I have an HP ENVY PRO 6400 SERIES printer. Love it. It has been working great and has not failed me. I leave the printer on 24/7. Nothing has happened in all my years of using HP printers. However, I came into my office one day and all the lights on the printer were flashing, randomly. Scared me. I unplugged the printer for the day. The next day I plugged the printer back into the wall outlet and it commenced working beautifully again. No problems. Hasn't happened since. I just unplug it at night now. But, what would cause the sudden flashing of all lights on the printer?
