DIFFICULTY SUGGESTIONS
Phone Line or Connections
The MFC does not
answer when called. Make sure the MFC is in the correct receiving
mode for your setup (either
FAX ONLY ,
EXT.TEL/TAD or MANUAL (for Distinctive
Ring). 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.
Sending Faxes
Transmitting quality is
poor. Try changing your resolution to FINE or
SUPERFINE (See
Fax Resolution,
page 6-7). Make
a copy to verify the MFC’s scanner operation.

prints “Results:NG”. There is probably temporary noise or static on the
phone line. Try sending the fax again. If the
problem continues, call the telephone company to
check your phone line.
The receiving party says
the picture is not clear. Sometimes the resolution mode you chose when you
sent your fax was not appropriate. Send the fax again,
but try using the
FINE or SUPERFINE mode. Also,
your MFC’s scanner may be dirty, so try cleaning it.
(See pages 20-17)
The receiving party says
vertical streaks appear
on the faxes they
receive. Your MFC’s scanner may be dirty or the receiving
party’s print head may be dirty. Clean your scanner
(see pages 20-17), and then make a copy to check
if the problem was caused by your machine.
