I have difficulty 
transferring a fax call to 
the MFC.

If you answered at an extension phone, press your 
MFC’s Remote Activation Code (default setting is 

51). When your MFC answers, hang up.

I have difficulty with 
custom features on a 
single line. 

If you have Call Waiting, Call Waiting/Caller ID, 
Ring Master, Voice Mail, an alarm system or any 
other custom feature on a single phone line with 
your MFC, it may create a problem sending or 
receiving fax data.
For example: 
If you are sending or receiving a fax message while 
a custom feature signal comes through the line, the 
signal can temporarily interrupt or disrupt the fax 
data. 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.
