When I started colour printing (in the last century) I used a JOBO and got all descriptions of problems and probably the same as you are getting now. I changed over to a Nova Slot Processor and the problem disappeared. It WAS contamination caused by not washing and drying the drum out properly after each print. Doing it after each print was tedious and slow, the NOVA is much quicker and more reliable, you only have to rinse off the clips that hold the paper.
