IMPORTANT
• Hold the green handles of the drum unit
when you carry it. DO NOT hold the sides
of the drum unit.
• We recommend that you place the drum
unit on a clean, flat surface with a piece of
disposable paper underneath it in case
you accidentally spill or scatter toner.
• Handle the toner cartridge and the waste
toner box 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 from
static electricity, DO NOT touch the
electrodes shown in the illustration.
