Cleaning the Drum Unit

We recommend you place the drum unit on a drop cloth or large piece of disposable paper to avoid spilling and scattering toner.

1 Clean the primary corona wire inside the drum unit by gently sliding the tab from right to left several times.

2 Return the tab to the home position (mark position) before reinstalling the drum unit.
