■ If there is smoke, or unusual noise, immediately turn the main power
switch OFF, disconnect the power cord from the outlet, and call your local
authorized Canon dealer. 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 disconnected whenever necessary.
■ Do not turn the main power switch OFF or open the front covers while the
machine is in operation. This might result in paper jams.
■ Do not use flammable sprays, such as spray glue, near the machine. There
is a danger of ignition.
