thank you
thats what i suspected, so i removed the black IU and saw same toner/dev!! rolling on the drum, cleaned it and slide it back in
now its working fine again!
except of the paper ejection gear!

Cleaning excess Dev off the drum will only be a temporary fix - it will come back and will most certainly affect c/q, you will need to replace the unit. There is a mod bulletin for the k drum as well that you can find on the km site
