1. Make sure that you have the SMC report (factory settings). This report comes with the machine.

  2. Print out the SMC data (“ALL”) in SP5-990-001.

  3. Turn OFF the main power switch.

  4. Insert a blank SD card into slot #2, and then turn on the main power switch.

  5. Upload the Address Book Data to the blank SD card in SP5-846-051 (UCS Setting / Back Up All Addr Book).

    • Procedure for MP C6503/C8003 only
      If the Fax Option is installed on the machine, do the following:
      • Print out the "Box Setting List". (User Tools -> Facsimile Features -> General Settings -> Box Setting: Print List)
      • Print out the "Program Special Sender List". (User Tools -> Facsimile Features -> Reception Settings -> Program Special Sender: Print List)
      • Take note of the settings in "User Tools -> Facsimile Features -> Reception Settings".
      • Take note of the settings in "User Tools -> Facsimile Features -> Send Settings".

  6. Turn OFF the main power switch, and then unplug the AC power cord.

  7. Remove the SD card containing the Address Book Data from slot #2.
  8. Insert another blank SD card into slot #2, plug in the AC power cord, and then turn on the main power switch.

  9. Upload the NVRAM data to the blank SD card in SP5-824-001 (NVRAM Data Upload).

    • Make sure to note the following SP settings as they will not be automatically uploaded to the SD card. These settings will be input manually in Step 16.

      • SP5-193-001 (External Controller Info. Setting)
        0: No external controller, 1: EFI controller

      • SP5-895-001 (Application invalidation / Printer )
        0: Valid, 1: Invalid

      • SP5-895-002 (Application invalidation / Scanner )
        0: Valid, 1: Invalid

      • SP5-985-001 (Device Setting / On Board NIC )
        0: Invalid, 1: Valid

      • SP5-985-002 (Device Setting / On Board USB )
        0: Invalid, 1: Valid

  10. Turn OFF the main power switch, and then unplug the AC power cord.

  11. Remove the SD card containing the NVRAM data from slot #2.

  12. Replace the two NVRAMs on the Controller Board with the new ones.

    • There are two NVRAMs on the controller board as mentioned in When installing the New Controller Board. Make sure to replace the two NVRAMs as a set.
    • NVRAMs [A] and [B] installed on the Controller Board at the factory are labeled "2M-1" and "2M-2" respectively. NVRAMs procured as service parts are labeled "FRAM1/D261E" and "FRAM2/D261E".

    • Install NVRAM "FRAM1/D261E" in the socket printed "FRAM-1" [C] on the controller board. Install so that the indentation [E] on the NVRAM faces toward the direction indicated with the arrow [G] printed on the controller board.

    • Install NVRAM "FRAM2/D261E" in the socket printed "FRAM-2" [D] on the controller board. Install so that the indentation [F] on the NVRAM faces toward the direction indicated with the arrow [H] printed on the controller board.

    • Work carefully to avoid mistakes when installing the NVRAM. Incorrect installation will damage both the NVRAM and controller board.

  13. Plug in the AC power cord, and then turn ON the main power switch.

    • DO NOT insert the SD card containing the NVRAM data that you removed in Step 7 before turning on the main switch.
    • SC995-02 (Defective NVRAM) will appear when powering on the main power switch, but ignore this SC. DO NOT turn off the main power switch. Continue with this procedure.

  14. Re-insert the SD card containing the NVRAM data that you removed in Step 7 back into slot #2.

  15. Download the old NVRAM data from the SD card onto the new NVRAM in SP5-825-001 (NVRAM Data Download).

    • This will take about 2 or 3 minutes.

    • After the download completes, "Completed. You have to reboot." will appear, but ignore this message and press the “Exit” button. DO NOT reboot at this moment.
    • SC870-11 (Address Book Data Error) will appear in the banner, but DO NOT turn off the main power switch. Continue with this procedure.

  16. Input the following SP settings according to the notes took in Step 5.

    • SP5-193-001 (External Controller Info. Setting)

    • SP5-895-001 (Application invalidation / Printer)

    • SP5-895-002 (Application invalidation / Scanner)

    • SP5-985-001 (Device Setting / On Board NIC)

    • SP5-985-002 (Device Setting / On Board USB)

    • "Completed. You have to reboot." will appear after inputting each of the above SP settings, but ignore this message and press the “Exit” button. DO NOT reboot at this moment.

  17. Turn OFF the main power switch. This will take about 3 minutes. Wait until the machine power is turned off completely, and then remove the SD card from slot #2.

  18. Turn ON the main power switch.

  19. Insert the SD card containing the Address Book Data removed in Step 11 into slot #2.

  20. Execute SP5-846-052 (UCS Setting / Restore All Addr Book) to download the Address Book Data on to the new NVRAM.

    • SP5-846-052 will fail, if the settings in SP5-193-001, SP5-985-001 and SP5-985-002 input in Step 16 are incorrect.
    • "Completed. You have to reboot." will appear if SP5-846-052 results in success.

  21. Turn OFF the main power switch and remove the SD card from slot #2.

  22. Turn ON the main power switch.

    • Procedure for MP C6503/C8003 only
      Make sure that the “Reception Settings” and “Send Settings” correspond with the notes took in Step 9. Correct the settings if they are wrong.

  23. Print out the SMC data (“ALL”) in SP5-990-001, and make sure that it matches the SMC data printed out in Step 2 (except for the total counter value).

    • The total counter value is reset to “0” when the NVRAM is replaced.

  24. Do the self-check Process Control.

  25. Do ACC for the copier application program.

  26. Do ACC for the printer application program.

    • If you cannot execute SP5-824-001 (NVRAM Data Upload) and SP5-825-001 (NVRAM Data Download) for some reason, try the following.
      • Restore the settings manually with all the data on the SMC report (factory default setting) provided with the machine.
      • Re-install the Data Overwrite Security function and HDD Encryption feature.

    • If the message “SD card for restoration is required.” appears after the NVRAM replacement, restore the encryption key.
