HP Officejet J5730 - Case J: Shared voice/fax line with computer dial-up modem and answering machine

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.)

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

To set up the HP All-in-One on the same phone line as a computer with two phone
ports

1.

Remove the white plug from the port labeled 2-EXT on the back of the HP All-in-One.

2.

Find the phone cord that connects from the back of your computer (your computer
dial-up modem) to a telephone wall jack. Disconnect the cord from the telephone wall
jack and plug it into the port labeled 2-EXT on the back of the HP All-in-One.

3.

Unplug your answering machine from the telephone wall jack, and connect it to the
“OUT” port on the back of your computer modem.
This allows a direct connection between the HP All-in-One and your answering
machine, even though the computer modem is connected first in line.

NOTE:

If you do not connect your answering machine in this way, fax tones from

a sending fax machine might be recorded on your answering machine, and you
might not be able to receive faxes with the HP All-in-One.

4.

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.

NOTE:

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.

5.

(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.

NOTE:

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.

6.

If your modem software is set to receive faxes to your computer automatically, turn
off that setting.

NOTE:

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.

7.

Turn on the Auto Answer setting.

8.

Set your answering machine to answer after a low number of rings.

9.

Change the Rings to Answer setting on the HP All-in-One to the maximum number
of rings supported by your device. (The maximum number of rings varies by country/
region.)

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.
