[Vishal2780]

My printer has stopped printing. Every time I try to print something, the printer starts flashing a blue screen with an error code B86D1646. the home, back and network signs also keep flashing. Only way to exit this is rebooting. it goes back to the same thing when i try printing again.

Welcome to the HP support community.

I understand that you are getting a B86D1646 error on the printer, follow these steps to fix the issue.

Perform a power reset

1. Turn on the printer, if it is not already on.
2. Wait until the printer is idle and silent before you continue.
3. With the printer turned on, disconnect the power cord from the rear of the printer.
4. Wait at least 30 seconds.
