My printer will not fax

[polarbar]

I  have an HP all in one printer. HP Officejet Pro 6978.. It used to fax and now it does not. I need to get that function going again as it is important to my business.  I belong to the ink program  and I believe changing ink cartridges may have helped to create the issue. Help.I use the fax function, it dials and always comes back saying "no answer".  I know there should be working on the VA's website/

Hi @polarbar,

Welcome to the HP Support Community

I understand you are not able to send/receive a fax issue with your HP OfficeJet Pro 6978 All-in-One Printer series. Not to worry I will help you to get a resolution to resolve the issue.

Let us try these steps:

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Click here to check the document  check the FAQ as well 

Click here  HP printers - Using Mobile Fax (HP Smart app)

Click here  HP printers - Use HP Digital Fax to receive faxes to a computer or email

Check the fax connections. Use a 2-wire fax cable to connect to the printer from the phone jack. 

On the printer screen, go to  Fax > Setup > Tools > Run fax test

Check the result.

Send a one-page black and white text fax to 1-**bleep**-HPFaxme (1-**bleep**-473-2963). When the service receives your fax, a return confirmation fax is sent within five minutes. This verifies that you can both send and receive a fax.

I hope this helps! Keep me posted.
