To set up your HP all-in-one to a computer with one phone port
Find the phone cord that connects from the back of your computer (your PC
modem) to a telephone wall jack. Disconnect the cord from the telephone wall jack
and plug it into the parallel splitter on the side with two phone ports.
Using the phone cord supplied in the box with your 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 your HP all-in-one.
If you do not use the supplied cord to connect from the telephone
wall jack to your 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. If the supplied phone cord is too short, see

Using another phone cord, connect one end to the port labeled "2-EXT" on the
back of your HP all-in-one. Connect the other end of the phone cord to the parallel
splitter on the side with the single phone port.
Unplug your answering machine from the telephone wall jack, and connect it to the
parallel splitter on the side with two phone ports.
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 your HP all-in-one.
(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 PC modem software is set to receive faxes to your computer automatically,
turn off that setting.
If you do not turn off the auto fax receive setting in your PC
modem software, your HP all-in-one will not be able to receive faxes.
Set up the HP all-in-one to answer incoming calls automatically. Press the

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

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
