check drum or drum sleeve..
Check the maylar, it may scrape developer in the developing unit.

Clean color registration sensor..

4520 points hand in color registration sensor.

Color registration error appears that because cyan it is not written properly on the belt. The issue is why it is not written properly. Check the drum if the image is ok and then check the belt, if the image is transferred properly.
