Itb or fuser cleaning section.

What color are streaks..if brownish,itb cleaning..if specific color,then that drum. You can pull off the right cover(1 screw) and watch copy being developed on itb...if streak on non image area,probably itb cleaning blade..if in image area only,needs drum unit of that color
