Note You cannot receive faxes automatically if you have a voice mail service at
the same phone number you use for fax calls. You must receive faxes manually;
this means you must be available to respond in person to incoming fax calls. If
you want to receive faxes automatically instead, contact your telephone company
to subscribe to a distinctive ring service, or to obtain a separate phone line for
faxing.
Since your computer dial-up modem shares the phone line with the HP All-in-One, you
will not be able to use both your modem and the HP All-in-One simultaneously. For
example, you cannot use the HP All-in-One for faxing if you are using your computer dial-
up modem to send an e-mail or access the Internet.
There are two different ways to set up the HP All-in-One with your computer based on
the number of phone ports on your computer. Before you begin, check your computer to
see if it has one or two phone ports.
● If your computer has only one phone port, you will need to purchase a parallel splitter
(also called a coupler), as shown below. (A parallel splitter has one RJ-11 port on
the front and two RJ-11 ports on the back. Do not use a 2-line phone splitter, a serial
splitter, or a parallel splitter which has two RJ-11 ports on the front and a plug on
the back.)

● If your computer has two phone ports, set up the HP All-in-One as described below.
