Restricting the Machine's Functions

Some of the functions of the machine may rarely be used or provide opportunities for misuse. For security purposes,
the machine can be set to limit its capabilities by partially or completely disabling these functions.
Restricting Access to Address Book and Sending Functions
You can specify the PIN in the Address Book to disable a general user from modifying data or limit destinations
that can be specified for fax sending. You can also disable a user from collectively sending a fax to multiple
destinations (Sequential Broadcast). Restricting Access to Address Book and Sending Functions(P. 402)
Restricting Printing from a Computer
You can limit "printing from computer" only to secure documents so that no print jobs can be executed unless
the PIN is entered on the machine side. Restricting Printing from a Computer(P. 409)
Restricting USB Functions
The USB connection allows an easy connection with peripheral devices, but it may cause a security risk such as
an information leakage. You can restrict a USB connection with a computer or saving to a USB memory device.
