        Problem on both Black and Color copies?
        Possible faulty Print Head Unit, as a test, the print heads can be swapped.

              printhead=laser=write unit
              same thing
              We know a thing or two because we've seen a thing or two.
              The medication helps though...

                a colleague who repairs Konica Minolta suggests that I revise the grids of perhaps oxidized photoconductor units. I'll start from here. Then I will think of the "printhead" unit.

                  Also check the harness between the Laser Unit and MFP Board, sometimes it's bad connection. Good Luck!
