shooting
Received images are
distorted.
• Noise on the telephone line may cause distortion.
Have the other party try sending the document again.
• ECM mode (see page 50) will help prevent distortions
due to line noise. Note that ECM mode must be
turned on in the other machine as well.
• Make a copy or print a report on your fax machine. If
the copy or report is also distorted, your fax machine
may need service.
The quality of copies is
poor and/or dark vertical
lines appear.
• Any dirt or material on the scanning glass will cause
spots to appear on copies and transmitted faxes.
Clean the scanning glass as explained on page 90.
The power is on, but no
reception takes place.
• Make sure that the telephone line cord is plugged into
the TEL. LINE jack, and not the TEL. SET jack.
