TROUBLESHOOTING AND ROUTINE MAINTENANCE 10 - 11
Handling Incoming Calls
The machine ‘Hears’ Voice as
CNG Tone.
If your machine is set to Fax Detect 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 Fax Detect to Off. (See Fax Detect (MFC-3240C only) on page
4-4 and Fax Detect (FAX-1840C only) on page 4-5.)
Transferring a Fax Call to the
machine.
If you answered at the machine, press Mono 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 machine
answers, hang up.
Custom features on a single
line.
If you have Call Waiting, Call Waiting/Caller ID, 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.
