Resolve Windows 10 related issues for your HP computers or printers by HP Windows 10 Support Center
I cannot send or receive a fax. When I run the test, everything passes except the dial ton detection. It says "A dial tone was not detected." I plugged in a new cord and it still is not working.
Welcome to HP Forums, this is a great place to get support, find answers and tips.
Thank you for posting your query, I'll be more than glad to help you.
I understand that you are unable to send or receive fax from your HP Officejet Pro 8620 e-All-in-One Printer.
This issue could occur if there is an issue with the phone line.
Hence, to isolate the issue, I suggest that you disconnect the printer from the wall jack and connect a normal telephone and check if you get a dial tone.
If there is a dial tone when you connect the normal telephone to the wall jack, I suggest that you follow the steps mentioned in the link: How to Fax
Note: Please follow the steps mentioned in the sublink "Set up the printer for faxing" in the above document.
Let me know how this works.
You have a good day ahead.
