I have a 4540 with some cyan shading. Printing is fine. Laying original on the glass is fine. Only does it through the document feeder. Cyan drum and developer were due to be changed so I changed them. Cleaned mirrors and lens. The shading occurs in the same spot with the same pattern. Sample attached. My sample upload keeps failing.

Re: 4540C cyan shading
Sample?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: 4540C cyan shading
Feed direction is denoted by the arrow half way down. Letter paper, long edge feed. Haven't run those test patterns as printing is fine. It only occurs through the ADF on full or auto color, not BW.
Did you want the test prints run through the ADF?Comment

Re: 4540C cyan shading
Sounds like sound plan.
the reason I asked for prints is that it's very rare to get an ADF Only image quality issue. Odds are when you look at these prints you'll see the same issue that you hadn't noticed before on other less telling images.

Re: 4540C cyan shading
ADF height can be causing this issue if you're sure it's only happening through the ADF.Comment

Re: 4540C cyan shading
There is a background adjustment for scanning that can be performed to remove this background. It is in the Service Manual and Handbook.Comment
