I recently brought a HP Officejet Pro 8500 (910n) and cannot use it to fax. The printer's FAX troubleshooting told me the following. That I had two lines (4 wire) system in my house. To be able to fax I needed a 4 wire to 2 wire adapter or connection cable. The printer comes with a standard 2 wire (two center wires only) plug.
Has anyone ever had this problem before? Has anyone ever heard of a 2 wire to 4 wire adapter or cable?
The troubleshooter also had the United States listed as one of the countries having this problem.
