Fax over Internet Protocol (FoIP)

You may subscribe to a low cost phone service that allows you to send and receive faxes
with your device by using the Internet. This method is called Fax over Internet Protocol
(FoIP). You probably use a FoIP service (provided by your telephone company) if you:

Dial a special access code along with the fax number, or

Have an IP converter box that connects to the Internet and provides analog phone
ports for the fax connection.

NOTE: You can only send and receive faxes by connecting a phone cord to the port
labeled "1-LINE" on the device. This means that your connection to the Internet must
be done either through a converter box (which supplies regular analog phone jacks
for fax connections) or your telephone company.

Some Internet faxing services do not work properly when the device is sending and
receiving faxes at high speed (33600 bps) or when sending color faxes. If you experience
problems sending and receiving faxes while using an Internet fax service, use a slower
fax speed and only send black-and-white faxes. You can do this by using a lower Fax
Speed setting. For information on changing this setting, see
