MFC Does Not Answer
When Called Make sure the MFC is not in MANUAL mode. Check for dial
tone. If possible, call your MFC to hear it answer. If there is
still no answer, check the telephone line cord connection. If
there is no ringing when you call your MFC, call your
Telephone Company to check the line.
Sending Faxes
Poor Transmitting Quality Try changing your resolution to FINE or S.FINE. Make a
copy to verify your MFC’s scanner operation.
Transmission Verification
Report says “Result:NG” There is probably temporary noise or static on the line. Try
sending the fax again. If the problem continues, call the
Telephone Company to check your phone line.
Vertical Black Lines When
Sending If the copy you made shows the same problem, your scanner
is dirty. (See Cleaning the Scanner, page 21-16.)
Handling Incoming Calls
Transferring a Fax Call to the
MFC If you answered at an extension phone, press your Fax
Receive 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,
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 machine 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 machine 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.
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. (See pages 21-16 and 21-18.)
