Problem

When I connect a USB cable between the printer and my computer, I get an error saying YOU HAVE CONNECTED YOUR COMPUTER TO THE PRINTER’S FRONT USB PORT.

Possible cause

You have connected your computer to the camera port on the front of the printer. This port should only be used to connect an HP direct-printing digital camera to the printer.

4Reinstall the printer software. For instructions, see the Software Setup & Product Support booklet.
