Test your fax machine

Send a one page black and white text fax to 1-888-hpfaxme (1-888-473-2963).
When your fax is received by the HP Test Fax Service, we will generate a return fax to you within five minutes confirming that we received your fax. This verifies that you can both send and receive a fax with your fax machine.

If you do not receive a return fax within 5-7 minutes, there may be a problem with the setup of your fax machine. Consult the user manual that came with the product for proper setup and configuration.

NOTE: The most common cause of failure is that the fax number set in the Fax Header on the machine does not match the number of the phone line connected to the fax. Also, ensure that the fax header contains the full 10-digit telephone number of the fax machine, including the area code.
