How do I set up the HP OfficeJet 4650 to receive faxes automatically?

By default, the printer automatically answers incoming calls and receives faxes. To confirm or enable this, touch Fax on the Home screen, then touch Setup, then Preferences, and ensure the Auto Answer option is turned on. Note that if you have subscribed to a voice mail service on the same phone line, you cannot receive faxes automatically and must respond to incoming fax calls in person. (Page 7)
