hp M1212NF three lights on no led display

[MrMoris]

Hello everyone. I have got a laserjet hp m1212nf printer. All three lights are on and there is no led display. It's like the printer is dead. It takes no instructions.

Can anyone help me?

I have been trying to do it for three hours.

@MrMoris,

Welcome to the HP Support Community!

I reviewed your post and I understand that the printer is not working.

Don’t worry, I assure you I will try my best to get this sorted.

Are you getting any error when you print?

Are you able to make a copy?

Meanwhile, I recommend you follow the below steps and check if it helps.

1. With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet. 
2. Remove USB cable, if present. 
3. Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge. 
4. Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer. 
5. Turn on the printer and wait till warm-up period finishes and the printer is idle.

If you continue facing the issue, then update the printer firmware following the steps in the below article.
