Toshiba e-STUDIO477S Service Manual page 291

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,
scanning section control PC board, and 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.
