How do I set up the fax feature on my HP OfficeJet 6950?

You can set up fax using the HP printer software (recommended) or the printer control panel. On Windows, use the Fax Setup Wizard during software installation, or after installation open the HP printer software, go to the Fax tab, and select Fax Setup Wizard. On OS X, use Basic Fax Settings in HP Utility after installation, or on the control panel touch Fax on the Home screen and then touch Setup. (Page 2)
