Konica Miolta C452 Copy Quality issue.

Please find the attached image as on the one side 20% bottom of the image is blurry and getting one horizontal white line. This page is A3.
Replaced IUs and transfer belt. But no improvement.

Please advise.

Thanks and Regards,

print all 4 halftone or gradation test patterns from service mode to see if all colors affected, looks to me like dirt on either the laser slit glass or a dirty corona (of cyan is my guess)
