Case J: Shared voice/fax line with computer modem and answering machine
If you receive both voice calls and fax calls at the same phone number, and you also have a computer
modem and answering machine connected on this phone line, set up the HP device as described
in this section.
NOTE: Since your computer dial-up modem shares the phone line with the HP device, you
cannot use both your modem and the device simultaneously. For example, you cannot use the
HP device for faxing while you are using your computer dial-up modem to send an e-mail or
access the Internet.
