Hi Silv,

I can understand electronic devices can create confusion when they do not work the way they are designed for. I appreciate your time in trying to fix the printer by yourself.

I would like you to try the below mentioned steps before coming to a conclusion:

Unplug the power cord, adapter from the printer, press and hold the power button on the printer for 20 seconds. This will remove the static power from the printer.

Please try a good adapter and power cable and check. If the problem persists the printer needs to be replaced.

In case the printer has active warranty, please private message the system service tag, contact number and registered owner’s name.
