Sub Hopper Toner Agitating Lever turns.
2.4.9.6 Main Hopper Toner Replenishing Mechanism • When a toner-empty condition in the Sub Hopper is detected, the Main Hopper Toner Replenishing Motor is energized to turn the Toner Bottle, thereby supplying toner from the Main Hopper to the Sub Hopper. • The Toner Bottle Home Position Sensor mounted on the coupling ensures that the Toner Supply Port in the Toner Bottle is positioned at the top whenever the bottle is stopped. • The Toner Bottle Cover Sensor detects whether the Toner Bottle Cover is open.
2.4.9.7 I/C Cooling Fan Motor • The I/C Cooling Fan Motor prevents the temperature inside the machine (around the entire I/C) from rising inordinately. IC I/C Cooling Fan Motor (M9) Electrical Component M9 Control Signal PJ18A-10 See block diagram of the printer. ON OFF DC24V L 2.4.9.8 Ozone Fan Motor • Ozone produced by the PC Drum Charge Corona is absorbed by the Ozone Filter from the air being drawn out of the machine by the Ozone Fan Motor.
2.4.10 PAPER TAKE-UP/FEED SECTION Note: For the details of the paper feed cassette (500-Sheet Cassette), see the Section 6 on this service manual. • This machine employs the Multi-Purpose (MP) Cassette whose capacity is about 250 sheets (about 20 sheets for special paper). Paper Size Detecting Board (PWB-I) Paper Take-up Roll Tailing Edge Stop 2.4.10.1 MP Cassette Paper Lifting Plate • The Paper Lifting Plate installed in the MP Cassette is spring-loaded to push the paper stack upward.
2.4.10.2 MP Cassette-in-Position Detection • When the MP Cassette is slid into the machine, the light blocking plate located in the rear of the cassette blocks the Cassette Set Sensor and the machine determines that the MP Cassette has been slid into position. Cassette Set Sensor (PC6) Light Blocking Plate Electrical Component PC6 Control Signal PJ13A-5B See block diagram of the printer.
2.4.10.3 MP Cassette Paper Empty Detection • Two sensors are used in this machine: the Paper Empty Sensor detects a paper-empty condition, while the Paper Near-Empty Sensor detects a paper near-empty condition. Paper Near-Empty Detection: • A paper near-empty condition is detected as the paper is consumed and when the Near-Empty Lever lowers to eventually block the sensor (L). • At this time, the MP Cassette Paper Empty LED starts blinking.
2.4.10.4 MP Cassette Paper Size Detection • The Paper Size Detecting Board detects the length of the paper (FD). • A lever is connected to the Trailing Edge Stop of the cassette and, as the stop is slid to the size of the paper loaded in the cassette, the lever is moved to turn ON and OFF the size detecting switches mounted on the machine side. • The control panel settings are necessary for any paper size other than the following.
2.4.10.5 Paper Take-Up Mechanism • Drive from the Main Motor is transmitted to the Paper Take-Up Clutch (spring clutch) and, by energizing the Paper Take-Up Solenoid, the Paper Take-Up Roll is turned. • The paper separating mechanism employs a Paper Separator Pad.

2. Manual Feed Paper Take-Up Detection • The Manual Feed Paper Take-Up Sensor detects a sheet of paper that is fed via the Manual Bypass Tray. • The size and type of the paper for manual feed are set on the control panel. Electrical Component PC8 Control Signal PJ4A-7B Unblocked H Blocked L 2.4.10.
2.4.11 SYNCHRONIZING ROLLERS • The Synchronizing Rollers of this machine are located inside the Right Door. They are easily accessible for misfeed clearing by just opening the Right Door. 2.4.11.1 Synchronizing Roller Drive Mechanism/Control • The Synchronizing Rollers are turned by the drive from the Main Motor transmitted to the Synchronizing Clutch. • The rollers are started when the Synchronizing Clutch is deenergized.
