• If you attempt to operate this machine with the top cover opened
and the top cover interlock safety switch bypassed, there is dan-
ger of laser radiation, and of your clothes or fingers becoming
caught in the drive gears and rollers, and of coming into contact
with the heated surfaces of the Fuser. You should never attempt to
operate this machine with the top cover safety interlock bypassed.
• When replacing parts, be sure to turn the power switch OFF and
unplug the AC power cord from the outlet.
• Be sure to output a dial list and a system function list and keep
them until the trouble analysis is completed so that if the user's
set data is lost it can be re-entered.
• Before turning the power switch OFF, be sure to confirm that the
residual memory is 100% and no memory reception documents
exist. If there is such a document, it will be lost if the service activ-
ity requires the battery backup to be unplugged.
• Cover the Drum unit with a cloth, and so on, whenever it is re-
moved from the machine to protect the photosensitive material
from deterioration by exposure to light.
