Case K: Shared voice/fax line with computer modem and voice mail
If you receive both voice calls and fax calls at the same phone number, use a
computer modem on the same phone line, and subscribe to a voice mail service
through your telephone company, set up your HP All-in-One as described in this
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 modem shares the phone line with your HP All-in-One, you will
not be able to use both your computer modem and your HP All-in-One
HP Officejet 5600 All-in-One series
simultaneously. For example, you cannot use your HP All-in-One for faxing if you are
using your computer modem to send an e-mail or access the Internet.
There are two different ways to set up your 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.) For additional details, see the
section in the onscreen

If your computer modem software is set to receive faxes to your computer
automatically, turn off that setting.
If you do not turn off the automatic fax reception setting in your
modem software, your HP All-in-One will not be able to receive faxes.
