Hi there and welcome
You said you shut it off and turned it on again but I am not sure this is what you did exactly, so if so, please let me know, else please do the instructions below.
Can you please remove the power to the printer (so unplug it from the power socket).
Then wait 10 minutes, connect the power again to the printer, turn it on and tell me please if it is now operating correctly.
Let me know the results please
