Press the power button to turn on the product or to deactivate the Auto Power Down mode.

Check the power-cable connections.

Make sure that the line voltage is correct for the product power configuration. (See the label on

the back of the product for voltage requirements.) If you are using a power strip and its voltage is

not within specifications, plug the product directly into the wall. If it is already plugged into the

wall, try a different outlet.

If none of these measures restores power, contact HP Customer Care.

Check the cable connection between the product and the computer. Make sure that the connection

is secure.

Make sure that the cable itself is not faulty by using a different cable, if possible.

If the product is connected to a network, check the following items:

●

Check the light next to the network connection on the product. If the network is active, the

light is green.

●

Make sure that you are using a network cable and not a phone cord to connect to the

network.

●

Make sure the network router, hub, or switch is turned on and that it is working correctly.

●

If your computer or the product is connected to a wireless network, low signal quality or

interference might be delaying print jobs.

If you are using a personal firewall system on the computer, it might be blocking communication

with the product. Try temporarily disabling the firewall to see if it is the source of the problem.
