• Disconnect from a USB hub or docking station: If you connected the printer through a USB hub or docking station, try connecting the cable directly to a port on the computer.
• Try a different USB cable: Use a different USB cable. HP supports USB cables less than 3 meters (9 ft 10 in) in length.

  If removing other devices resolves the issue, HP recommends installing a powered hub to connect multiple USB devices.
