1. Remove the right cover [A]. (Right Cover)
  2. Remove the controller box cover [A].
  3. Remove the screws of the bracket [A] and the FCU board.
  4. Disconnect the speaker connector and remove the FCU board [A] with the bracket.
  5. Change the orientation of the battery jumper switch [A] on the removed FCU board [B], and then attach the battery jumper switch [C]. The battery jumper switch [C] comes with the new FCU board.


  6. Change the orientation of the battery jumper switch [A] on the new FCU board [B].

    • If the battery jumper switch is not in the correct position, SC820 will occur.

  7. Remove the HDD. (HDD)

    • It is not necessary to disconnect the HDD cable.

  8. Insert one end of the supplied flat cable [A] into the CN603 connector [B] on the new FCU board.

    • Make sure that the blue tape of the flat cable faces outward.

  9. Insert the new FCU board [A] into the machine and connect the speaker connector [B] to the new FCU board.
  10. Mount the old FCU board with bracket [A] to the controller box temporarily.

  11. Insert the other end of the flat cable [A] into the CN603 connector on the old FCU board [B].

    • To prevent a short circuit, make sure the old FCU board does not come into contact with anything metallic.
    • Make sure that the blue tape of the flat cable faces outward.

  12. Turn the main power ON.
    The SRAM data transfer begins. Transfer is complete when a beep sounds.

    • The volume of the beeping sound is set to the same level as the speaker volume.
    • If the speaker volume is set to off, the volume of the beeping sound is set to its initial factory-set level.
    • If the machine does not beep, turn the main power OFF and then ON, and attempt data transfer again. Try several times if necessary.
    • Be sure to check the transfer result after executing data transfer. If the transfer has failed, you need to specify settings manually in the SP mode.

  13. When "Ready" is displayed on the control panel, turn the power OFF, and remove the AC power plug from the receptacle.
  14. Disconnect the flat cable from both FCU boards.

  17. Remove the bracket [B] from the old FCU board [A] and attach the bracket to the new FCU board.
  18. Mount the new FCU board in the machine and connect the speaker connector to the new FCU board.
  19. Reattach the controller box cover.
  20. Reattach the cover.
  21. Turn the main power ON.
  22. Enter the SP mode.
  23. Print the system parameter list from SP6-101 in the Fax SP menu, and then check the list to see whether the SRAM data has been transferred correctly.

  24. Set the correct date and time from the [User Tools].

    • User Tools > Machine Features > System Settings > Timer Setting > Set Date/Time
