Case H: Shared voice/fax line with computer modem
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.)
