Solution 2: Lower the fax resolution
Solution: For faster transmission, use Standard resolution. This setting provides the fastest possible
transmission with the lowest quality of fax. The default resolution is Fine, which can take longer to send.
Cause: The document contained a lot of graphics or had very fine detail.
If this did not solve the issue, try the next solution.
Solution 3: 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

Correction Mode (ECM) off and contact your telephone company.

Solution 4: 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 5: Increase the fax speed
