•We recommend that you place each 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 cartridges carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
