General print quality is
poor.
It is important to select a paper that is appropriate for
the thermal transfer printer in your fax. We
recommend using laser quality paper that has a very
smooth finish. Copier paper will work, but it
sometimes tends to yield a lighter print quality.
The received document is
faint.
Ask the other party to send higher contrast
documents. If the contrast is still too low, your fax may
have a problem. Make a copy to check it.
Received images are
distorted.
Noise on the telephone line may cause distortion.
Have the other party try sending the document again.
The print head may be dirty. See Fax print head in
Chapter 10.
Make a copy of another document on your fax. If the
copy is also distorted, your fax may have a problem. If
the problem persists, call for service.
The quality of copies is
poor and/or black spots
appear.
Any dirt or material on the scanning glass will cause
spots to appear on copies and transmitted faxes.
Clean the fax print head and the scanning glass as
explained in Chapter 10.
Reception/copying is
interrupted.
If reception or copying takes place continuously for a
long time, the print head may overheat. Turn off the
power and let it cool down.
A received document or
copy prints out in strips.
Make sure the operation panel and the printer
compartment cover under the operation panel are
completely closed (press down on both sides of
each). (To close the printer compartment cover, grasp
the top of the operation panel and pull to open it, and
then press down on both sides of the printer
compartment cover.)
