About fax setup

Before you begin troubleshooting, review the following information about fax setup.

Fax configuration

Make sure to set up or review your current parameters and preferences for faxing. Using the correct settings for your situation can prevent many issues.

For example, you can set up send options and receive options. You can also specify reporting options, such as whether to print a notification report after a failed fax job, or whether to print a confirmation report after a successful fax job.

To access the Fax Setup menu from the printer control panel, touch the Setup icon Setup icon, and then touch Fax Setup.

Analog vs. digital environments

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

For a digital environment, such as DSL, PBX, ISDN, or VoIP, make sure to use the correct filters and configure the digital settings correctly. For more information, contact the digital service provider.
