My Brother machine is dialing the wrong number or is not dialing the number I entered or I receive a busy signal or recording when trying to send faxes.

If your Brother machine consistently dials numbers other than the ones you have entered or you receive a busy signal or recording when trying to send faxes, you may have programmed a Dial Prefix on the machine. The Dial Prefix is a feature that automatically dials a user-defined number before every fax you send.



For example, if your telephone system requires you to dial 9 to access an outside line, then you can program the Dial Prefix feature to automatically dial 9 every time you send a fax.



To change or delete the prefix number programmed in your Brother machine follow these steps:
