The administrator can confirm whether the structure change is necessary or not by checking the
firmware version displayed on the control panel screen. If the firmware structure change is
unnecessary, contact your service representative.
When Change Firmware Structure is set to [Prohibit], administrator authentication must be enabled.
After [Prohibit] is specified, turn off administrator authentication once, and the next time administrator
authentication is specified, the setting will return to the default, [Do not Prohibit].
If you select [Do not Prohibit], firmware structure change detection is disabled.