2.4.11.2 Paper Dust Remover • The Paper Dust Remover is installed so that it makes contact with the Left Synchronizing Roller. It is intended for preventing paper dust from sticking to the surface of the PC Drum. • As the roller turns in contact with the Paper Dust Remover, triboelectric charging occurs, which attracts paper dust from the paper that passes between the two rollers and the dust is, in turn, transferred onto the Paper Dust Remover.
2.4.12 IMAGE TRANSFER AND PAPER SEPARATION Image Transfer • This machine employs an Image Transfer Roller to transfer the image to the paper. The High Voltage Unit applies an image transfer current to this roller. To ensure that image transfer efficiency is stabilized, the image transfer current is automatically varied according to the paper size, paper type, and the B/W ratio of the original.
2.4.13 PC DRUM PAPER SEPARATOR FINGERS • The three PC Drum Paper Separator Fingers fitted to the I/C mechanically separate paper from the surface of the PC Drum to ensure good and positive paper separation. PC Drum Paper Separator Fingers PC Drum PC Drum Protective Shutter Paper Path Center 8.5 cm 2-42 8.
2.4.14 PC DRUM CLEANING • This machine employs a spent toner recycling mechanism. The Cleaning Blade which is held pressed against the surface of the PC Drum scrapes residual toner off the surface. The waste toner is conveyed by Spent Toner Feed Roller 1 and 2 to the Spent Toner Recycling Duct and eventually back to the Developer Mixing Chamber.
2.4.15 FUSING UNIT • The paper, to which the developed image is yet to be fixed, is fed through heated Left and Right Fusing Rollers. The heat and pressure applied at this time fixes the image permanently to the paper. 1. Paper Exit Roller 3. Paper Exit Sensor (PC3) 5. Right Fusing Roller 7. Left Fusing Roller 9.

• The mode that is initiated following the completion of a warm-up cycle varies as detailed below depending on the machine condition and the Fusing Roller temperature at the restart of temperature control. Machine Condition Power is turned ON. Temperature control is interrupted during warm-up. Temperature control is interrupted during mode 1. Temperature control is interrupted during mode 2. Temperature control is interrupted during mode 3.
2.4.16 PAPER EXIT UNIT • The Paper Exit Roller feeds the paper, to which the developed image has been fixed, out of the machine. The Charge Neutralizing Brush touches the surface of the sheet of paper being fed out of the Fusing Unit to neutralize any static charge left on it. This effectively prevents two sheets of paper fed out of the machine from sticking to each other due to static charge.
2.4.17 FUSING COOLING FAN MOTOR • The Fusing Cooling Fan Motor located in the Right Door prevents the temperature of the Fusing Unit Cover and the area above the I/C from rising inordinately. The motor also draws the paper after it has been separated from the PC Drum onto the transport guide to ensure that it is stably and smoothly fed into the Fusing Unit.

Paper Feed Unit Options 6.4.1.6.3 Cassette-in-Position Detection The machine detects that the cassette is slid into position as follows. • The rib on the cassette frame presses the Cassette Set Switch located on the back panel of the machine, allowing the machine to detect that the cassette is slid in. Cassette set switch S1 Rib 6.4.1.6.4 Paper Size Setting (1) Cassette Paper Size Setting • With the Fixed Paper Size Cassette, the paper size is set using the Tech. Rep. Choice function.
Options Paper Feed Unit 6.4.1.6.5 Paper Near Empty Detection • A paper-near-empty condition is detected through the detection of the height of the Paper Lifting Plate. • As the paper stack is consumed during a copy cycle, the Paper Lifting Plate of the cassette is gradually raised by the tension of the Paper Lifting Springs.
Paper Feed Unit Options 6.4.1.6.6 Paper Empty Detection • When the cassette runs out of paper, the actuator for the Paper Empty Sensor drops into the cutout in the Paper Lifting Plate. This unblocks the sensor and the machine detects that the cassette has run out of paper. • When a paper-empty condition is detected, the blinking LED lights up steadily. • As noted earlier, the Paper Lifting Plate is raised at all times by the tension of the Paper Lifting Springs.
