TROUBLESHOOTING AND ROUTINE MAINTENANCE 11 - 12
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 4-4.)
Transferring a Fax Call to the
MFC. If you answered at the MFC, press Black Start and hang up
immediately. If you answered on an extension phone, press your F ax
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, Ring Master, Voice Mail,
an alarm system or any other custom feature on a sing le phone line with
your MFC, 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 s hould
help overcome this problem. This condition is related to the telephone
system industry and is common to all de vices that send and receive data
on a single, shared line with custom features. If avoiding a sligh t
interruption is crucial to your business, we recommend a separate
phone line with no custom features.
