Page 442: Print Process Overview
Print Process Overview Print Process Overview DRUM CHARGE In the dark, the charge corona unit gives a negative charge to the OPC drum. The grid plate ensures that corona charge is applied uniformly. The charge remains on the surface of the drum because the OPC layer has a high electrical resistance in the dark.
Page 443 6. Details The magnetic developer brush on the development roller contacts the latent image on the drum surface. Toner particles are electrostatically attracted to the areas of the drum surface where the laser reduced the negative charge on the drum. PTL (Paper Transfer Lamp) The PTL removes the charge on the drum to improve paper separation and prevent pawl marks on the paper.
Page 444: Laser Exposure
Laser Exposure Laser Exposure Overview There are four laser diodes. Four parallel beams write four lines at once, 24 lines with one complete rotation of the polygon mirror, with the polygon motor rotating at 42,756 rpm. This adoption of multi-beam operation achieves: •...

OPC Drum The optical path is a standard arrangement, starting at the LD unit and ending with the creation of the latent image on the OPC drum.
Page 446 Laser Exposure Four-Beam Exposure The LD unit uses four laser diodes to write four lines simultaneously. The diodes are fixed at 1200 dpi, so beam pitch adjustments are not required. The diagonal arrangement of the four beams achieves 1200 dpi. 600 dpi 8-bit write data is converted to 1200 dpi 1-bit digital data during image processing.
Page 447 6. Details Cooling Fan The cooling fan [A] at the back of the machine blows air through the duct [B] and sends it above and below the laser exposure unit. The fan switches on and off with the polygon motor. The air [C] above passes through a dust filter before it reaches the optical path.

Page 450 Drum Unit The PTL removes the charge on the drum. This makes better paper separation. Also, with the PTL, pawl marks do not occur on the leading edges of copies. The PTL only operates when the machine prints on plain or translucent paper. OPC Drum The OPC drum [A] contains ventilation holes [B] to prevent overheating.
Page 451 6. Details The drum motor [A] drives both the OPC drum and the cleaning unit. A flywheel [B] on the drum drive shaft [C] reduces drum vibration. The other drive shaft [D] drives the cleaning unit. The drum drive shaft [C] drives the drum at 362 mm/s.
Page 452 Drum Unit Charge Corona Wire Cleaning Air flowing around the charge corona unit deposits toner particles on the wires. These particles interfere with charging and cause pale bands on copies. The wire cleaner [A] normally remains at the home position at the front end. To clean the wires, the charge corona wire cleaner motor [B] switches on and drives the cleaner [A] to the rear, then back to the home position.
Page 453 6. Details Drum Pick-off Mechanism Pick-off pawls ride along the surface of the drum to peel off paper that has not separated from the drum. Weak spring pressure [A] keeps the pick-off pawls [B] against the surface of the drum. During copying, a shaft [C] turns a cam [D].
Page 454 Drum Unit This machine uses a counter blade and brush system. • The drum cleaning blade [A] contacts the drum, and is angled against the direction of rotation to improve cleaning. • The cleaning brush [B] rotates and removes some toner from the drum, and collects the toner removed by the cleaning blade.
Page 455 6. Details Drum Ventilation and Ozone Filter Cooling prevents uneven buildup of negative ions which can lead to uneven charge on the drum surface. The drum cooling fan [A] draws cool air into the machine and sends it over the charge corona unit [B] and down through the vents in the ends of the drum [C].
Page 456 Drum Unit Toner Recycling The toner collection coil inside the toner recycling pipe [A] carries toner collected from the drum cleaning unit into the toner separation unit [B] (above the toner hopper). Re-usable toner is separated here from old toner. Sieve [C] sifts the toner, and brush [D] inside the sieve moves the toner forward.
Page 457 6. Details Old toner [F] does not fall through the sieve. It is pushed through opening [G] to the toner transport coil [H]. The coil moves the toner towards the back of the machine, where it is deposited in the toner collection bottle.
Page 458 Drum Unit If the toner collection coil sensor [F] (not shown) does not change within 3 seconds after the drum motor turns on, the transport coil is clogged and cannot rotate, then SC495 (Toner Recycling Unit Error) is logged. When the toner overflow switch (not shown) detects that the toner collection bottle [G] is full, operation halts after an additional 100 copies and the machine prompts the user to replace the toner collection bottle.
Page 459 6. Details Any SC codes that are generated during auto process control are logged in the memory and do not appear. The machine will continue to operate. Drum Potential Sensor Calibration The potential sensor output is affected by the distance of the sensor from the OPC, paper dust or other matter on the surface of the sensor, and environmental conditions.
Page 460 Drum Unit 1. The drum motor starts. 2. The grid voltage, development bias, and laser power are set to the default values that would be used if process control was disabled. These are as follows: • Development bias is set to the value stored in SP2201-001 •...
Page 461 6. Details If the ID sensor output cannot be adjusted to the standard, then after 20 seconds SC353 or SC354 is issued. Toner supply during copying will then be controlled using the TD sensor only, until the machine is repaired. TD Sensor Calibration (Vref) Next, Vref (TD sensor reference voltage) is updated using the latest calibration values from the ID sensor.

