The idea is to try to identify patterns in the half tone. Patterns like you might identify from:
A charge problem, like voids in the feed direction
A re-occurring defect, like from a roller
A drum ground problem, like voids or bars crossfeed
or a focus problem, like the background fading out toward one side or another.

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.

Well, I couldn't find any orange paper, but I took a full page high quality photo with me that was mostly dark yellow.
Did several sky shots that all had the same 1 1/2 inch void/light area on it, at the same spot every time, and always from the top of the machine. The photo showed the same results.
I took several items with me to troubleshoot (Process unit, transfer roller assembly....etc) and nothing seemed to get rid of the problem. I am still leaning towards the LSU, but open to suggestions.
THANKS
As suggested, LSU issue or optics are out of alignment.
Cthulhu for president! Why settle for the lesser evil?
I am hoping for the first (oddly enough) because I know nothing about optic alignment. At least I have replaced an LSU before.
Thanks for the help.
I appreciate it.
The manuals just make it seem harder than it really is, it's more tedious than anything. Nothing really to worry about... Starting with the laser first would be a simpler option however.

Kinda silly on my part, something I just completely forgot about because it just doesn't happen to me in the field.
The problem was SO SIMPLE. The fix..... clean the "glass" on the under side of the LSU. UGH
This one got me. Maybe it will help someone else in the future. ha
Good catch. If you get around to changing one of these lasers keep in mind that the alignment pins in the frame fit very tightly into the laser housing. So remove the mounting screws and carefully lift all four corners just a little to make sure that the laser is free of the pins. On my first one I lifted just at the front, and broke off the two rear alignment pins. It's not catastrophic ... just not the best way to do it. =^..^=
