Suggestions
If Fax Detect is set to On, your machine is more sensitive to sounds. It may
mistakenly interpret certain voices or music on the line as a fax machine calling
and respond with fax receiving tones. Deactivate the machine by pressing
Stop/Exit. Try avoiding this problem by turning Fax Detect to Off.
(See Fax Detect on page 39.)
If you answered on an extension or external telephone, press your Remote
Activation Code (the factory setting is l 5 1). If you answered on an external
telephone, press Start to receive the fax. When your machine answers, hang up.
If you have Call Waiting, Call Waiting/Caller ID, an alarm system or other custom
feature on a single telephone line with your machine, it may create a problem
sending or receiving faxes.
For example: If you subscribe to Call Waiting or some other custom service and
its signal comes through the line while your machine is sending or receiving a fax,
the signal can temporarily interrupt or disrupt the faxes. Brother's ECM (Error
Correction Mode) feature should help overcome this problem. This condition is
related to the telephone system industry and is common to all devices that send
and receive information on a single, shared line with custom features. If avoiding
a slight interruption is crucial to your business, a separate telephone line with no
custom features is recommended.
