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.

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.
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.
Growth is found only in adversity.
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.

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.
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.
It’s not a sky shot. Is it a copy of an original off the glass with the document feeder open ?
What are the internal prints like?
..and for best clarity, we always recommend our clients send in pictures of the image they want us to fault find rather than scans as scans introduce their own issues!
Internal print.
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 ...). =^..^=
