A. WARNING
1) Never use a power source of more than 15A, 100V.
Avoid complex wiring, which may lead to a fire or an electric
shock.

2) When any abnormality occurs, such as smoke or bad smell, do not
use the machine. If used in abnormal conditions, a fire or an
electric shock may be resulted.

3) Be sure to connect the grounding wire. If an electric leakage oc-
curs without grounding, a fire or an electric shock may be resulted.
To protect the machine and the power unit from lightening,
grounding must be made.
To protect the machine and the power unit from lightening,
grounding must be made.
4) When removing the cabinet of the machine, use an extreme care.
There is a high voltage section inside the machine which may
cause an electric shock when touched. Do not leave the machine
with the cabinet removed. It is very dangerous for the user to
touch the inside of the machine.

touch the inside of the machine.
5) Do not damage, brake, or work the power cord. Do not put a
heavy thing on the power cord. Do not pull or bend the power cord
extremely. Otherwise, the power cord may be damaged to cause
a fire or an electric shock.

7) If water or a metal piece drops into the machine, turn off the power
switch, disconnect the power plug, then remove the dropped thing.
8) Do not use a wet hand to disconnect or insert the power plug and
to operate or service the machine. It may cause an electric shock.
B. CAUTION
1) Avoid installation on an unstable surface or a slant surface. Other-
wise, it may drop from the surface, resulting in an injury. It is ad-
visable to use the optional paper feed desk or the exclusive-use
desk.

desk.
2) Avoid installation in a humid or dusty place. Otherwise, a fire or an
elctric shock may be resulted.
3) The fusing section is very high. Be careful not to burn when ser-
vicing.
4) When disconnecting the power plug from the power outlet, do not
pull the power cord. Otherwise, the cord may be damaged, result-
ing in exposed core or disconnection, causing a fire or an electric
shock.

shock.
5) Do not throw toner or a toner cartridge in a fire. Otherwise, toner
may pop and burn you.
6) When using the optional paper feed desk or the exclusive-use
desk, be sure to fix the adjusters on the floor, and lock the casters.
As shown in the figure, rotate the adjuster in the fixing direction
until it makes contact with the floor. Lock the casters to fix the
machine. (If the casters are not locked, the machine may gradually
move so that the SPF cable may be rubbed with the wall, causing
disconnection.

7) Do not see the light source and the laser beams. Otherwise the
eyes may be damaged.

heater switch, and be sure to disconnect the power plug from the
power outlet. If not, the cord may be damaged to cause a fire or