Page 466 Development and Toner Supply Development power pack [A] applies –550V through terminal [B] to the shaft [C] of the development roller [D]. Bias is also applied to the lower casing to prevent toner from being attracted back from the drum. Toner Supply The ID sensor and TD sensor control toner density.
Page 467 6. Details Development Unit Drive and Ventilation The development motor [A] (a dc motor) drives the following units through three drive shafts: toner sepa- ration unit [B], toner supply unit [C], and development unit [D]. The knob [E] attached to the paddle roller can be rotated in one direction only. Use this knob just after adding new developer, to apply an even coating of developer to the development roller sleeve.
Page 468 Development and Toner Supply Shutter Mechanism When the toner bottle holder is opened, a self-sealing shutter prevents toner spill. The top of the shutter [A] has a semi-circular opening [B]. Normally, toner from the toner bottle [C] flows through this opening into the hopper below. However, pulling out the shutter cover [D] closes the cover automatically to prevent toner spill from the hopper.
Page 469 6. Details Toner Bottle Supply and Ventilation The toner supply motor [A] (a dc motor) and gears [B] rotate the toner bottle [C]. The toner cooling fan [D] (below the operation panel) ventilates the area around the bottle. This fan always switches off and on with the polygonal mirror motor.

Details • SP2507-002 (ID Sensor Interval – Page Setting) is available for customers who are con- cerned about changes in toner density during long copy jobs and may want to specify an interval to force creating and reading the ID sensor pattern. However, enabling this SP will pause copying for 2 or 3 seconds every time the ID sensor pattern is created and read 2.
Page 472 Development and Toner Supply ID sensor pattern creation parameters depend on whether automatic process control is switched on or off with SP3901-001 (Auto Process Control). If automatic process control is switched on: • Charge corona grid voltage: Set automatically for the existing conditions around the drum. •...
Page 473 6. Details • Vt = 0.5 volts or lower • Vt = 4.0 volts or higher Then SC340 (TD Sensor Output Error) is logged. Abnormal ID Sensor Output Abnormal output detected during process control at power-on: SC353 or SC354 is issued. Toner supply during copying will then be controlled using the TD sensor only, until the machine is repaired.

Page 475 6. Details Transfer Belt Lift Mechanism The transfer belt lift solenoid [A] lifts the belt into contact with the drum using the link [B], which is connected to the front [C] and rear [D] belt lift levers. Springs attached to the front of the solenoid reduce the load on the solenoid as it lifts the drum. This mechanism raises the transfer belt unit against the OPC drum only when needed, and keeps it separated at all other times because: •...
Page 476 Image Transfer and Paper Separation Timing [A] Registration roller [B] Transfer belt [C] OPC drum [D] Front and back levers [E] Nip width (about 8 mm) The transfer belt stays away from the OPC drum until 500 ms after the drum motor starts. Then the transfer belt lift solenoid switches on to lift the belt.
Page 477 6. Details • Cleaning Roller: About +1.0 kV max. through terminal [D] to the cleaning roller [E]. Drive rollers [F, G] are grounded so that the cleaning unit can clean the belt easily. Transfer Current Settings Here is a list of the default current settings for each paper feed station. Transfer Current (Initial Val- SP No.
Page 478 Image Transfer and Paper Separation Transfer Current Circuit [A]: Transfer power pack [B]: Transfer roller [C]: Nip between drum and transfer belt [D]: Drive rollers The transfer power pack does the following: • Monitors the currents I1 and I2 • Adjusts its output (It) to keep the current I3 constant, regardless of changes in temperature or humidity which can affect the surface resistance of the paper.
Page 479 6. Details At the turn in the transfer belt, the transfer belt drive roller [C] discharges the belt to reduce paper attraction, and the paper separates from the belt as a result of its own stiffness. The tapered parts [D] at both ends of the roller [E] help keep the transfer belt [F] in the center, so that it does not run off the rollers.
Page 480 Image Transfer and Paper Separation Toner scraped from the cleaning roller drops it onto the agitator plate [D]. The plate [D] moves the toner into the collection coil [E]. The coil takes the toner to the toner collection bottle. Anti-Condensation Heater The anti-condensation heater [A] is directly below the transfer belt drive roller.

