you have to clean the mirror in image scanner and also the disk inside the image scanner. use cotton buds for cleaning

Perform manual calibration.
If problem persists do a jam test.
If jam test shows complete image on drums, then check transfer mechanism is sufficiently pressurized.
If jam test shows incomplete image on drums, then check drum unit, and charge supply. Also check output for CTD report.
