The administrator can confirm if the updated structure change is permissible or not by checking the
firmware version displayed on the control panel screen. If the firmware structure change is not
permissible, contact your service representative before logging in.
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.
Default: [Do not Prohibit]
