Notes:
• Written firmware varies depending on the kinds of the boards provided as service parts. For
updating, only the minimum firmware is installed on the system control PC board, logic PC
board, and scanning section control PC board. No firmware is installed on the FAX board.
The latest version of the firmware at the time of delivery is written on the RADF control PC
board and finisher control PC board.
When any of above boards is replaced with a new one in the field, check the other firmware
version used and then update with a corresponding suitable version.
• "Can't fetch Ver." is displayed in the Installed Version field when the version of the installed
firmware cannot be acquired properly. If a normal power on is not performed after the
firmware is updated and the [ON/OFF] button is pressed while simultaneously holding down
the [4] and [9] buttons, "Can't fetch Ver." may be displayed on the control panel for some
firmwares. A normal power on must be performed.
