• Do not use power cords other than the one provided, as this
can result in a fi re or electrical shock.
• As a general rule, do not use extension cords. Using an ex-
tension cord may result in a fi re or electrical shock.
• Remove the power plug from the AC power outlet and
refrain from using the machine while it thunders. Lightening
can result in a fi re, electrical shock or malfunction.
CAUTION
• Do not use a power supply voltage other than that listed
herein, as this may result in a fi re or electrical shock.
• Always grasp the power plug when unplugging the power
plug. Do not pull on the power cord, as this may expose the
core wire of the power cord or damage the cord insulation,
causing electricity to leak, resulting in a fi re or electrical
shock.
• Leave suffi cient space around the power plug so that it can
be unplugged easily. If objects are placed around the power
plug, you may be unable to unplug it in an emergency.
Handling
WARNING
• Do not disassemble or modify the machine. There are
high-temperature and high-voltage components inside the
machine which may result in a fi re or electrical shock.
• Electrical equipment can be hazardous if not used properly.
Do not allow children to touch the power cord, cables, inter-
nal gears, or electrical parts.
• If the machine makes an unusual noise or emits smoke,
heat, or an unusual smell, immediately turn off the power
switches of the machine and computer and disconnect the
interface cable if it is connected. Then, unplug the power
plug from the AC power outlet and contact your local au-
thorized Canon dealer. Continued use can result in a fi re or
electrical shock.
• Do not use fl ammable sprays near the machine. If fl ammable
substances come into contact with electrical parts inside the
machine, this may result in a fi re or electrical shock.
• Always turn off the power switches of the machine and com-
puter, and then unplug the power plug and interface cables
before moving the machine. Failure to do so can damage
the cables or cords, resulting in a fi re or electrical shock.
• Confi rm that the power plug or power connecter is inserted
completely after moving the machine. Failure to do so can
result in an overheating and fi re.
• Do not drop paper clips, staples, or other metal objects
inside the machine. Also, do not spill water, liquids, or other
fl ammable substances (alcohol, benzene, paint thinner, etc.)
inside the machine. If these items come into contact with
a high-voltage area inside the machine, this may result in a
fi re or electrical shock. If these items are dropped or spilled
inside the machine, immediately turn off the power switches
of the machine and computer and disconnect the interface
cable if it is connected. Then, unplug the power plug from
the AC power outlet and contact your local authorized
Canon dealer.
• When plugging or unplugging a USB cable when the power
plug is plugged into an AC power outlet, do not touch the
metal part of the connector, as this can result in electrical
shock.

CAUTION
• Do not place heavy objects on the machine. The object or
the machine may fall, resulting in personal injury.
• Turn off the power switch when the machine will not be
used for a long period of time, such as overnight. Turn off
the machine and unplug the power plug if the machine
will not be used for an extended period of time, such as for
several days.
• Open or close covers and install or remove cassettes gently
and carefully. Be careful not to hurt your fi ngers.
• Keep your hands and clothing away from the roller in the
output area. Even if the machine is not printing, the roller
may suddenly rotate and catch your hands or clothing,
resulting in personal injury.
• The output slot is hot during and immediately after printing.
Do not touch the area surrounding the output slot, as this
may result in burns.
• Printed paper may be hot immediately after being output.
Be careful when removing the paper and aligning the re-
moved paper, especially after continuous printing. Failure to
do so may result in burns.
• When performing copy with a thick book placed on the
platen glass, do not press the feeder forcefully. This may
damage the platen glass and cause personal injury.
• Be careful not to drop a heavy object, such as a dictionary,
on the platen glass. This may damage the platen glass and
cause personal injury.
• Close the feeder gently so as not to catch your hand. This
may result in personal injury.
• The laser beam can be harmful to human bodies. The laser
beam is confi ned in the laser scanner unit by a cover, so
there is no danger of the laser beam escaping during normal
machine operation. Read the following remarks and instruc-
tions for safety.
- Never open covers other than those indicated in this
manual.
- Do not remove the caution label attached to the cover of
the laser scanner unit.
- If the laser beam should escape and enter your eyes, expo-
sure may cause damage to your eyes.
• If you operate this machine in manners other than the
control, adjustment, and operating procedures prescribed in
this manual, this may result in hazardous radiation exposure.
