• SC195 (Machine serial number error) will be displayed if you forget to attach 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.
  • Installing a new NVRAM initializes SPs and issues an SC. Reset the SC with the procedure below.

  1. Make sure that you have the SMC report (factory settings). This report comes with the machine.
  2. Output the SMC log using one of the following methods:
    To print SMC log data, execute SP5-990-001.
    To save SMC log data to an SD card, execute SP5-992-001 (SMC List Card Save Function).
  3. Turn off the main power switch.
  4. Insert a blank SD card in the 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 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. Do the following steps if the machine has the fax unit. If not, skip this step:
    1. Print the Box List with the User Tools/Counter.
      • [User Tools/Counter] - [Facsimile Features] - [General Settings] - [Box Setting: Print List]
    2. Print the Special Sender List by pressing these buttons in the following order.
      • [User Tools/Counter] - [Facsimile Features] - [Reception Settings] - [Program Special Sender: Print List]
    3. Write down the following fax settings.
      • [Receiver] in [User Tools/Counter] - [Facsimile Features] - [Reception Settings] - [Reception File Settings] - [Forwarding].
      • [Notify Destination] in [User Tools/Counter] - [Facsimile Features] - [Reception Settings] - [Reception File Settings] - [Store].
      • [Specify User] in [User Tools/Counter] - [Facsimile Features] - [Reception Settings] - [Stored Reception File User Setting].
      • [Notify Destination] in [User Tools/Counter] - [Facsimile Features] - [Reception Settings] - [Folder Transfer Result Report].
      • Specified folder in [User Tools/Counter] - [Facsimile Features] - [Send Settings] - [Backup File TX Setting].
      • [Receiver] in [User Tools/Counter] - [Facsimile Features] - [Reception Settings] - [Reception File Settings] - [Output Mode Switch Timer].
      • [Store: Notify Destination] in [User Tools/Counter] - [Facsimile Features] - [Reception Settings] - [Output Mode Switch Timer].
      • All the destination information shown on the display.

      • In the fax settings, address book data is stored with entry IDs, which the system internally assigns to each data. The entry IDs may be changed due to re-assigning in backup/restore operations.

    4. Make sure that there is no transmission standby file. If any standby file exists, ask the customer to delete it or complete the transmission.
  8. Turn the main power OFF and unplug the power supply cord.
  9. Push the main power switch ON again to discharge the residual charge.
  10. Replace the NV-RAM with a new one.
  11. Turn the power ON.

    • 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.

    1. Change the SP settings for the operation panel.
      • 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”.
  12. Cycle the main power OFF/ON with the SD card where the NV-RAM data has been uploaded in SD slot 2.

    • SC992 appears at start-up, but this is normal behavior. This is because information written to the NV-RAM and on the hard disk do not match due to replacement of the NV-RAM. Go to Step 13.

  13. 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.

  14. Turn the main power OFF and remove the SD card from SD slot 2.
  15. Turn the main power ON.
  16. Restore the original settings of the following SPs, referring to the SMC data obtained in step 2.

    • SP5-825-001 does not download the following SP data to the new NV-RAM. So you must set them manually.

    a. SP5-985-001(Device Setting: On Board NIC)
    b. SP5-985-002(Device Setting: On Board USB)
  17. If the security functions (HDD Encryption and HDD Data Overwrite Security) were applied, set the functions again.
  18. 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 have obtained the backup of the customer’s address book data, delete the backup immediately after the NV-RAM replacement to avoid accidentally taking out the customer’s data.

  19. Output the SMC log using one of the following methods:
    To print SMC log data, execute SP5-990-001.
    To save SMC log data to an SD card, execute SP5-992-001 (SMC List Card Save Function).

    • Check that the counters are reset.

  20. Make sure that the list output in step 7-1 through step 7-3 matches the destination information in step 7-4. If not, set it to the setting before replacement.
  21. Execute the process control (SP3-011-001).

    • Try all the items below if NVRAM upload (SP5-824-001) or download (SP5-825-001) cannot be done.
    • Check the SP values that changed on the SMC you printed out in step 2. Adjust the values manually. Make sure that the values of SP5-045-001 and SP5-302-002 are the same as before replacing.
    • Replace all PM parts because all PM counters will be reset.

    • If a message tells you need an SD card to restore displays after the NVRAM replacement, create a “SD card for restoration” and restore with the SD card. Refer to “Encryption Key Restoration”
