    No it has not.
    How is that removed, through the front or from the left side?
    I am going back with a new developer unit today so I can look at that part as well.

    I think he's referring to the dust catch that snaps in. They're usually red in color. That whole area/cavity should be vacuumed out.

    Replaced developer unit and cleaned dust collector still have line.
    Is it possible for laser to cause this?

    Laser? Unlikely.

    I think I would very closely examine the area around the drum for fibers dangling onto the drum surface. I've found fibers stuck to the grid, statically attracted to the drum blade, or stuck to the upper developer seal ... really anywhere within reach of the drum. These fibers can be very very fine, and nearly impossible to see.

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

    5050 paper path is simple as they come. With a clean machine and new OEM parts and supplies there cannot be this defect. Are you on site or one of your techs? Something doesn't add up.

    Maybe the paper has defects from factory?

    It is me and I agree it doesn’t add up.
    sounds like a good idea to check the paper at this point.
    Here is one more sample and notice none of them are on the same line or position
