This printer recently started giving all three of these error messages together. Every time I power on it says improper shutdown, and when I try to do anything it says printer failure. Also gives a message to check the tray and clear any stuck paper. I’ve dismantled everything and it’s clear. The carrier moves. I’ve restored to defaults (twice), power cycled (twice), bypassed surge protector, updated firmware, and reseated cartridges. Nothings changed it. This printer worked OK a few weeks ago, outside of a badly uneven print, but it at least worked. Any suggestions?
thanks
