Secure Function Lock
(MFC-7840N only)

Secure Function Lock lets you restrict Public access to certain machine functions (Fax Tx, Fax Rx, Copy, Scan and Print1).
This feature also prevents users from changing the Default settings of the machine by limiting access to the Menu settings.
Disabling at least one function is required to turn on Secure Function Lock for the Public user.
Before using the security features you must first enter an administrator password.
Access to restricted operations can be enabled by creating a restricted user. Restricted users must enter a user password to use the machine.
Make a careful note of your password. If you forget it, please call your Brother dealer for service.
