Printing or receiving faxes
Difficulties Suggestions
 Condensed print
 Horizontal streaks
 Top and bottom sentences are
cut off
 Missing lines
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 117.
Vertical black lines when receiving The corona wire for printing may be dirty. Clean the corona wire. (See Cleaning
the corona wire on page 140.)
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.
(See Paper Size on page 20.)
Turn on Auto Reduction. (See Printing a reduced incoming fax on page 45.)
Telephone line or connections
Difficulties Suggestions
Dialling does not work. Check for a dial tone.
Change Tone/Pulse setting. (See the Quick Guide.)
Check all line cord connections.
Check that the machine is plugged in and switched on.
If an external phone is connected to the machine, send a manual fax by lifting the
handset of the external telephone and dialling the number. Wait to hear the fax
receiving tones before pressing Start.
