  • Page 48: Paper Near Empty Detection

    4023-001 Paper Near Empty Detection Height of the paper lifting plate determines paper-near-empty condition. Since the amount of paper available during the take-up sequence varies, detection occurs when the paper take-up roll is in the retracted position. 1-22 Service Manual...

  • Page 49: Paper Empty Detection

    4023-001 Paper Empty Detection When the cassette runs out of paper, the actuator of the paper empty sensor drops into the cutout of the paper lifting plate. This exposes the sensor, signaling that the cassette is out of paper. 1-23 General Information...

  • Page 50: Paper Separating Mechanism

    4023-001 Paper Separating Mechanism Each cassette has fingers that separate the top sheet of paper from the rest of the paper stack during paper take-up. When the paper take-up roll starts to turn, the turning force transmits to the top sheet of paper.

  • Page 51: Paper Take-Up Roll

    4023-001 Paper Take-Up Roll Two paper take-up rolls are mounted in both the fixed paper size cassette and universal cassette. As the take-up solenoid energizes, the spring tension increases, meshing the drive and clutch gear which transmits drive to the paper take-up rolls. 1-25 General Information...

  • Page 52: Paper Feed

    4023-001 Paper Feed The paper taken up by the paper take-up section feeds to the transfer section after registration compensation. Registration Compensation Registration compensation eliminates paper skew by controlling the paper take-up roller and synchronizing roller rotation timing. The taken-up paper passes the synchronizing roller sensor (PC2) and reaches the synchronizing roller.
  • Page 53 4023-001 The synchronizing roller feeds paper to the PC drum and transfer roller. The PC drum and transfer roller pinch the paper and feed it to the fusing section. PC Drum 4 Synchronizing Clutch (CL1) Image Transfer Roller 5 Paper Transport Roller 6 Synchronizing Roller 1-27...

  • Page 54: Printhead Unit (Exposure Section)

    4023-001 Printhead Unit (Exposure section) The printhead unit incorporates a laser diode that emits a laser beam corresponding to the print image data. The scanning laser beam scans the PC drum from left to right, producing an electrostatic latent image on the surface of the PC drum.

  • Page 56: Development Section

    4023-001 Development Section Development The development section feeds toner to the electrostatic latent image on the surface of the PC drum to produce a visible toner image. A screw circulates the toner in the toner hopper. The toner mixes with the carrier to produce the developer. The ATDC sensor detects the ratio of toner to carrier, and voltage controls the toner density.

  • Page 58: Toner Empty Detection

    4023-001 Toner Empty Detection Three empty-toner conditions are detected: sub-hopper empty, toner bottle near empty, and toner bottle empty. Sub-Hopper Empty The toner detection plate lead switch checks the toner level by detecting the position of the toner detection plate. The toner bottle supplies toner to the rotating mixing plate.
  • Page 59 4023-001 Toner bottle near empty The toner bottle empty status is detected when the toner bottle rotates and feeds toner to the sub-hopper. The bottle rotation counter checks the number of bottle rotations. If the number of rotations exceeds 10, the near empty status occurs. The bottle supplies toner after the near empty status occurs.

  • Page 60: Image Transfer Section (Release Section)

    4023-001 Image Transfer Section (Release Section) The transfer roller transfers the toner image on the surface of the PC Drum onto the paper. Normally the paper separates from the PC drum without any outside interference. When the paper fails to separate from the PC drum, the separating claw releases the paper by force.

  • Page 61: Optical Erase

    4023-001 Optical Erase During the optical erase, light from the eraser lamp irradiates the PC drum, eliminating the negative charge applied by the cleaning blade during PC drum cleaning. This prevents black lines from being created on the front and rear ends and both sides of the image. Cleaning Blade Optical Erase 1-35...

  • Page 62: Fusing Section

    4023-001 Fusing Section Fusing Toner-transferred paper feeds from the transfer section to the fusing section when power from the transport motor (M2) transmits to the upper fusing roller. The fusing roller heater lamp (H1, built in the roller) heats the upper fusing roller.

  • Page 63: Fusing Temperature Control

    4023-001 approximately 220°C, the contact of the thermostat automatically opens to shut off AC voltage. (As the temperature decreases, the contact of the thermostat closes again. However, once the thermostat activates, you must replace it with a new one.) The thermostat cannot respond quickly enough to protect against a sudden overload current.

  • Page 64: Paper Exit Section

  • Page 72 4023-001 from lift 2. To correct skew, RCL forms a loop in the paper between the separator roll and vertical transport roller. Control of LCC Transport Motor HMOT The printer main engine board energizes and de-energizes HMOT by sending signals to HMOT through the LCC (paperdeck) main board (PWB-A).

