Case J: Shared voice/fax line with computer dial-up modem and answering
If you receive both voice calls and fax calls at the same phone number, and you also
have a computer dial-up modem and answering machine connected on this phone
line, set up the HP All-in-One as described in this section.
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 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.)

Unplug your answering machine from the telephone wall jack, and connect it to
the port labeled 2-EXT on the back of the HP All-in-One.
If you do not connect your answering machine directly to the HP All-
in-One, fax tones from a sending fax machine might be recorded on your
answering machine, and you probably will not be able to receive faxes
with the HP All-in-One.
Using the phone cord supplied in the box with the HP All-in-One, connect one
end to your telephone wall jack, then connect the other end to the port labeled 1-
LINE on the back of the HP All-in-One.
If you do not use the supplied cord to connect from the telephone
wall jack to the HP All-in-One, you might not be able to fax successfully.
This special phone cord is different from the phone cords you might
already have in your home or office.
(Optional) If your answering machine does not have a built-in phone, for
convenience you might want to connect a phone to the back of your answering
machine at the "OUT" port.
If your answering machine does not let you connect an external
phone, you can purchase and use a parallel splitter (also known as a
coupler) to connect both the answering machine and telephone to the
HP All-in-One. You can use standard phone cords for these connections.
If your 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, the HP All-in-One will not be able to receive faxes.

10. Run a fax test.
When the phone rings, your answering machine will answer after the number of rings
you have set, and then play your recorded greeting. The HP All-in-One monitors the
call during this time, "listening" for fax tones. If incoming fax tones are detected, the
HP All-in-One will emit fax reception tones and receive the fax; if there are no fax
tones, the HP All-in-One stops monitoring the line and your answering machine can
record a voice message.
