    I've looked and I can't really find a solution to this, I'm working with 80# Satin Cover, basically the front side comes out looking beautifully but the back side has weird artifacts going right through the middle. I've run about 25 sheets and it's the same thing for every sheet, the front side looks good and the back side looks bad. The only thing I changed was the fuser roll because the other got chewed up, but I checked the contact arc and it is correct. I have attached a picture of what the back side looks like, it goes from lead edge to tail edge.

    Update: This doesn't happen when I run C1S, everything lays down fine on that paper.

    Hi Adam
    verify you have correct gsm in for your stock. Then under the stock your running in subsytem attributes adjust your transfer voltage up or down. Usually its down this time of year due to dry conditions. Hope this helps.
    satin finish is very touchy stuff it is best to have fresh wrapped reams of stock

    The gsm is correct, and upon closer inspection this problem is only occurring in magenta, all of the other colors lay down fine. I've also noticed on everything else that magenta will start to drift after only 10 prints and stays that way, the first few prints always show up perfectly fine. I have run multiple xerographic and ioi setups and have made sure etac timing was good and still hasn't fixed the issue. I have actually stopped running the satin paper because I can't figure out what the problem is, but now with this magenta drifting issue I am having to stop and start the prints way too often or else they start looking bad.

    Replace the center etac. Classic running along and all of a sudden no mag cycle down restart mag comes back. Also if you have not redone mag developer in a while this will also help. Color drift is no fun

    Just to clear it ONLY occurs with the one media, and only on the back? Try and 80# gloss cover, or perhaps any other 80# coated you might have?
    Although with the addition of the magenta color drifting all around, seems like the issue lies within that imaging unit itself. I can't really put my finger on why only the back. Perhaps it's unable to maintain charge or voltage levels for duplex (or at all, if the color is drifting).

    I'm curious what the defect might look like on a sheet of low density magenta, duplexed. 20% or so.

    Magenta developing station or drum due for service?
