Communication problems over a USB connection
If the HP All-in-One and computer are not communicating with each other, try the
following:
• Look at the On light located on the front of the HP All-in-One. If it is not lit, the HP All-
in-One is turned off. Make sure the power cord is firmly connected to the HP All-in-
One and plugged into a power outlet. Press the On button to turn on the HP All-in-
One.
• 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.
