Question about HP 640 Inkjet Fax Machine
EXT. Phone To RX displayed in window....can't recieve in coming faxes
You cannot use a four wire cable to connect the fax to the wall. You must use a two wire cable, like the one that came with the machine. BTW, that means you can't you the EXT port to connect a two line phone or answering machine.
