CAUTION
We recommend that you place the toner cartridge on a clean, flat surface with a piece of disposable paper
underneath it in case you accidentally spill or scatter toner.
DO NOT put a toner cartridge into a fire. It could explode, resulting in injuries.
Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold
water at once.
To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations.
