Attached is a sky shot from this machine. I tried DV unit, drum, belt, and high voltage pwb. Any one seen this?

Re: 4002i
Did ya deep clean the optics?
Did ya run U061 with the lid up and see if the light was uneven?
Did ya check and clean the white balance under the glass?
I know these are simple things, but they got me once or twice. -
Re: 4002i
For clarity: I refer to a "sky shot" as a copy made with the ADF/Platen open and nothing on the glass. Is the first page of your samples an internal print or a copy of an internal print?
Your Send Result page looks clear except for the area that was scanned during the fax process. This indicates the print engine (drum, dev, belt, transfer) are all ok and the problem lies in the scan section which points back to the recommendations by Samantor.Comment

Re: 4002i
darryl and samanator have covered the things that you need to check. In the future, you should use the process of elimination to determine if the problem lies on the scan or print side. In fact, there's a section in your service manual that explains it in detail.
In this instance, it looks like the problem is in scan section. Refer to the troubleshooting steps given by samanator and/or your service manual.Adversity temporarily visits a strong man but stays with the weak for a lifetime.Comment

Re: 4002i
Another thing to keep in mind is the scan resolution that you have selected for your scan. It may seem obvious, but a low resolution scan of ANY image will look pretty bad.
To narrow down your issue, try scanning an original without the gray background. =^..^=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.

Re: 4002i
Its not optics because internal prints have the same defect. I just did a sky shot to exaggerate the issue. U412 and 410 prints both have the image problem and wont run.Comment

Re: 4002i
Is there a chance you could post a photograph if internal prints as opposed to scans?
With that being a scan its harder to give an opinion.
It looks too much like a DP scan position problem (from the scanner motor being too tight and DP shading position needing adjusting).
If you didn't tell me it was an internal print I would swear it was that.
A photo or two may help us out.
Thanks.Comment

Re: 4002i
You say that developing unit is new? It looks like the same effect you'd see on a Saturn or Alphard with cracked developer spacers: developer bias arcing to the drum surface (lighter oval shapes ...). =^..^=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.

Re: 4002i
It does look like developer leakage (electrical). Try running U140 AC Calib.Comment

Re: 4002i
Yes I did the whole PM kit. Bothe the old and the new DV units do this defect. The pattern just changes a bit when changing between the two. And yes I did run 140 when I installed the PM kit.Comment

Re: 4002i
The last time I saw images like this, I was filling in for another tech. He told me he had installed a developing unit. It turned out to be a used developing unit ... with the same exact issue. =^..^=If you'd like a serious answer to your request:

Re: 4002i
This may not have anything to do with his problem, but I have found if the prints for U410 and U412 and U469 error out, one may need to check that the paper is centered as it comes out of the drawer/cassette.
This can be done with U034 Adjust Paper Timing Data > LSU Out Left > Use the System Menu button to get to the copy screen and pick the cassette to be adjusted. Press Start to print a test page (best to use 8.5x11 paper for this adjustment). Fold the page in half to see what way to change the number for that drawer. Press System Menu button to go back to the adjustment screen and change the value for the desired cassette. Press start to lock it in. Press System Menu button and make another test sheet. Fold the page in half and look for a change. Do this till the center line is in the fold.
I do this to every machine I come across that I have never seen. I do this because it insures print outs for calibrations are properly centered so the machine will read them properly. Too many time I have gone behind other techs that told me they didn't do the calibrations because "the machine gave a funny error when it scanned the sheet. So I blew it off". I would go back, center the page and the machine would read the pages just fine.
