Usually this is caused by a poor telephone connection. If your copy looks good,
you probably had a bad connection, with static or interference on the telephone
line. Ask the other party to send the fax again.
Poor print quality See Improving the print quality on page 134.
Vertical black lines when receiving The corona wires for printing may be dirty. Clean the corona wires on the four
drum units. (See Cleaning the corona wires on page 158.)
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 your dealer for service.
Received faxes appear as split or
blank pages.
If the received faxes are divided and printed on two pages or if you get an extra
blank page, your paper size setting may not be correct for the paper you are using.
