a Turn off the machine. Unplug the
telephone line cord first, disconnect all
cables, and then unplug the power cord
from the electrical socket.

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.

caused by static electricity, DO NOT touch
