I received a message on the display about a paper jam or a blocked print head assembly

The wrong measurements are showing in menus on the display

The HP All-in-One will not turn on

Cause: The HP All-in-One is not properly connected to a power supply.

Solution:

Make sure the power cord is firmly connected to both the HP All-in-One and the power source. Plug the power cord into a grounded power outlet, surge protector, or power strip.

Troubleshooting

1Power connection

2Grounded power outlet

If you are using a power strip, make sure the power strip is on. Or, try plugging the HP All-in-One directly into a grounded power outlet.

Test the power outlet to make sure it is working. Plug in an appliance that you know works, and see if the appliance has power. If not, then there might be a problem with the power outlet.

If you plugged the HP All-in-One into a switched outlet, make sure the switch is on. If it is switched to on but still does not work, then there might be a problem with the power outlet.

Cause: You pressed the On button too quickly.

Solution: The HP All-in-One might not respond if you press the On button too quickly. Press the On button once. It might take a few minutes for the HP All-in-One
