Handling Incoming Calls

MFC ‘Hears’ Voice as CNG 
Tone.

If your MFC is set to Easy Receive ON, it is more sensitive to sounds. 
Your MFC 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 

Easy Receive

 on page 5-4.)

Sending a Fax Call to the 
MFC.

If you answered at the MFC, press 

Start

 and hang up immediately. If 

you answered on an external or extension phone, press your Fax 
Receive Code (default setting is (

51). When your MFC answers, 

hang up.

Custom features on a single 
line.

If you have Call Waiting, Call Waiting/Caller ID, RingMaster, Voice Mail, 
an answering machine, an alarm system or other custom feature on a 
single phone line with your MFC, it may create a problem sending or 
receiving fax data.

For Example:

 Your Brother MFC handles the Caller ID subscriber 

services. However, if you subscribe to Call Waiting or some other 
custom service and its signal comes through the line while your MFC is 
sending or receiving a fax, 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.

Menu Setting Difficulties

The MFC beeps when you try 
to access the Setup Receive 
and Setup Send menus.

Make sure that MFC is in Fax mode. If the Fax 

 key is not 

illuminated, press it to turn on Fax mode. Setup Receive setting 
(

) are available only 

when the MFC is in Fax mode.

Copy Quality Difficulties

Vertical streaks appear in 
copies.

Sometimes you may see vertical streaks on your copies. Either the 
scanner or the primary corona wire for printing is dirty. Clean them both.
