    Hi
    I replaced the K laser unit, no change , than swapped the entire laser assembly (frame with lasers), no change. AND tried a new fuser, no change....What you are saying about the skewed image on the transfer belt is bugging me the most and I think is the key to the problem, that's why I tried the K laser than the entire assy.

    Thanks

    just wondering what its like if you do single colour cyan or magenta will it be skewed as there are 4 individual lasers just wondering now if someone has maybe been playing with the allen screws on the front of the laser accessible behind drum and dev unit cover as if my memory serves me right adjusts the angles of the laser mirrors. if skewed on transfer it can only be laser unless the belt is wandering off somehow, hope this helps

    It's on all colors, that's why I swapped the entire laser assy with a known good on. I was told be tech support that the K laser image is used as a reference point for all the colors and image. That's why at first I replaced the K laser.

    Thanks

    Re: *&%&%& 3050ci with skewed image.. HELP

    Is the machine sitting on level ground/floor eg. uneven tiles ?

    Has the main frame of the machine been twisted updown or skewed sideways during transport?
    Has the entire machine been carelessly lifted/dropped on one corner of the machine ?

    I'm thinking with a bent main frame the rego-rollers might not be sitting exactly linear, and may be moving the copy paper to the front/rear side during conveyancing.

    What if we could count the stars... , what number would you stop at...?"

    Hi
    The floor is level and according to the customer output was normal after installation. Also the copier is sitting on the 3k paper deck.We pulled the copier and gave then the same for a loaner and the loaner is working perfectly. I keep thinking that the image was not completely square to the paper from jump street ,but the customer swears that output was perfect until several months ago..VERY FRUSTRATING...

    Thanks

    You mention it in your initial post but I'm just checking you did Service Bulletin E164-2N4-0025 (which would have changed if you used an entirely different conveying unit).

    Our machine is in a church that really isn't noticing but an autistic child in the daycare brought it to their attention.

    I attached a pic from our Tech Rep from a feed port itself. We found that if you pulled out Trays 1 or 3 and reached in and put finger pressure on trail edge front or rear of the paper you could mess with the "skew" on legal and ledger which is the most noticeable. I haven't been back to "bend" the metal, we messed around with different springs from our "bag o' springs" cause the little one's that are in there are weak little pieces of crap.

    Hope this helps. Good times making big changes and getting the same results
