These sensor windows can get covered in toner and paper dust (See above photo, you can see how typically filthy the inside of this printer can get) The containments on the lens window can cause excessive calibration and print alignment issues.


You can see two of these sensors when you open the right door and remove the transfer belt and if you open the front door and slide the density detect assembly cover towards the rear of the printer, it will expose the other two sensor windows.


Wipe these sensor windows with and towel and maybe some alcohol and see if those calibration issues go away, hopefully that takes care of the issue. This also applies to the CP3525, CP4525, M652/M652 and a bunch of other color lasers.
