• When installing the cleaning blade assy, be sure to apply setting powder to the circumference of
the drum and the cleaning blade, regardless of these parts being new or used ones.
• When setting powder is applied to the drum, be sure to conduct the following operations before
installing the drum unit to the main body.
1) With the charging corona unit removed, rotate the drum 1 full turn (to prevent setting powder
