Before you begin

Complete the printer setup before connecting the fax service.


When connecting the printer to the telephone jack, use the phone cord and adapters that shipped with the printer.

Do not use other phone cords as it might cause problems with fax transmission.


In countries/regions that use serial telephone systems, an adapter is shipped with the printer. Use the adapter to connect other telecom devices to the same telephone jack that the printer is connected to.

Depending on the phone connection type, you might need a line-splitter and additional two-wire phone cords to complete the fax setup.

To identify the fax port and the telephone line-out port, look for the following icons on the rear of the printer:

Step one: Identify the phone connection type

Review the following equipment and service types to determine which setup method to use. The method used depends on the equipment and services already installed on the phone system.


The printer is an analog device. HP recommends using the printer on a dedicated analog telephone line.

  • Dedicated phone line: The printer is the only piece of equipment or service connected to the phone line

  • Voice calls: Voice and fax calls use the same phone line

  • Answering machine: An answering machine answers voice calls on the same phone line used for fax calls

  • Voice mail: A voice-mail subscription service uses the same phone line as the fax

  • Distinctive ring service: A service from the telephone company that allows several phone numbers to be associated with one phone line, and each number has a different ring pattern; the printer detects the ring pattern assigned to it and answers the call

  • Computer dial-up modem: A computer uses the phone line to connect to the Internet through a dial-up connection

  • DSL line: A digital subscriber line (DSL) service from the telephone company; this service might be called ADSL in some countries/regions

  • PBX or ISDN phone system: A private branch exchange (PBX) phone system or an integrated services digital network (ISDN) system

  • VoIP phone system: Voice over Internet protocol (VoIP) through an Internet provider

Step two: Set up the fax

Choose one of the options below that best describes the environment in which the printer will be sending and receiving faxes, and then follow the steps provided to set up the fax.
