There are two different ways to set up the product 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
NOTE: 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 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.)

modem) to a telephone wall jack. Disconnect the cord from the telephone wall jack and plug it

If you do not use the supplied cord to connect from the telephone wall jack to the device,
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.

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 product. You can use standard phone cords for these
6. If your modem software is set to receive faxes to your computer automatically, turn off that
NOTE: If you do not turn off the automatic fax reception setting in your modem software,
the HP product 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 product to the maximum number of rings supported
by the product. (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 product monitors the call during this time, "listening" for
fax tones. If incoming fax tones are detected, the product will emit fax reception tones and receive
the fax; if there are no fax tones, the product stops monitoring the line and your answering machine
can record a voice message.
If you encounter problems setting up the device with optional equipment, contact your local service
provider or vendor for further assistance.
