Printing Received Faxes
Condensed print and white
streaks across the page or the
top and bottom of sentences
are cut off.
This can be caused by static or interference on the telephone line. You
can make a copy using the Black Start key to see if the same problem
occurs. If the copy looks good then the problem is probably the phone
line and not your machine.
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.
