I obviously can only speak to my experience, and the instructions they gave me worked.. There was no explanation of why it happened or what happened, but the printer is still working, haven't had the issue again. My students use it almost daily.Obvio...
I had the same problem. I was told to unplug the printer, press the power button five times, wait one minute, and plug it back in. Don't know exactly what this did internally, but the printer powered back on. Hope it helps you.
