NOTE: For information on network communication problems, see “Network troubleshooting” on page 158. For information on communication problems involving a memory card, PictBridge camera, or storage device, see “Memory card and front USB port troubleshooting” on page 179.

If the HP All-in-One and computer are USB-connected and are not communicating with each other, try the following:

If you experience problems, the USB cable might need to be replaced. Also verify that the cable does not exceed 3 meters (9.8 feet) in length.

•Check the connection from the HP All-in-One to your computer. Verify that the USB cable is securely plugged into the USB port on the back of the HP All-in-One. Make
