HP printers are designed specifically for use with traditional analog phone services. If you are in

a digital phone environment (such as DSL/ADSL, PBX, or ISDN), you might need to use digital-to-

analog filters or converters when setting up the printer for faxing.
NOTE: HP does not guarantee that the printer will be compatible with all digital service lines or

providers, in all digital environments, or with all digital-to-analog converters. It is always

recommended that you discuss with the telephone company directly for the correct setup options

based on their line services provided.

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.

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

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 Send a fax in 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.
