the LED array is likely dirty.

I have been having similar issues. Any one else have anything to add?

the LED array is likely dirty.

More likely some a foreign contaminant causing distortion in that case.

If it was toner the image would be lighter in those areas.
Giving every thing in that engine a good cleaning does magic.

How does the mag roller look any scratches or build-ups?

Like the others have said: between the LED array and the charge grid, that pretty much resolves all quality issues. Do you have a sample of 15% halftone fill? That would tell a lot more. =^..^=

Wanted to say that I had this problem a while back and It would come and go. I came to the conclusion that it was a combo of environment(higher humidity) and usage pattern(or lack there of). I checked all of that stuff, charge and LED etc. Ended up being just running a stabilizer in the morning would resolve it.
