Unable to send or receive fax using HP8620 Printer. No dial tone when phone goes through printer.

[Daisy39]

Fax has been working fine for years.  Now no dial tone on phone, but OK when plugged directly into the phone jack.  Bought a new phone.  Problem is NOT with the phone.  Is there a way to test the printer to see if the fax function is working?  Does something need to be updated?

@Daisy39, Welcome to the HP Support Community!

Run a fax test on the printer

Go to Setup > Fax setup > Fax tools > Run fax test

Note: Without an active phone line/dial tone to the printer, the test will fail and the fax will not work.

Check the connections

Make sure you are using a 2 Wire phone cable.

Are you using a dedicated fax line or is it a shared line?

Refer to this document for more info on troubleshooting fax issues.

Let me know how this goes.

I could not test the fax function.  Talked with our computer guy and concluded the printer was damaged by a lightening strike.  He said they have had a number of computers that were "hit."  (We have had a lot of thunder storms recently.)  The charge comes in through the phone line - through the printer and damaged the fax function in the printer.  That would explain why there wasn't a dial tone on the phone since the phone line was routed through the printer to the phone.  Another phone connected directly to the phone jack did work.
