Welcome to the HP support community.
If the phone line is shared with your voice calls, select a number of rings that provides enough time for you to answer the phone before the printer picks up the call.
-
Get a telephone cord. Make sure it is a cord with two wire leads, not four.

-
Connect the phone cord to the wall jack and to the 1-LINE jack on the back of the printer.

-
If you have an answering machine, connect a phone cord to the machine and to the 2-EXT jack on the back of the printer to allow your answering machine to record voice calls without fax noises.


-
Set up fax settings and preferences. The HP software includes guided fax setup tools, or you can navigate to the Fax or Setup menus on the printer control panel to change settings.
-
Rings to answer: When the phone rings, the printer waits and counts the number of telephone rings before it answers the call.
-
If the phone line is shared with your voice calls, select a number of rings that provides enough time for you to answer the phone before the printer picks up the call.
