How do I set up fax on the HP OfficeJet 4650?

Connect one end of a phone cord to the phone wall jack and the other end to the port labeled 1-LINE on the back of the printer. If you have a DSL/ADSL service, connect a DSL/ADSL filter between the 1-LINE port and the phone wall jack. To test the fax setup, touch Fax on the Home screen, then touch Setup > Setup Wizard and follow the on-screen instructions. (Page 6)
