Fax over Internet Protocol

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

TIP: Support for traditional fax transmission over any Internet protocol telephone
systems are often limited. If you experience problems faxing, try using a slower fax
speed or disabling the fax error-correction mode (ECM). However, if you turn off
ECM, you cannot send and receive color faxes. (For more information about
changing the fax speed, see Set the fax speed. For more information about using
ECM, see Set the Error Correction Mode.

If you have questions about Internet faxing, contact your Internet faxing services
support department or your local service provider for further assistance.
