When you replace the FCU board, transfer the SRAM data from the old FCU board to the new FCU board. Do the following procedure to back up the SRAM data.

  • The following data can be transferred: TTI, RTI, CSI, Fax bit switch settings, RAM address settings, NCU parameter settings.

Check "LINE2" to see if the G3 unit is installed.

G3 Unit Installed

No G3 Unit Installed

  1. Remove the controller box cover [A].
  2. Remove the interface slot cover [A].
  3. Remove the rear cover [A].
  4. Remove the controller box cover [A].
    Red circle: remove
    Blue circle: loosen
  5. If the optional G3 interface unit is installed, remove the FFC from the FCU.
  6. Pull out the FCU [A] from the interface slot.
  7. Remove the slot cover [A].
  8. Change the orientation of the battery jumper switch [A] on the removed FCU board, and then attach the battery jumper switch [B] on the FCU board to switch to the Restore mode.
    The battery jumper switch [B] is supplied with the new FCU board.

  9. Switch the battery jumper switch [A] of the new fax unit to the "ON" position before installing.

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

  10. Replace the installed FCU board [A] with a new FCU board.
  11. Reinstall the new fax unit, and then the slot cover (x 2).
  12. Attach one end of the flat cable [A] to CN603 of the new fax unit.
    • When inserting the cable, make sure that it is not slanted.
    • Connect the FFC in the direction as photo below.
  13. Attach the bracket [A] (provided as a service part) to the center frame of the controller box.

  14. Attach the removed FCU board [A] to the bracket.
    Then attach the other end of the flat cable to the connector [B] of CN603 on the removed FCU board.

    • When inserting the cable, make sure that it is not slanted.
    • Make sure that the blue tape of the flat cable faces outward.

    • Keep the removed FCU board away from the metal frames. Otherwise, the removed FCU board may have a short circuit.

  15. Turn ON the main power.
    SRAM data transmission starts. When the transmission is completed, you will hear a beeper sound.

    • The beeper sound is at the same volume as the speaker sound.
    • The beeper sounds even if the speaker sound is turned off.
    • If the beeper does not sound, repeat main power OFF/ON until the beeper sounds, and then perform the transmission procedure. If the data cannot be transmitted, repeat transmission 2 or 3 times.

  16. When “Ready” is displayed on the display panel, turn OFF the main power. Disconnect the flat cable from the removed FCU board.
  17. Remove the removed FCU board (x 1).
  18. Remove the bracket from the center frame of the controller box (x 1).
  19. Disconnect the flat cable from the new FCU board.
  20. Re-assemble the machine.
  21. Turn ON the main power. Execute SP6-101 to print the system parameter list.
  22. Check the system parameter list to make sure that the data is transferred correctly.
  23. Set the correct date and time with the User Tools: User Tools > System Settings > Timer Setting > Set Date/Time.
