Important
• 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.
• Handle the toner cartridge carefully. If
toner scatters on your hands or clothes,
wipe or wash it off with cold water at once.
• To prevent damage to the machine
caused by static electricity, DO NOT touch
the electrodes shown in the illustration.
