Exlamation mark is blinking

[SonderMilan]

Hi the exlamation mark on the printer is blinking and we cannot use it. We tried turning it off and on again, we tried unpluging the power cord and waiting a few minutes and turn it back again, but still nothing...the printer is HP LaserJet M140w

Hi @SonderMilan 

Welcome to the HP Support Community

I understand you are facing an issue with your Exclamation point showing on my HP Laser jet mfp m140w. Not to worry I will help you to get a resolution to resolve the issue.

Let's perform a power drain: 

• 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.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• 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.
• Turn on the printer and wait till warm-up period finishes and the printer is idle
