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 on page 52. For more
information about using ECM, see
Send a fax in Error Correction Mode on page 41.
If you have questions about Internet faxing, contact your Internet faxing services support department
or your local service provider for further assistance.
