    Lol agreed, it could be the problem for real.
    Recently have similar problem on C227, few void white lines on black, replaced another drum, checked developing unit, lines still there.
    When i remove laser i found dead-melted spider on laser glass for black

    Either one of these are likely possibilities. Based on your samples, I'm leaning towards the first one. Either a toner rock or some other foreign contaminant collected under the doctor blade will account for this. Small contaminants tend to wedge in, under the doctor blade, so they stay still. Larger contaminants can float around and show up in different places on the image. =^..^=
    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.

    So i have done this and test again, i printed 3 pages which was very good, then same problem appears with little difference, which are that the wrriting is there on paper but not very black, to see the examples here is the links :

    FG-1 — ImgBB
    FG-2 — ImgBB


    reminder : paper format is A4 and the orientation is landscape

    All of us here started guessing from deep possible problem but did you check fuser roller and drum for damage in the middle section?
