IMPORTA NT
We recommend that you place the drum unit and toner cartridge assembly on a clean, flat surface with a
sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner.
To prevent damage to the printer from static electricity, DO NOT touch the electrodes shown in the
illustration.
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.
