Okidata C3200N
It would help if you said where the paper jam was. However the fact that it was ok until you cleared the jam indicates you have knocked something out of place. Its just possible one of the high voltage contact springs that touch the drums has stuck in and no longer makes contacts with one of the drums. Make sure all the semi circular springs move in and out freely. Also check the led heads in the top cover. Make sure all the cables are seated in the heads ok. Make sure all the heads are in the same position and one has not turned around. Retrace your steps as your drums seem to be problem.
