    If that page was SEF (short edge feed), I'm going to guess that you've got an obstruction under the doctor blade, leaving a blank band on the developing roller. =^..^=
    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.

    Is the strip completely blank? Does it always appear in the same place?
    If so, it is possible that something is clogging the developer roller or that the laser glass is dirty

    Both mentioned already. Pls try harder.

    Re: [Need Help] empty lines on printed document

    The picture you shared is REALLY small, so it's hard to make a proper determination. Like others have suggested, I'm leaning towards junk caught in the dr blade leaving those void areas. It's very common on these for dust and junk to get caught in the blade because this model recycles the "waste" toner.

    One other thing that I have seen happen on these is the foam strip attached to the erase lamps starts to breakdown because of the age. I've had at least 2 occurrences where a small piece of that foam was hanging down from the erase lamp board and blocking the laser path. It took me quite a while to find that issue, because it's not easily seen unless you think to bend over a bit more and look up.

    In these models, Drum and Developer both can make this problem.

    I had that once on a 250. I found the fault quite easy as the hanging foam strip was quite obvious standing in the way of 'the beam'
