• Turn the machine off and disconnect the machine power cord before you do this procedure.

MP C6503/C8003: Start from step 1.

Pro 5200S/5210S: Start from step 11.

  1. Remove the rear middle cover.

    Check the positions of the bosses and hooks before removing the cover.

  2. Remove the rear lower cover.

    Check the positions of the bosses before removing the cover.

  3. Remove the cover [A].
  4. Attach the connector [A] of the harness provided with the cooling fan unit.
  5. Connect the harness provided with the copy tray [A] to the connector, and then clamp the harness.
  6. Connect the harness [A] to CN272 of the PFB.
  7. Clamp the harness [A].
    Pass the harness under the black tubes.
  8. Remove the connector cover [A] from the rear middle cover
  9. Reattach the rear lower cover.
  10. Reattach the rear middle cover.
  11. Open the drawer unit [A].
  12. Attach the sheet [A] to the left side of the drawer unit.

    There are four cutouts in the sheet.

    Align the left-most cutout with the corner [A] of the paper exit.

  13. Attach the paper height sensor [A] and harness clamp [B] to the sensor bracket [C].
  14. Attach the actuator [F] to the actuator arm bracket [D].
  15. Attach the actuator bracket [D] to the sensor bracket [C]. (M3 x 6)
  16. Connect the sensor harness [E] to the sensor [A].
  17. Attach the sensor bracket [C] to the main machine. (M4 x 12)
  18. To make it easier to remove the left middle cover [A], remove the screws from the rear middle cover [B] and the rear lower cover [C].
  19. Remove the screws of the left middle cover [A].
  20. Hold the positions shown below and pull the left middle cover [A] toward you to remove it.
  21. Make four holes [A] in the left middle cover with a screwdriver.

  22. Reattach the left middle cover.
  23. Pro C5200S/C5210S only: Remove the connector cover [A].
  24. Attach the copy tray [A].

    • Remove the retainer from the copy tray before attaching the tray.

  25. Install the cooling unit [A] on the cooling unit bracket [B]. (hook x2)
  26. Fasten the cooling unit to the cooling unit bracket. (M3 x 6)
  27. Install the cooling unit bracket [A] on the left side of the main machine. (M4 x 20)
  28. Attach the cable clamp [A] provided with the copy tray to the main machine. Then route the harness as shown below.
  29. Connect the interface cable of the cooling unit [A].

    • If you leave this connector unconnected, SC530-10 (Copy Tray Cooling Fan Lock) occurs.

  30. Turn the machine main power switch ON.
  31. Set SP1-907-001 (Exit Tray Full Detection) to “1: ON”.

    • The default setting of this SP is “0: OFF”. It must be set to “1: ON” in order for tray full detection to work.

  32. Attach the decal [A] to the left side of the main machine.

      • Align the lower side of the decal with the marker [A] on the main machine.

  33. Turn the power switch [A] of the cooling fan ON.


  • Always keep the power switch of the cooling fan ON. This is because the fan is installed to prevent paper from sticking together and jamming during duplex printing due to undried toner. (The fan stops when the print/copy job is complete.)
  • If the sound of the fan is unacceptable to the customer, or the air from the fan pushes thin paper off the exit tray, advise the customer to power off the fan as necessary.
  • If jams still occur while the fan is ON, tilt the fan 90 degrees as described in Troubleshooting for Blocking on the Paper Output Tray.
