that plugs into a telephone wall jack.) If you are using a splitter, remove it and connect the product
directly to the telephone wall jack.
Cause: You were using a phone line splitter.
If this did not solve the issue, try the next solution.
Solution 6: Make sure the telephone wall jack works properly
Solution: Try connecting a working telephone and phone cord to the telephone wall jack you
are using for the product and check for a dial tone. If you do not hear a dial tone, call your local
telephone company for service.
Cause: The telephone wall jack was not working properly.
If this did not solve the issue, try the next solution.
Solution 7: 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.
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.
