Case K: Shared voice/fax line with computer dial-up modem and voice mail
If you receive both voice calls and fax calls at the same phone number, use a
computer dial-up modem on the same phone line, and subscribe to a voice mail
service through your telephone company, set up the HP All-in-One as described in
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 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 up 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 you do not use the supplied cord to connect from the telephone

This special phone cord is different from the phone cords you might
already have in your home or office.
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.
