You can set up your machine with multiple 

levels of security using Setting Lock and TX 

Lock (MFC-7340, MFC-7345N and MFC-

7440N only) or Secure Function Lock 

(MFC-7840W only). You will not be able to 

continue to schedule Delayed Faxes or 

Polling jobs. However, any prescheduled 

Delayed Faxes will be sent even if you turn on 

TX Lock or Secure Function Lock, so they will 

not be lost.
