Hi there jrlead, welcome to the forums
I saw your post about the fax error code 339 you are seeing and wanted to respond to you with the definition. Below is a screen shot that will explain it. I hope this helps you! If the error continues, I would suggest calling HP to see what your options are with them. I will include their contact info below.

Interpreting Error Codes in Fax Communication Error or Fax History Reports
If you are calling within North America, the number is 1-800-474-6836 and for all other regions: click here.
Have a great day
