How can I prevent public access to certain features on my Brother machine?

Secure Function Lock is a feature that enables you to restrict public access to these functions of your Brother machine:

 

  • Fax Tx (Fax Transmission)
  • Fax Rx (Fax Reception)
  • Copy
  • Scan
  • PC Printing

Secure Function Lock also prevents users from changing the default machine settings by limiting access to these settings. You must disable at least one function if you want to turn Secure Function Lock on.
 

You can enable access to restricted operations by creating a restricted user profile. Restricted users must choose their user name from a list and enter a password to use the Brother machine.
 

  • Make a careful note of your password. If you forget it, please contact Brother Customer Service from "Contact Us".
     
  • You can set up to 10 individual restricted users and one general Public user.
     
  • When you set up a Public user, you can restrict one or more of the Brother machine's functions to all users who do not have a password.
     
  • Only administrators can set limitations and make changes to user profiles.
     
  • When PC Printing is disabled, your PC print jobs are lost without notification.
     
  • When Secure Function Lock is on, you can only adjust the following fax settings: Contrast, Polled Transmission, and Coverpage Setup.
     
  • If Fax Transmission is disabled, you cannot use any of the Brother machine's fax functions.
     
  • Polling Receive is enabled only when both Fax Transmission and Fax Reception are enabled.
