I dont know about this printer but i had same issue in c8000 and problem was from toner holder cover.it was very tight and toner not move easily.

Open toner supply door
Lose the toner holder, active door sensor by some screw, push the toner by your hand and keep your hand back of toner, and start machine, see toner is moving or not, if moving, wait for a while untill stopped. Than error will gone.
