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

Custom features on a single line.

If you have Call Waiting, Call Waiting/Caller ID, Caller ID, Voice Mail, an

 

 

answering machine, 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 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 line with no custom features is recommended.