Page 482 Paper Feed • The machine has three built-in paper trays: • Tandem LCT (Tray 1). 1550 + 1550 sheets • Universal Tray (Tray 2) 550 sheets • Universal Tray (Tray 3) 550 sheets Built-in Feed Stations • Paper feed and separation. Standard FRR system with a torque limiter for paper separation and feed. Each tray has an independent stepper motor to drive its paper feed mechanisms.
Page 483 6. Details Paper Feed Drive An independent paper feed motor [A] drives the rollers in each tray. It also drives grip rollers [B], which pull the paper out of the tray. The mechanism is identical for each tray. A vertical transport sensor [C] at each feed station detects paper jams. The paper feed motors on the trays drive the vertical transport rollers, which are opposite each feed station (not shown here).
Page 484 Paper Feed Tray and Paper Lift Mechanism – Tray 2,3 Bottom Plate Lift Tray lift motor [A] > Coupling [B] > Pin [C] > Shaft [D] > Lift arm [E] (under the bottom plate). The universal trays (Tray 2, Tray 3) are not provided with near end sensors. The pulse count of the tray lift motor is used to signal near end.
Page 485 6. Details After several paper feeds, the paper level gradually lowers and the lift sensor is de-activated. Then the lift motor turns on again until the lift sensor is activated again. When the tray is drawn out of the feed unit: gear [F] disengages pin [G] on shaft [H], then the tray bottom plate [I] drops by its own weight.
Page 486 Paper Feed Feed roller [A] > No rotation Separation roller [D] > Free to rotate Grip roller [B] > Rotates Paper Feed and Separation If a paper feed station is not selected, its separation roller solenoid [A] stays off and the separation roller [B] can turn freely in the opposite direction to feed paper.
Page 487 6. Details Grip roller > Rotates Separation Roller Release Mechanism Normally, the separation roller [A] and feed roller [B] are not in contact. However, when the feed station is selected, the separation roller solenoid [C] pushes the separation roller against the feed roller. This mechanism has these advantages: •...
Page 488 Paper Feed This mechanism ensures that the feed and separation rollers do not stick together at the start of a job just after the machine leaves standby mode. When the feed roller reverses at the start of the job, a small arm [D] pushes the feed roller slightly forward so that it comes away from the separation roller.
Page 489 6. Details Paper Near-End And Paper End – Trays 2, 3 The machine detects paper near end by counting the number of pulses the motor makes when lifting the bottom plate. The paper end sensor [A] receives light reflected from the paper below [B] until the last sheet has been fed. Then, paper end is detected.
Page 490 Paper Feed Universal Cassettes (Tray 2, 3) The paper size switch [A] detects the paper size with 5 microswitches. The actuator plate [B], attached to the rear of the paper tray, actuates the paper size switch. The output from the sensor depends on the position of the side fences, which affects the sensor output, as shown in the table.
Page 491 6. Details SP5129: The machine can detect 8" x 13" (default), 8½" x 13", or 8¼" x 13". If the switch is set to the asterisk (*), a range of paper sizes (illustrated below) can be selected, but the size must be entered with a UP mode.
Page 492 Paper Feed Tandem Tray – Tray 1 Overview 1,550 sheets of paper can be set in each of the left [A] and right trays [B]. Paper is fed from the right tray. When the paper in the right tray runs out, the paper in the left tray automatically transfers to the right tray. After the paper transfers to the right tray, paper feeding resumes.
Page 493 6. Details Connecting the Left and Right Sides of the Tray When there is paper in the left tray: • Lock lever [A] in the left tray catches the pin [B] in the right tray. During copying, if there is no paper in the left tray: •...
Page 494 Paper Feed When the machine detects that the tray is in the machine, the right tray paper sensor [A] (under the tray) checks whether there is paper in the right tandem tray. • If sensor [A] was not present and the tray was empty, the bottom plate would have to lift until the 1st tray lift paper end sensor (at the top of the tray) detected that there was no paper, and this would waste several seconds.
Page 495 6. Details Paper remaining: The amount of paper remaining in the tray is detected by which combination of the three paper height sensors [A] are actuated by the actuator on the left rail as the bottom plate rises. • With the actuator below paper height sensor 1 (the bottom sensor), no sensor is actuated and the display indicates the tray is full.
Page 496 Paper Feed Fence Drive The side fences [A] of the right tray open only when paper in the left tray goes to the right tray. The side fence solenoids [B] turn on to open the side fences, until the side fence open sensors [C] activate. After the stack has been moved into the right tray: The side fence solenoids turn off to close the side fences, until the side fence close sensors [D] activate.
Page 497 6. Details Rear Fence Drive When the left tray paper sensor [A] detects paper but the right tray paper sensor does not, the following happens. • Rear fence motor [B] (a DC motor, in the left tray) turns counter-clockwise → Rear fence [C] pushes the paper stack into the right tray.
Page 498 Paper Feed Tray Side-to-Side Positioning When the feed tray is set in the paper feed unit, the side-to-side positioning plate [A] presses the feed tray against the stopper [B]. By moving the positioning plate, the tray position can be changed to adjust the side-to-side registration.
Page 499 6. Details Paper Registration Overview The registration rollers [A] and registration sensor [B] handle paper fed from four directions: • Tandem tray and universal trays below [C] • Duplex unit [D] • Optional LCT [E] The grip rollers [F] feed paper from the trays into the vertical transport path to the registration rollers. The upper relay roller [G] feeds all paper exiting the vertical transport path.
Page 500 Paper Feed Paper Registration Drive When the registration sensor [A] detects the leading edge of the paper, the registration motor [B] stops the paper at the registration rollers [C, D] for a short while to correct the skew in the paper. Mylar [E] touches the upper surface of roller [C].
Page 501 6. Details If a paper misfeed occurs between the vertical transport rollers and the registration rollers, the next sheet is already on its way up from the paper tray, and must be stopped, or there will be a pile-up of jammed paper.

