Printer Repair Questions? Ask IT Technicians for Answers ASAP
Hi there and welcome
Can you unplug the power to the printer (so remove the printer power cable from the power socket).
Let it sit for 10 minutes to drain all residue power.
Then connect the power, turn on the printer and tell me if it now functions please.
Can you put the original Toner back in that was in it before this problem started and tell me if you get the error with this still please.
