    • Setting.ini (Parameter setting)
    • xxx.brn (Controller Firmware)
  2. Make a folder on a local drive of your computer and save the files there.
  3. Turn the machine on.
  4. Connect the computer and the machine through a network or directly by USB.
  5. Double-click the "FWUpdateTool.exe" file to execute the updating program.
    A dialog box with cautionary statements appears.
  6. Read the cautionary statements carefully, and then click "OK".

     
    The firmware update tool opens.

  7. For a USB connection, click "Firmware Update (USB)" [A].
    For a network connection, enter the machine's IP address in "Machine IP address" [B], and then click "Firmware Update (LAN)" [C].


    The firmware update starts.

    • When the firmware update starts:
      For Printer models: The alert LED starts to light up.
    • For MF models: The alert LED starts to light up and machine makes a beep sound.

  8. Check the machine’s control panel for messages and the update’s current percentage of completion.

    • Do not turn the main power off from this point until the update procedure is completed.

  9. Wait until the update completion message appears on the machine’s control panel.

  • Do not turn off the machine until the update completion message appears on the machine’s control panel. Otherwise, the controller board will be damaged.
  • If the update completion message does not appear, the download failed. Try again. You can also switch from an Ethernet connection to a USB connection and see if that works. If you still cannot download the firmware, it may be necessary to change the EGB and/or the controller board.
  • If power failed during the download, try again. If you still cannot download the firmware, it may be necessary to change the EGB and/or the controller board.
