It is necessary to replace the following parts of the Multi Bypass Tray with ones provided with the Multi Bypass Attachment Kit in order to match the feed speed of the vacuum feed LCIT.

Around the Paper Feed Motor/ Paper Transport Motor

[A]: Timing Belt x2

[B]: Pulley Gear

[C]: Timing Pulley

Around the Relay Motor

[A]: Timing Pulley

[B]: Timing Belt

Around the Paper Feed Motor and Paper Transport Motor

  1. Bypass tray rear cover [A] (cap x 1,x3)
  2. Disconnect the lift motor [A] with the bracket (x3,x1).

  3. While pushing the motor coupling [A], carefully remove the motor.

    • The tray may fall suddenly when the coupling comes off the shaft, so work carefully.

  4. Remove the transport motor fan [A] with the bracket (x1,x1).
  5. Open the clamps and then free the harnesses (x8).
  6. Disconnect the paper height sensor connectors (x3).
  7. Disconnect the ground wire (x1).

  1. Disconnect the connectors from the bypass tray PCB [A] (x8).

    • It is not necessary to disconnect the connector [B].

  2. Loosen the six screws, three above [A] and three below [B], on the paper feed motor and paper transport motor to release the tension on the timing belt (x6).
  3. Disconnect the paper height sensor [A] (x3).
  4. Remove the timing belt [A] from the paper transport motor.
  5. Remove the timing belt [B] from the paper feed motor.
  6. Disconnect the motor-PCB bracket (x6).
  7. Remove the bracket.
  8. Replace the pulley gear and timing pulley with the ones provided with the Multi Bypass Attachment Kit (pulley gear [A], timing pulley [B]) (x1 each).
  9. Set the two timing belts: M134 [C] temporarily.
    Timing belts: M134 are also provided with the Multi Bypass Attachment Kit.
  10. Re-attach the motor/PCB bracket (x6).
  11. While sliding the motors, re-attach the timing belts to the paper feed and paper transport motors, and then fasten them (x6).
  12. Re-attach the removed parts and connectors.
    • When re-attaching the lift motor, insert the pin [B] of the tray shaft into the dent [A] in the coupling.
    • Moving the sensor shutter [C] while lifting the tray makes the tray shaft rotate. That makes it easy to insert the pin into the dent.

Around the Relay Motor

  1. At the rear, open the clamps and then free the harnesses (x8, x1).
  2. Harness bracket [A] (x3)

  3. Relay motor assembly [A] (x3,x1)

    • Be careful not to drop the bushing.

  4. Replace the timing pulley and timing belt with the ones provided with the Multi Bypass Attachment Kit (timing pulley: transport [A], timing belt: M96 [B]) (x1).
  5. Re-attach the relay motor assembly and then attach the timing belt to the relay motor.
  6. Fix the relay motor assembly (x6).
  7. Re-attach the harness bracket and harnesses.
