Open the top cover.

Remove the drum unit assembly.

Wipe the electric terminals with isopropyl alcohol on a cotton swab.

Wipe the gears with a clean dry cloth.

5 Gently wipe the scanner window and the toner sensor with a clean soft dry cloth. Do not use isopropyl alcohol to clean the scanner window or the toner sensor.

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 Turn the drum unit upside down carefully.

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

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