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

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!
