Cause: The sending fax machine is having problems.
Solution: Ask the sender to check their fax machine for any problems.
Cause: The phone line connection is noisy. Phone lines with poor sound quality
(noise) can cause print quality problems.
Solution: If the failure was due to noise on the phone line, contact the sender to
have them resend the fax. The quality might be better when you try again. You can
check the sound quality of the phone line by plugging a phone into the telephone wall
jack and listening for static or other noise. If the problem persists, contact your
telephone company.
