Error message: Fax hardware is missing or not seated

How do I fix the Error message: Fax hardware is missing or not seated. My fax machine is not working!

Hi @Shello1,

Welcome to the HP Support Community.

I understand that the printer displays “Fax hardware is missing or not seated” and the fax function is not working. This message can indicate that the printer is not detecting its internal fax hardware correctly.

Please try a power reset:

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Unplug the power cord from the wall outlet.
3. Wait for 60 seconds.
4. Reconnect the power cord directly to a wall outlet, and then reconnect it to the printer.
5. Turn on the printer if it does not start automatically, and check whether the error returns.
    

If the message remains, please provide the following details so we can check the correct HP guidance for your printer:

• What is the exact HP printer or fax machine model?
• Does the error appear immediately at startup or only when sending or receiving a fax?
• Did the issue begin after a firmware update, power interruption, printer movement, or repair?
• Can the printer still print, scan, and copy normally?
• Have you already tried any troubleshooting steps?

Please do not open the printer or attempt to reseat any internal fax components. If the error continues after the power reset, the printer might require inspection by HP Support or an HP-authorized service provider.