Options Paper Feed Unit 6.4.1.6.7 Paper Separating Mechanism • Each cassette has fingers that function to separate the top sheet of paper from the rest of the paper stack at paper take-up. The fingers are fitted to the right front and rear corners of the cassette. When the Paper Take-Up Roll starts turning to take up the top sheet of paper, its turning force is directly transmitted to the top sheet of paper as it is in direct contact with the Paper Take-Up Roll.
Paper Feed Unit Options 6.4.1.6.8 Paper Take-Up Roll • Since the Paper Lifting Plate is raised at all times by the Paper Lifting Springs, paper is wedged in the mechanism when the cassette is slid out of the machine if the Paper Take-Up Roll is round in shape. So the roll is semicircular and the circular part of the roll is positioned on top at times other than take-up. For the purpose of explanation, we call this position of the Paper Take-Up Roll the “retracted” position.
Options Paper Feed Unit 6.4.1.6.9 Paper Take-Up Retry Control To minimize the occurrence of paper misfeed due to a slippery Paper Take-Up Roll, the Take-Up Solenoid is energized a second time if a sheet of paper fails to reach the Take-Up Sensor within a given period of time after it has been deenergized. The control timing is as follows. A misfeed results if the sheet of paper does not reach the Take-Up Sensor even after three paper take-up sequences.

Large Capacity Cassette Options 6.5.1.6 Mechanical Operations 6.5.1.6.1 Vertical Transport Drive Mechanism 1. Vertical Transport Drive Operation • The Vertical Transport Roller is driven by LCC Transport Motor HMOT. • The driving force of HMOT is transmitted via a gear train and Registration Clutch RCL to the Vertical Transport Roller which feeds the paper from Lift 1 or 2 to the machine. • Because of the long paper path from Lift 2 involved, skew tends to occur in the paper fed from Lift 2.
Options Large Capacity Cassette 6.5.1.6.2 Paper Take-Up Mechanism • The paper take-up mechanism takes up a sheet of paper from the paper stack on each lift and feeds it to the Vertical Transport Roller. • A paper take-up sequence is performed when drive from LCC Transport Motor HMOT is transmitted via Take-Up Clutch 1/2 P1CL/P2CL to Paper Take-Up Roll 1/2. When Lift 1 runs out of paper, paper is then fed from Lift 2.
Large Capacity Cassette Options 1. Paper take-up from Lift 1 A. After Lift 1 has completed its lifting motion, Paper Take-Up Roll 1 is driven to take up and feed a sheet of paper until the paper blocks Paper Standby Position Sensor S1. This serves as the standby position of the paper. Registration sensor RSEN Vertical transport roller Paper standby position sensor S1 Paper take-up roll 1 Separator/Feed roll Lift 2 Lift 1 B.
Options Large Capacity Cassette C.The Vertical Transport Roller is driven to transport the paper to the machine. When the trailing edge of the paper being transported by the Vertical Transport Roller unblocks Paper Standby Position Sensor S1, the subsequent sheet of paper is transported to the standby position and the LCC waits for the next Paper Take-Up signal to be received. D.
Large Capacity Cassette Options 2. Paper take-up from Lift 2 A. When all sheets of paper have been taken up and fed in from Lift 1, Lift 1 is placed in the top level position to serve as part of the paper path for paper feeding from Lift 2. B. When the trailing edge of the last sheet of paper from Lift 1 unblocks Paper Empty Sen-sor 1 PPS1, both Paper Take-Up Roll 1 and 2 start turning. C.
Options Large Capacity Cassette E. When a Paper Take-Up signal is received from the machine, the Separator/Feed Rolls and Paper TakeUp Roll 1 are driven to transport the paper up to Registration Sensor RSEN. After RSEN has been blocked, the paper is transported a little further to reach the Vertical Transport Roller, plus form a registration loop, before being brought to a stop. F. The Vertical Transport Roller is driven to transport the paper to the machine.
Large Capacity Cassette Options H.Registration Clutch RCL is deenergized a given period of time after the trailing edge of the paper being taken up has unblocked Registration Sensor RSEN. The next Paper Take-Up signal is transmitted after the timer, which is started as the Vertical Transport Roller starts moving for the preceding sheet of paper, has run out. I. The steps E to H are repeated to transport paper from Lift 2.
