If you've just used the machine, its internal parts will be extremely hot. Wait for the machine to cool down before touching any
internal parts.
3. Remove the drum unit and toner cartridge assembly for the color you're replacing (the color that needs to be replaced will be

We recommend placing the drum and toner assembly on a clean, flat surface with disposable paper underneath it in case you
accidentally spill or scatter toner.
4. Push down the green lock lever and remove the toner cartridge from the drum unit.
