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
Streaks / Top and Bottom of
Sentences Are Cut Off
If your copy looks good, you probably had a bad connection, with static or
interference on the phone line. If the copy looks bad, call Brother Customer
Service at 1-800-284-4329 (USA), 1-800-853-6660 (from within Canada)
or 1-514-685-6464 (from within Montreal).
Poor Quality Print Make sure the Printer Driver matches the type of paper you are using (see
15-1). If you are using plain paper, try using recommended special paper
(see Chapter 3). Don’t handle the paper until the ink is dry. Adjust the
Vertical Alignment (see page 24-9).
Smudged stain on the top center of the
printer page
Press the purple paper thickness adjustment lever down. (See Loading,
paper, page 15-3.)
Printing Too Dark or Too Light Make sure your ink cartridges are fresh. Cartridges are good up to two
years, after that the ink may become clogged. Cartridge expiration dates are
printed on the package. Make sure the Printer Driver matches the type of
paper you are using (see 15-1.). Try using recommended special paper (see
Chapter 3). The recommended environment for your MFC is between 50°F
to 95°F.
Printing Appears Dirty or Ink Seems
to Run
Make sure you are using the recommended paper (see Chapter 3). Don’t
handle the paper until the ink is dry.
The recommended environment for your MFC is between 50°F to 95°F.
White Lines in Text or Graphics Clean the print head (see Cleaning the print Head, page 24-8.).
Stains Appear on the Reverse Side or
at the Bottom of the Page
Make sure the Printer Platen and Pick Up Roller are not dirty with ink mist.
(See page 24-13).
Vertical Black Lines When Receiving The sender’s scanner may be dirty. 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 Customer Service at 1-800-284-4329
(USA).
Phone Line or Connections
MFC Does Not Answer When Called Make sure the MFC is in the correct receiving mode for your setup (either
MANUAL, FAX, FAX/TEL or TAD). 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. Connect a standard telephone handset to the MFC
telephone jack. If there is no ringing when you call your MFC, call your
Telephone Company to check the line.
No Dial Tone on the Handset Check telephone line cord connections at the MFC and wall jack. Check
that the handset is connected to the MFC’s handset jack. Test the wall jack
with another single line telephone. If no dial tone on the wall outlet, call
your Telephone Company.
Sending Faxes
Poor Transmitting Quality Try changing your resolution to FINE or SUPERFINE. 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 24-12.).