  • Page 73: Paper Take-Up Mechanism

    4023-001 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 occurs when drive from LCC Transport Motor HMOT transmits through take-up clutch 1/2 P1CL/P2CL to paper take-up roll 1/2.
  • Page 74 4023-001 Paper Take-Up From Lift 1 After Lift 1 completes lifting motion, paper take-up roll 1 takes-up and feeds a sheet of paper until the paper blocks paper standby position sensor S1. This serves as the standby position of the paper. When the printer sends a paper take-up signal, the separator/feed rolls and paper take-up roll 1 transports the paper up to registration sensor RSEN.
  • Page 75 4023-001 little further to reach the vertical transport roller, and forms a registration loop, before stopping. The vertical transport roller transports the paper to the printer. 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.
  • Page 76 4023-001 Paper Take-Up From Lift 2 After all sheets of paper have been taken up and fed from lift 1, lift 1 moves to the top level position to serve as part of the paper path for feeding paper from lift 2. After the trailing edge of the last sheet of paper from Lift 1 unblocks paper empty sensor 1 PPS1, both paper take-up roll 1 and 2 turn.
  • Page 77 4023-001 After the printer sends a paper take-up signal, the separator/feed rolls and paper take-up roll 1 transports the paper until the paper blocks registration sensor RSEN. The paper travels a little further to reach the vertical transport roller and form a registration loop before stopping.

  • Page 78: Paper Take-Up Retry Control

    4023-001 If PPS0 is unblocked and a sheet of paper is blocking PPS1, the sheet of paper blocking PPS1 transports to the standby position uninterrupted. LCC then waits for the next paper take-up signal. Registration clutch RCL de-energizes a given period of time after the trailing edge of the paper being taken-up unblocks registration sensor RSEN.

  • Page 79: Paper Separating Mechanism

    4023-001 Paper Separating Mechanism The paper separating mechanism employs a system with a torque limiter that is fitted to the separator roll shaft. It stops the separator roll when friction changes between the feed and separator rolls. Paper Pressure Releasing Mechanism When LCC is pulled out, the pressure release rail pushes the separator roll assembly downward, releasing the pressure between the feed and separator roll.

  • Page 80: Paper Take-Up Roll Retracting Mechanism

    4023-001 Paper Take-Up Roll Retracting Mechanism When LCC is slid out, the projection on the back of the LCC front cover disengages from the pressure release lever. This pushes the paper take-up roll upward, releasing pressure between the paper and paper take-up roll. Edge Guides and Trailing Edge Stop The trailing edge stop screws into position (not used for letter crosswise).

  • Page 81: Paper Size Setting

    4023-001 Paper Size Setting The paper sizes that can be set are A4 crosswise and Letter crosswise. After the positions of the edge guides and trailing edge stop change, place the DIP switch keys on LCC main engine board PWB-A in the corresponding positions according to the current paper size Note: Positions 3 and 4 are not used.

  • Page 82: Lcc-In-Position Detection

    4023-001 LCC-in-Position Detection The LCC is detected at its closed position when the light blocking plate located on the rear end of the right rail blocks LCC Set Sensor FRONT. Lifting Mechanism When the LCC is slid into the printer, the couplings engage. The LCC lift-up motor EMOT rotates forward and backward, turning the one-way gear and gear train to raise Lift 1 and Lift 2 respectively.

  • Page 83: Lifting Operations

    4023-001 Lifting Operations LCC set sensor FRONT is blocked. LCC lift-up motor EMOT turns forward raising lift The paper stack causes the light blocking plate o the paper take-up roll 1 assembly to block lift-up sensor 1 LS1. EMOT de-energizes and then energizes to start turning backward, raising Lift 2.

Lift 1 and 2 ascends. • LCC is slid into position. • The lift-up sensor is unblocked while a paper take-up sequence occurs with paper present on the lift.

  • Page 85: Paper Near Empty Detection

    4023-001 Paper Near Empty Detection A paper-near-empty condition is detected by sensing the height of lift 1 or lift 2. When paper is used during a print cycle, lift 1 or 2 gradually moves up. This eventually unblocks the paper near empty sensor, indicating that the LCC (paper deck) is near empty.

  • Page 86: Paper Dehumidifying Heaters

    4023-001 ² When Paper is Not Loaded The light from the LED of paper empty sensor 1 PPS1 or paper empty sensor 2 PPS2 does not reflect, indicating there is no paper loaded in the LCC. Paper Dehumidifying Heaters Paper dehumidifying heaters (mounted on both sides of the LCC) prevent paper passage performance from being degraded by damp paper during highly humid conditions.
