Ricoh AFICIO MP C305SP Manual page 606

Specify whether to allow firmware updates on the machine. Firmware update means having the
service representative update the firmware or updating the firmware via the network.
If you select [Prohibit], firmware on the machine cannot be updated.
If you select [Do not Prohibit], there are no restrictions on firmware updates.
Default: [Do not Prohibit]
Change Firmware Structure
This can be specified by the machine administrator.
Specify whether to prevent changes in the machine's firmware structure. The Change Firmware
Structure function detects when the SD card is inserted, removed or replaced.
If you select [Prohibit], the machine 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 machine finishes startup with the updated firmware.
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, disable administrator authentication. When administrator authentication
is enabled again, you can return the setting to [Do not Prohibit].
If you select [Do not Prohibit], firmware structure change detection is disabled.
Default: [Do not Prohibit]
Password Policy
This can be specified by the user administrator.
This setting lets you specify [Complexity Setting] and [Minimum Character No.] for the password.
By making this setting, you can limit the available passwords to only those that meet the conditions
specified in "Complexity Setting" and "Minimum Character No.".
If you select [Level 1], specify the password using a combination of two types of characters
selected from upper-case letters, lower-case letters, decimal numbers, and symbols such as #.
If you select [Level 2], specify the password using a combination of three types of characters
selected from upper-case letters, lower-case letters, decimal numbers, and symbols such as #.
Default: [Off], Minimum required number of characters not specified
Settings by SNMPv1, v2
This can be specified by the network administrator.
When the machine is accessed using the SNMPv1, v2 protocol, authentication cannot be
performed, allowing machine administrator settings such as the paper setting to be changed. If you
select [Prohibit], the setting can be viewed but not specified with SNMPv1, v2.
