I Some parts inside the machine are subject to high-voltages and
temperatures. Take adequate precautions when inspecting the inside of the
machine. Do not carry out any inspections not described in this manual.
I Be careful not to drop any foreign objects, such as paper clips or staples,
inside the machine. If a foreign object comes into contact with electrical
parts inside the machine, it may cause a short circuit and result in a fire or
1
electrical shock.
I If there is smoke, or unusual noise, immediately turn the main power
switch OFF, disconnect the power cord from the outlet, and contact your
service representative. Using the machine in this state may cause a fire or
electrical shock. Also, avoid placing objects around the power plug so that
the machine can be unplugged whenever necessary.
I Do not turn the main power switch OFF or open the front covers while the
machine is in operation. This may result in paper jams.
I Do not use flammable sprays, such as spray glue, near the machine. There
is a danger of ignition.
