In my opinion, is related to the type of paper you are using. What now, accumulated within the imaging units, the gloss. The Gloss, is gum that the paper has mainly the role of typography. The gloss once inside the units, is glued to the roll of transfer of units.
Leading to such risks, on the copy. Is it normal to be in magenta and cyan, they are the main units online.
To resolve this, you must call the maintenance engineer. Or replace the damaged units.

You are probably using an all purpose paper. Yhis one that has some ink jet properties. These chemicals that prevent the ink jet ink from spidering will leach out in the ricoh machines and breakdown fuser roller, feed rollers, tranfer belts and rollers, as well as get carried to the drum units and affect the cleaning blades. So it is prbably time to get a service tech in and evaluate the whole machine for these potential problems,
