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. =^..^=

Dirty laser glass? Try the magic wand.

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

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'

The page is A5 Format, and i think it's what you refer as SEF, you can see this picture

i dont think that the laser glass is dirty because scaning to pc gives good image, and printing from pc gives the same problem, so it's not the scaning laser glass problem

thanks for the idea

i tried scaning to computer it gives good image
i tried printing from computer it gives the same problem on printed document,

i think it can be the drum unit that must be changed.
