Solution 1: Check the receiving fax machine for problems
Solution: Try calling the fax number from a telephone and listen for fax tones. If
you cannot hear fax tones, the receiving fax might not be turned on or connected, or
a voice mail service could be interfering with the recipient's phone line. You can also
ask the recipient to check the receiving fax machine for any problems.
Cause: The receiving fax machine was having problems.
Solution 2: Check the phone line for noise
Solution: 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 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. If the problem persists, turn Error
Correction Mode (ECM) off and contact your telephone company.
