If you select [Prohibit], the printer stops during startup when a firmware structure change is detected
and a message requesting administrator login is displayed. After the machine administrator logs in,
the printer finishes startup with the updated firmware.
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.
Default : [Do not Prohibit]
