If You Are Having Difficulty with Your MFC
If you think there is a problem with your MFC, make a copy first. If the
copy looks good, the problem is probably not your MFC. Check the chart
below and follow the troubleshooting tips.
DIFFICULTY SUGGESTIONS
Printing or Receiving Faxes
Condensed Print and Horizontal If your copy looks good, you probably had a bad connection, with
Streaks / Top and Bottom of static or interference on the phone line.
Sentences Are Cut Off If a copy looks worse, then call your Brother dealer for service.
Vertical streaks/black lines appear on Sometimes you may see vertical streaks/black lines on the faxes you
the fax you receive receive. Either your machine’s primary corona wire for printing may
be dirty, or the sending party’s fax scanner may be dirty. Clean your
primary corona wire, or ask the sender to make a copy to see if the
problem is with the sending machine. Try receiving from another fax
machine. If the problem continues, call Brother dealer for service.
Phone Line or Connections
MFC Does Not Answer When Called 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 There is probably temporary noise or static on the line. Try sending the
“Result:NG”again. fax 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 in this chapter).
Handling Incoming Calls
Transferring a Fax Call to the MFC If you answered at an extension phone, press your Remote Activation.
Code (default setting is 51). When your MFC answers, hang up.
Custom Features on a Single Line If you have Voice Mail, an answering machine, alarm system or any
other on a single phone line with your MFC, it may create a problem
sending or receiving fax data. 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 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.
