I think it was on this model, but not exactly sure. Remove laser unit, (left side of machine --> remove two screws to drop down that cover --> remove waste toner #2/ cleaning unit --> remove the two fans/brackets --> disconnect some harnesses --> remove laser unit (two screws), check to see that the shutter on the laser unit isn't bound up or has loose screw). I think there are some SP's you can adjust also, just can't remember which ones right now (will update if I find them).

As far as i know, there is no laser shutter on this model

did you check that lever that locks the black drum and brings the ITB closer to drum?
I had this and it gave me an undertoned copy/print.
It would lock over but it didnt go correctly. took it apart and played with it

If the calibrations ACC printout sheets looks normal, i would also check user tools - > scanner and copy/document server settings. Check and set the parameters to default. Do a scan with a color/bw test chart to the document server and have a look to the preview if it's ok or not.
