    Yes, we have cleaned the PS units with no change in symptoms. However I just now had a new PS unit overnighted based on a loose theory that maybe the PS roller is worn or the bushings and it is affecting the amount of pressure the paper dust remover applies to it. We shall see. The machines range from 300 - 750K . I hate blindly throwing parts at a problem but ya gotta do what ya gotta do.

    750k to 1M is normal yield for the registration assembly.

    Sorry, I can't call it a Paper Stop Assembly when every other manufaturer calls it a registration assembly.

    Call it a Paper Stop, call it Registration Assembly, call it a waste of money. Installed it and didn't do squat. So just to recap...we have abnormal buildup of paper dust/lint on the drum blade causing streaks. Drum blade can be cleaned but streaks come back after a couple days once the buildup occurs again. Have tried aftermarket and OEM paper dust removers, OEM drums and blades, new registration assy. Also tried modifying the paper dust removers to apply more pressure to the reg. roller. Nothing works. Tried vacuuming out waste toner augers as a shot in the dark. Tried higher quaility paper...still the buildup occurs and the streaks return. I think we're cursed.

    Just a shot in the dark, but, are you using OEM toner and DV?

    Yes, OEM toner and DV. I almost wish we weren't just so we would have something else to try. The latest shot in the dark....we found that the ozone filter in the transport area had a section that was plugged with paper dust. For now we just removed the dang thing hoping to suck as much paper dust out of the thing as possible. My head is getting pretty lumpy from banging it against the wall.

    Do you actually see paper dust under the blade, or is this a theory?

    As a not-cleaning problem there are other possibilities........

    Yes, you can actually see the paper dust plain as day. It builds up all along the entire length of the blade but it builds thicker in random areas and causes the streaks. If left to run without cleaning the blade every couple of days it will actually start to wear the drum. As you could imagine this little gem of a problem is costing us a fortune in parts and labor as well as weaking our customer relationships. Now I'm just whining.

    We had a similar problem which turned out to be static build up.
    I would check all ares of earth connection.

    If not, do you have the machine at your home base, if so, I know you said that all types of paper are used but does your paper work the best.

    cheap paper can be sold under various brands.

    Approx. how many copies between buildup? This sounds like way too much dust for even bad paper. I would pull one into the shop remove covers, drum, dv ect. hit it with the air hose and see what comes out. Then check operations with covers off, make sure all fans are working.

    This is totally uncharacteristic for a Tiger, even with the worst paper.

    ATSBMCO has a good idea. Make sure that you don't have a significant ground to neutral AC voltage. I would imagine that you're ground would have to be completely absent to accumulate that much static buildup.
