NOTE: Since your computer dial-up modem shares the phone line with the printer, you
cannot use both your modem and the printer simultaneously. For example, you cannot use
the printer for faxing while you are using your computer dial-up modem to send an email or
access the Internet.

Shared voice/fax line with computer dial-up modem and answering machine
There are two different ways to set up the printer 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.
NOTE: If your computer has only one phone port, you need to purchase a parallel splitter
(also called a coupler), as shown in the illustration. (A parallel splitter has one RJ-11 port on
the front and two RJ-11 ports on the back. Do not use a two-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.)
