    Both tricks seems to work.

    Then some machines have it and others don't. May be its how those parts come together.
    Squaring up the hinges, look for bent stuff.

    That is really a good idea, but can you please tell me that if i cut that spring and lower the tension of transfer roller then why that spring is there? Did the Engineer of Designer/manufacturer was fool to put that spring there? The spring is just to provide tension so that paper touch the drum firmly and equal and even print transfer is done.

    Actually there is no need for developing unit spacers to touch drum at worn area.
    Magnetic brush will do this damage due to rear distance to drum is narrowed.
    Do they use OEM toner? If not that may be the reason.
    Never argue with an idiot. They will drag you down to their level and beat you with experience.

    Can't there be an obstacle in the drum's revolution before paper passes. A raised area or an object along the pathway of the drum's turning can as well cause this problem. Check any such probable obstacle.

    The usual problem is that the rear developer unit spacer wears down causing the space between the developer brush and drum surface to be reduced enough that the developer brush starts to wear down the drum coating until it begins to flake off the drum surface.

    They are using OEM toner, if not then how can using counterfeit toner affect drum from this side?
    I agree magnetic brush can damage due to narrowed distance.

    I have checked it.There is no such thing in the passage of paper. They are using paper in long edge (lengthwise).

    clearly by your questions:
    you are a newbie
    -=or=-
    you never worry about how things work... and just "go by the book"

    go to your service manager demand he give you access to the sites you need.. if he refuses then you have two options Quit ot go above his head and complain to Owner. if you don't get issue resolved quit.

    This is very common on these machines. Those units will not last their life without the spacers with the bearing in them. You have the answers to the problem.

    I totally agree with you and tsbservice in this regard. The worn spacer at the rear end is the reason. Why this spacer is worn out before time? The life of DV Tank is 590K? The spacer rotation is stiff? or it is just because that rear side is close to Gears assembly?

    I will replace the DV tank or spacer somehow but i also want to fix the problem which is creating this mess. Damaging or wearing of Spacer. ???

    I am a nerd as you can see. Thank you very much for helping me to resolve the issue. I will say i go by the book most of the time. I agree.
