Re: Printer unplugged by accident. Now in Shut Mode for over an hour

Hi

Welcome to the HP Support Community. I'd be happy to assist you. Let us try these steps to resolve this issue:

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. Wait until the printer is idle and silent before you proceed.

Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

Also, try to perform a power drain

Unplug the printer and hold the power button down for 10-12 seconds and then release it.

Try to power ON the printer.

Hope this helps! Keep me posted.
