Do this procedure after installing a new ITB.

  1. Make sure that the machine is turned off.
  2. Open the front doors.
  3. With the ITB unit and ITB cleaning unit both installed, make sure that the levers of the ITB cleaning unit are up so that the lubricant blade and cleaning blade are separated from the belt.
  4. Remove the PTR. (PTR Unit Removal)

  5. Remove the drum cleaning unit. (Drum Cleaning Unit)

    • Normally the ITB and PTR rotate together because they are driven by the same motor. The PTR must be removed before switching on the belt lubrication mode to prevent the cleaning blade from hanging up and scouring the PTR during idle rotation.
    • Similarly, the drum cleaning unit must also be removed before switching on the belt lubrication mode to prevent the cleaning blades of the drum cleaning unit from hanging up and scouring the surface of the bare drum during idle rotation.
    • The drum cleaning unit and ITB cleaning unit both have lubricant bars, but toner also acts as a lubricant during normal operation. Due to the absence of toner in the belt lubrication mode, the lubricant alone is not enough to prevent the blades from hanging up on and scouring the drum, so the drum cleaning unit should also be removed.

  6. Re-attach the front edge cover.
  7. Turn the main machine on.
  8. Enter the SP mode, and then do SP2310-001 to enter belt lubrication mode.
  9. After touching [EXECUTE] close the left and right doors of the machine.
  10. Wait about 5 min. for the machine to lubricate the ITB.
  11. A message on the operation panel will tell you when the procedure is finished.
  12. Once again, open the left and right door of the machine.
  13. Turn the main machine off.
  14. Re-install the PTR unit.
  15. Re-install the drum cleaning unit.
  16. Turn the levers to close the gap between the lubricant blade and the cleaning blade.
  17. Turn the main machine on.
  18. Enter the SP mode, and then reset the PM counters for all the replaced parts.
  19. Leave the SP mode, and then close the front doors.
  20. Process control will start automatically.
  21. The machine will display “Ready” after process control executes successfully.
  22. Enter the SP mode, and then do SP3012-001 to confirm successful completion of the process control execution.
  23. If process controls fails, correct the problem by following the steps recommended for releasing the SC code.
  24. After correcting the problem, service control will not execute automatically, so you will need to execute process control manually with SP3011-002.
