Solution 1: 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.
To change the ECM setting from the control panel
1. Press Setup.
2. Press the down arrow button to highlight Advanced Fax Setup, and then press
OK.
The Advanced Fax Setup menu appears.
3. Press the down arrow button to highlight Error Correction Mode, and then press
OK.
The Error Correction Mode menu appears.
4. Press the down arrow button to highlight Off or On.
5. Press OK.
Cause: The phone line connection was noisy. Phone lines with poor sound quality
(noise) can cause faxing problems.
If this did not solve the issue, try the next solution.
Solution 2: Increase the fax resolution
Solution: For the highest-quality fax, change the fax resolution to Fine, Very
Fine (if available), or Photo.
Cause: The fax resolution setting was set to a low resolution, such as Standard.
