hp 6978 pro fax line noise test fail

HP Recommended
HP 6978 pro
Microsoft Windows 10 (64-bit)

My HP 6978 pro shows a Failed on the Fax test report. When 2-3 weeks ago it worked fine. I have checked the phone line with a phone and it works fine. When we run the test it seems that the tone is very short before going into a busy signal. There is no answering machine, and the rings are set on 6. Our carrier is Cox.

Such an error relies with the fax line condition only, such issues will unlikely be visible while speaking on the line, but yet prevent a successful data delivery for faxing.


Try changing a phone cable and check again, if it doesn't change you should contact your phone provider to improve the phone line condition.
