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.