Page 503 6. Details The center thermistor (1) (not in direct contact with the hot roller) controls the temperature at the center of the hot roller. The end thermistor (3) directly contacts the hot roller surface and prevents overheating. The two thermostats (2) also prevent overheating. The web cleaning unit (web roller, cleaning roller, and take up roller) applies a light coat of silicone oil to the hot roller to prevent toner and paper dust from sticking to the hot roller.
Page 504 Image Fusing and Paper Exit If the thermostats trigger an alert, the thermostat requires replacement. A fusing exit sensor, located between the hot roller and paper exit roller, detects paper jams inside the fusing unit. Pressure Roller Heavy springs [A], attached to pressure arms [B] below both ends of the pressure roller [C], keep the roller pressed against the hot roller [D] above.
Page 505 6. Details Hot Roller Cleaning The cleaning web is saturated with silicone oil. Inside the web cleaning unit, the web take-up roller [A] pulls the web from the web supply roller [B] past the cleaning roller [C]. The cleaning roller is pressed against the hot roller. Web Drive The web motor drives the web supply roller [A] and web take-up roller [B].
Page 506 Image Fusing and Paper Exit When all of the web has been used (after about another 30k copies), the actuator rotates, its feeler actuates the web end sensor, and SC550 (Fusing Unit Web End) is logged. After replacing the web with a new one, reset SP1902-001 to 0 to release SC550.
Page 507 6. Details Fusing Unit Drive Fusing/exit motor [A] > timing belt [B] > gear coupling [C] > fusing unit Inserting the fusing unit engages the coupling [C]. The pressure roller [D] is driven by friction between the pressure roller and the hot roller [E]. The fusing unit exit rollers [F] are driven through some gears.
Page 508 Image Fusing and Paper Exit The thermistor contacting the center of the hot roller surface monitors the temperature of the hot roller. The CPU turns the fusing lamps on and off to keep the hot roller surface at the target temperature. The target temperature depends on the paper type.
Page 509 6. Details Here is a list of SC codes issued if a fusing unit error occurs. For details, see “Troubleshooting”. SC541 Fusing thermistor open SC542 Fusing temperature warm-up error SC543 Fusing lamp overheat error 1 (software)
Page 510 Image Fusing and Paper Exit SC544 Fusing lamp overheat error 1 (hardware) SC545 Fusing lamp overheat error 2 • To release the machine after one of these SC codes is issued, just enter the SP mode. Paper Exit Fusing/exit motor [A] > timing belt [B] > exit roller [C] via gears and timing belts. The de-curler rollers [D] remove curl from the paper before it exits.
Page 511 6. Details Exit Junction Gate The exit junction gate [A] is controlled by the exit junction gate solenoid [B]. • If the solenoid is on: The gate opens, and paper [C] goes straight through [D] to the output tray (for face-up delivery) or the finisher.
