Question about HP 640 Inkjet Fax Machine
The error message I received was 007. If this is your error message.... then keep reading. The error message relates to the power from the fax machine. Look at the line cord from the fax machine. The little plastic end should show 2 metal connectors for the wires. If yours shows 4 as mine did, it's as simple as changing to a 2 wire cord. You could call Vonage and they will ask you if yours is a 2 or 4 wire, but if you don't know what to look for..... since the wires and connectors are the same size, you might think yours is 2 when it's 4 as I did. Good luck!

All fax machines are ANALOG devices. They are designed to work on POTS (Plain Old Telephone System). Any other condition is a **** shoot.
