   TROUBLESHOOTING AND ROUTINE MAINTENANCE

Handling Incoming Calls

The machine ‘Hears’ Voice as 
CNG Tone.

If your machine is set to Easy Receive ON, it is more sensitive to 
sounds. Your machine may mistakenly interpret certain voices or music 
on the line as a calling fax machine and respond with fax receiving 
tones. Deactivate the fax by pressing 

Stop/Exit

. Try avoiding this 

problem by turning Easy Receive to Off. (See  on page 4-5.)

Transferring a Fax Call to the 
machine.

If you answered at the machine, press 

Black Start

 and hang up 

immediately. If you answered on an extension phone, press your Fax 
Receive Code (default setting is (

51). When your machine answers, 

hang up.

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 machine, it may create a problem sending or receiving faxes.
For example: If you are sending or receiving a fax message while a 
custom feature signal comes through on the line, 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 data 
on a single, shared line with custom features. If avoiding a slight 
interruption is crucial to your business, we recommend a separate 
phone line with no custom features.
