Cause: You are using a phone line splitter.

Solution: A phone line splitter can cause faxing problems. (A splitter is a two-cord connector that plugs into a telephone wall jack.) Try removing the splitter and connecting the HP All-in-One directly to the telephone wall jack.

Troubleshooting

Cause: The telephone wall jack is not working properly.

Solution: Try connecting a working telephone and phone cord to the telephone wall jack you are using for the HP All-in-One and check for a dial tone. If you do not hear a dial tone, call your local telephone company for service.

Cause: The phone line connection is noisy. Phone lines with poor sound quality (noise) can cause faxing 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, turn Error Correction Mode (ECM) off and contact your telephone company.
