@TomAA, have you tried doing a hard reset with the printer?
Hard Reset:
Unplug the power cord from the printer and wall
Take out the toner/cartridges
Wait 30 sec
Plug the power cord back into the printer and wall (Make sure the printer is plugged into the wall and not a surge protector)
Insert the toner/cartridges back into the printer
Let me know the outcome
