Comparison of the PM parts replacement procedures

PM parts replacement procedure for this model is different from many older models. If the PM counter is reset in “PM parts display”, a flag is set (SP3-701-XXX) and initial process SPs are run automatically for the replaced part. See below for details. If the PM counter is reset in SP7-622-XXX, the procedure is the same as many older models.

  • If the counter for the Lubricant Bar is reset in SP7-622-XX, make sure to set SP3-701-XXX to "1". Otherwise, the lubricant end detection (SP3-810-XXX) will not be reset and the banner message indicating near-end will remain on the operation panel.

PM part replacement procedure

  1. Turn OFF the power on the operation panel button, and unplug the AC power cord.

  2. Turn OFF the main power switch located inside the door.

  3. Replace the PM parts.

  4. Plug in the AC power cord and turn on the main power switch with either the bypass tray door [A] or vertical transport door [B] opened.

    • Make sure to open either the bypass tray or vertical transport door before turning on the main power. Otherwise, problems could occur as a result of unnecessary initialization processes.

  5. Enter the SP mode and push the PM parts counter reset button in the PM Parts display. (PM Counter Display)

    • Pressing the reset button in the PM Counter Display does not reset the PM counter. The PM counter is reset after closing the door in step 6.

  6. Close the bypass tray door (or the vertical transport door). The machine will reset the PM counters automatically followed by an initialization process.

  7. Execute initialization in the SP mode, if required. (For details about which SPs to execute, see the replacement and adjustment procedures for each part.)

  8. Enter SP5-990-004 and check the counter values in the SMC logging data.
    Make sure that the PM counters for the replaced units are "0" in the PM parts display.
    If a PM counter for a unit that had been replaced does not display “0,” reset that counter in the procedure described above.

  9. Exit the SP mode.

  • The machine will automatically stop when the PM counters for the fusing cleaning web and drum lubricant bar reach their yield.
  • Counter clearance is not required when replacing the developer, because this counter is cleared by SP3-024 (Developer Fill: Execute).
  • Counter clearance triggers the initialization of the parts described in this section. When initialization is required for these parts, open the front door and clear the counter.
