Cleaning the drum unit

We recommend placing the drum unit and toner cartridge assembly on a cloth or large disposable paper to avoid spilling and scattering toner.

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

2 Return the blue tab and snap it into the Home position (▼).
