After Replacement of a Defective NVRAM

  1. You will need the factory settings sheet provided with the machine.
  2. Turn the power on, enter the SP mode, and then do the factory settings.
  3. Re-install security settings as required.
  4. Go into the SP mode and open SP5104-001.
    • This SP may automatically reset to "0" after NVRAM replacement.
    • This SP code should be reset to "1" (factory default), unless the operator needs it set to "0".

NVRAM Upload and Download

  1. Make sure that you have the SMC report (factory settings). This report comes with the machine.
  2. Output the SMC data (“ALL”) using SP5-990-001.
  3. Turn off the main switch.
  4. Insert a blank SD card into Slot 2, and then turn on the machine.
  5. Upload the NVRAM data to the blank SD card using SP5-824-001 (NVRAM Data Upload).
  6. Enter the SP mode, open SP5985-001 (Enable onboard NIC) and SP5985-002 (Enable onboard USB), and make a note of their settings. (It is necessary to enter these settings manually after the NVRAMs have been replaced.
  7. Turn off the main power switch, and then unplug the power cord.
  8. Remove the SD card from Slot 2.
  9. Replace the NVRAM on the controller board with a new one, plug in the power cord, and then turn on the main power switch.
  10. Do SP5846-051 to copy all address data to the SD card.
  11. Turn the machine off, and then unplug it.
  12. Remove the SD card with the address book data from Slot 2.

  13. Swap the old NVRAMs on the controller board with new ones.

    The two NVRAMS on the controller board are labeled 2M-1 and 2M-2.

    These NVRAMs are a set. When replacing the controller board, remove both NVRAMs, 2M-1 and 2M-2, and then attach them to the new board at the same locations. If this is not done correctly, the machine will issue SC195-00.

    When you position the NVRAMS over the sockets, make sure that the circular notch is pointing in the direction embossed on the board as shown below.

    NVRAM 2M-1 is inserted into socket FRAM-1, and 2M-2 is inserted into the socket FRAM-2. Make sure that the circular notches on the NVRAMs point in the direction of arrows embossed on the board.

    If the NVRAMs are installed incorrectly, this could cause both the board and the NVRAMs to short out and permanently damage the board and NVRAMs

  14. .After the board is replaced, check which ESA applications have been installed, and then follow the installation procedures to re-install each application.
  15. Make sure that there is no SD card in Slot 2, and then plug in the power cord and turn the machine on.
  16. If the machine returns SC995-02, cycle the machine off and try again.
  17. Insert the SD card with the copied NVRAM data in Slot 2.
  18. Do SP5825-001 to download the data from the SD card. This requires two or three minutes to complete.
  19. When you see the “Finished!” message, cycle the machine off/on, and then touch [Exit]. Do not turn the machine off.

  20. If SC870-11 (Address Book Data Error) appears, ignore it.

    After doing a setting, if the machine prompts you to cycle the machine off/on, ignore this message and continue until all the settings are done.

  21. Enter the SP mode and manually enter the settings for the SP codes that you recorded above SP5985-001 (Enable onboard NIC) and SP5985-002 (Enable onboard USB).
  22. Turn the machine off and remove the SD card from Slot 2.
  23. Turn the machine on.
  24. Insert the SD card with the address book data into Slot 2.

  25. Do SP5846-052 to restore the address book data.

    The execution will fail if the settings at Step 16 for SP5985-001 or SP5985-002 were not done correctly.

    If this execution succeeds, the machine will prompt you to cycle the machine off/on.

  26. Switch the machine off, and then remove the SD card from Slot 2.
  27. Turn the machine on.
  28. Enter the SP mode and print another SMC report with SP5990-001, compare it with the original SMC report that you printed earlier, and then correct any settings.
  29. Reset the NVRAM counter (Total counter: 1000, other counters to zero).
  30. Execute process control.
  31. If you see the message “SD Card for Restoration is Required”, the data encryption key must be re-installed.
