• Referring to the previous procedure, be sure that there are no mistakes in the mounting position and orientation of the NVRAM.

  • If you mounted the NVRAM in the wrong direction, each component needs to be replaced because a short circuit was caused in the controller board and the NVRAM.

  1. Make sure you have the SMC report (factory settings). This report comes with the machine.
  2. Output all the SMC data using SP5-990-001 (SP Print Mode: All (Data List)).
  3. Turn off the main power switch.
  4. Insert a blank SD card in SD slot 2, and then turn on the main power switch.
  5. Use SP5-824-001 to upload the NVRAM data from the controller board.
  6. Make sure the customer has a backup of their address book data. If not, obtain the backup by referring to the following procedure.
    1. Insert an SD card into SD slot 2, and then turn the main power ON.
    2. Save the address book data in the SD card using SP5-846-051.

    • The address data stored in the machine will be discarded later during this procedure. So be sure to obtain a backup of the customer’s address book data.
    • Note that the counters for the user will be reset when doing the backup/restore of the address book data.
    • If they have a backup of the address book data, use their own backup data for restoring. This is because there is a risk that the data cannot be backed up properly depending on the NVRAM condition.

  7. Turn the main power OFF and unplug the power supply cord.
  8. Push the main power switch ON again to discharge the residual charge.
  9. Remove the SD card from SD slot 2.
  10. Replace the NV-RAM with a brand-new one.

  11. Turn the power ON while the SD card is removed from SD slot 2.

    • SC673 appears at start-up, but this is normal behavior. This is because the controller and the smart operation panel cannot communicate with each other due to changing the SP settings for the operation panel.

  12. Change the SP settings for the operation panel.
    If you switch the screen to enter the SP mode, SC995-02 is displayed. However, continue the following steps.

    • SP5-748-101: (OpePanel Setting: Op Type Action Setting): Change bit 0 from 0 to 1.

    • SP5-748-201: (OpePanel Setting: Cheetah Panel Connect Setting): Change the value from 0 to 1.

  13. Cycle the power OFF/ON.

    • The model information is written on the NVRAM (Novita), so SC995-02 does not occur.
    • Program/Change Administrator will be displayed in Japanese, but this is normal.

  14. Turn OFF the main power, take the SD card to which the NV-RAM data has been uploaded, and insert it into SD slot 2.

  15. Turn ON the main power.

  16. Download the NV-RAM data stored in the SD card to the brand-new NV-RAM using SP5-825-001 (NV-RAM Data Download).

    • The download will take a couple of minutes.

  17. Turn the power OFF and remove the SD card from slot 2.

  18. Turn the power ON.
    The screen "Program/Change Administrator" will be displayed in the language that is the same language as the time when the data was uploaded to the SD card in step 5.

  19. If the security functions (e.g. Stored file encryption/ Auto Erase Memory Setting) were applied, set the functions again.

  20. Ask the customer to restore their address book. Or restore the address book data using SP5-846-052 (UCS Setting: Restore All Addr Book), and ask the customer to ensure the address book data has been restored properly.

    • If you obtained the backup of the customer’s address book data in step 3, delete the backup immediately after the NV-RAM replacement to avoid accidentally taking out the customer’s data.

  21. Output all the SMC data with SP5-990-001 and make sure all the SP/UP settings except for counter information are properly restored, by checking the SMC data obtained in step 2.

    • The counters will be reset.

  22. If the setting is different from the original setting after the replacement of the NVRAM, then set it again to the original setting.

  23. Execute the process control (SP3-011-001).

  24. Cycle the power OFF/ON.

    • If you cannot execute SP5-824-001 or SP5-825-001 for some reason, try all the following things.
      - Check the changed SP value on the SMC which was output in step 2 and set it manually. Especially, ensure that the values of the following SPs are same as the setting before the replacement.
      - a. SP5-104-001 (A3/DLT Double Count)
      - b. SP5-104-002 (Bypass Paper Size Undetection)
      - c. SP5-302-002 (Set Time: Time Difference)
    • Because the PM counters have been reset during NV-RAM replacement, it is necessary to replace all the PM parts for proper PM management.

    • If a message tells you need a SD card to restore displays after the NV-RAM replacement, create a “SD card for restoration” and restore with the SD card.
