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

The corona wires for printing may be dirty. Clean the corona wires on the drum
unit. (See Cleaning the corona wires on page 98.)

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 and Type on page 19.)

Turn on Auto Reduction. (See Printing a reduced incoming fax in Chapter 4 of the
Advanced User's Guide.)

Telephone line or connections

Difficulties

Suggestions

Dialling does not work.

Check for a dial tone.

Change Tone/Pulse setting. (See the Quick Setup 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 Mono Start or Colour Start.

The machine does not answer
when called.

Make sure the machine is in the correct receive mode for your setup. (See
Receive Mode settings on page 35.) Check for a dial tone. If possible, call your
machine to hear it answer. If there is still no answer, check the telephone line cord
connection. If you do not hear ringing when you call your machine, ask your
telephone company to check the line.
