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:

•Check the USB cable. If you are using an older cable, it might not be working properly. Try connecting it to another product to see if the USB cable works. 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
