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 165-166.)
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 print head may be dirty.
Clean your scanner, (see pages 165-166) and make a copy to check if the problem was
caused by your machine.

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 167.) Make a copy to see if the
vertical streaks are still there.

Horizontal Streaks
You may get a fax with horizontal streaks or with missing lines. Usually this is caused
by a poor telephone connection. Ask the other party to send the fax again.
Poor Printing Quality
If the printing quality is not at an acceptable level, please replace your drum unit with
a new one.
