TX Lock (MFC-7420 only)
TX Lock lets you prevent unauthorized

Polling jobs. However, any pre-scheduled
Delayed Faxes will be sent even if you turn on

are available:
■ Receiving faxes
■ Fax Forwarding
(if Fax Forwarding was already on)
■ Remote Retrieval
(if Fax Storage was already on)
■ PC Fax Receive
(if PC Fax Receive was already on)
While TX Lock is on, the following operations
are NOT available:
■ Sending faxes
■ Copying
■ PC printing
■ PC scanning

Note
■ If you have already set the password, you