Options Large Capacity Cassette 6.5.1.6.3 Paper Take-Up Retry Control To minimize the occurrence of paper misfeed due to a slippery Paper Take-Up Roll, Separa-tor Clutch BCL is energized a second time if a sheet of paper fails to reach Registration Sensor RSEN within a given period of time after BCL has first been energized. The control timing is as follows. A paper misfeed results if the sheet of paper does not reach the Registration Sensor even after three paper take-up sequences. 6.5.1.6.
Large Capacity Cassette Options 6.5.1.6.5 Paper Pressure Releasing Mechanism • The LCC is provided with a mechanism that releases the pressure between the Feed and Separator Rolls and between the paper and Paper Take-Up Roll when the LCC is slid out of the machine. • The pressure between the Feed and Separator Rolls is released by the Separator Roll Assy and the Pressure Release Rail above the rail on the paper take-up end.
Options Large Capacity Cassette 6.5.1.6.7 Edge Guides and Trailing Edge Stop The Trailing Edge Stop is screwed into position (not used for Letter crosswise). Edge Guides can be slid into any desired position. Whenever the positions of the Edge Guides and Trailing Edge Stop have been changed, be sure to perform the paper size setting procedure. (See “Paper Size Setting” that follows.) * The inch area LCC can be set for Letter crosswise only. Trailing edge stops Edge guides 6.5.1.6.

LCC set sensor FRONT 6.5.1.6.10 Lifting Mechanism When the LCC is slid into the machine, the couplings are engaged. When LCC Lift-Up Motor EMOT turns forward and backward, its drive is transmitted via a one-way gear and gear train to raise Lift 1 and Lift 2, in that order.
Options Large Capacity Cassette When LCC is Slid in: LCC Set Sensor FRONT is blocked. LCC Lift-Up Motor EMOT turns forward to raise Lift 1. The paper stack causes the light blocking plate of the Paper Take-Up Roll 1 Assy to block Lift-Up Sensor 1 LS1. EMOT is deenergized and then energized to start turning backward, thereby raising Lift 2. The paper stack causes the light blocking plate of the Paper Take-Up Roll 2 Assy to block Lift-Up Sensor 2 LS2. EMOT is deenergized.

2-Bin/Shift Tray Options 6.6.1.6 Operation Of Each Mechanism 6.6.1.6.1 Paper Transport Mechanism (1) Paper Transport Path A sheet of paper fed out of the machine by the Paper Exit Roller/Rolls of the machine is fed through, and out of, this unit by the unit’s Paper Exit Roller onto the unit’s Exit Tray. Since this unit is mounted directly on top of the machine, Section over the machine Exit Tray, it serves as an upper exit tray.
Options 2-Bin/Shift Tray (3) Control of Transport Motor A two-phase stepping motor is used as Transport Motor. The motor is turned as the pulse signals output from PJ8A-1 to 4 are applied to it. The direction of the motor rotation is switched by changing the output sequence of these pulse signals.
2-Bin/Shift Tray Options 6.6.1.6.2 Full-of-Paper Detecting Mechanism (1) Job Tray • Paper is fed into the Upper Exit Tray or Lower Exit Tray depending on the copy mode. The paper being fed into the tray operates the actuator, which unblocks and blocks the Upper or Lower Full Detecting Sensor to allow the system to detect a full-of-paper condition. (Upper Exit Tray) A full-of-paper condition is detected when the Upper Full Detecting Sensor remains unblocked for a continuous, given period time.
Options 2-Bin/Shift Tray (2) Shift Tray In the Shift Tray, a photointerruptor (PWB-B2, -C2) is used. When light from the PWB-C2 LED is blocked by a sheet of paper being fed out onto the tray, a full-of-paper condition is detected.
2-Bin/Shift Tray Options 6.6.1.6.3 Exit Path Switching Mechanism The paper path is selected by energizing or deenergizing Path Switching Solenoid SL1, which results in the Exit Path Switching Plate being swung down or up.
