If you have a fax line on which you receive no voice calls, and you also have a computer modem connected on this line, set up the printer as described in this section.
Note
If you have a computer dial-up modem, your computer dial-up modem shares the phone line with the printer. You cannot use both your modem and the printer simultaneously. For example, you cannot use the printer for faxing while you are using your computer dial-up modem to send an email or access the Internet.
