Randomly getting Error 79 when sending fax from the glass. Turning off and on doesn't always work.  No other issues with printing at this point.

Fax error 79

Welcome to HP support community.

 

Update the printer firmware

Refer this HP document for the steps to update the firmware:- Click here

 

Turn off Error Correction Mode: Turning off this feature can improve sending success when the phone line quality is poor, but the image quality of the received fax might be unsatisfactory. If this must be turned off to send faxes, have the phone service provider check the line quality.

 

Check the connection

  • Call the fax number you are sending to from a phone: If you do not hear fax tones, the receiving fax machine might be turned off or disconnected.

  • Confirm the fax setup: There are two phone ports on the rear the printer labeled 1-Line and 2-Ext. Connect the phone line to the 1-Line port, and connect the answering machine to 2-Ext.

Cheers.
