If You are Having Difficulty with Your MFC
When the Receiving Party Says the Picture is Not Clear
Sometimes the resolution mode you chose when you sent your fax may not have been
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 page 13-1~2.)
When the Receiving Party Says Vertical Streaks Appear on the Faxes They
Receive:
Your MFC’s scanner may be dirty or the receiving party’s printer head may be dirty.
Clean your scanner, (see page 13-1~2) and make a copy to check if the problem was
caused by your machine.
Vertical Streaks Appear on the Faxes You Receive
Sometimes you may see vertical streaks on the faxes you receive. Either your MFC’s
primary corona wire for printing may be dirty, or the sending party’s fax scanner may
be dirty. Clean your primary corona wire. (See page 13-3.) Make a copy to see if the
vertical streaks are still there.
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.
