HP Photosmart 7510 suddenly lost power

[AliOk]

My printer was working brilliantly, then suddenly between photos, it turned off and I could not turn it back on. It's not the plug or plug point, so something in the printer has suddenly stopped working. Any ideas gratefully received!

Hi! @AliOk, Thanks for stopping by HP forums!

I understand that you are unable to turn on your printer.

Don't worry I will try to help you out.

Did you make any changes to your printer?

Please try the steps recommended below.

Unplug the printer to reset the internal power module, plug another appliance into the wall outlet to test the power, and then reconnect the printer.
Disconnect the power cord from the rear of the printer.
Unplug the power cord from the wall outlet, power strip, or surge protector.
While the printer is unplugged, plug another appliance into the wall outlet, and then turn it on to make sure the outlet works.
If the wall outlet does not work, plug the printer into an outlet that does work. Do not use a power strip or surge protector.
If the wall outlet works, continue with these steps.
After the printer has been disconnected for at least 60 seconds, reconnect the power cord to the rear of the printer.
Plug the power cord directly into the wall outlet. Do not use a power strip or surge protector.
Check the rear of the printer and the ink cartridge access area to see if the internal power module has an indicator light.
If the internal power module has a light, the light is on, and the printer turns on, you can stop troubleshooting.

Refer this article to further troubleshoot no power issues.

If the issue still persists it is a hardware issue, please contact HP support for service options.
