from the looks of it you have a problem in the K system. how do the PCU's look?

have had problems with misting caused by the filter system being all full of toner (the ports and tubing from process unit all the way to the slide in filter set needs to be cleaned out)

It looks like waste toner to me, have you checked the waste toner pipe on the back of the machine? Behind the process unit?
