• If excessive stress is applied to the connection part of the power cord, it may
damage the power cord or the wires inside the machine may disconnect. This
could result in a fire. Avoid the following situations:
- Connecting and disconnecting the power cord frequently.
- Tripping over the power cord.
- The power cord is bent near the connection part, and continuous stress is
being applied to the power outlet or the connection part.
- Applying a shock to the power connector.
• Do not use power cords other than the one provided, as this can result in a fire or
electrical shock.
• As a general rule, do not use extension cords. Using an extension cord may result
in a fire or electrical shock.
• Remove the power plug from the AC power outlet and refrain from using the
machine during a thunder storm. Lightning can result in a fire, electrical shock or
malfunction.
CAUTION
• Do not use a power supply voltage other than that listed herein, as this may result
in a fire 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 fire or electrical shock.
• Leave sufficient 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 fire or electrical
shock.
• Electrical equipment can be hazardous if not used properly. Do not allow children
to touch the power cord, cables, internal 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 authorized Canon dealer.
Continued use can result in a fire or electrical shock.
• Do not use flammable sprays near the machine. If flammable substances come
into contact with electrical parts inside the machine, this may result in a fire or
electrical shock.
• Always turn off the power switches of the machine and computer, 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 fire or electrical shock.
• Confirm that the power plug or power connector is inserted completely after
moving the machine. Failure to do so can result in an overheating and fire.
• Do not drop paper clips, staples, or other metal objects inside the machine. Also,
do not spill water, liquids, or other flammable 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 fire 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 fingers.
• 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 removed 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 or the platen glass cover 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 or the platen glass cover gently so as not to catch your hand. This
may result in personal injury.
• The laser beam can be harmful to the human body. The laser beam is confined 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 instructions
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, exposure may cause
damage to your eyes.

Maintenance and Inspections

WARNING
• When cleaning the machine, turn off the machine and computer, and unplug the
interface cables and power plug. Failure to do so can result in a fire or electrical
shock.
• Unplug the power plug from the AC power outlet periodically and clean the area
around the base of the power plug's metal pins and the AC power outlet with a
dry cloth to remove all dust and grime. In damp, dusty, or smoky locations, dust
can build up around the power plug and become damp, which can cause a short
circuit, resulting in a fire.
• Clean the machine with a well wrung out cloth dampened with water or mild
detergent diluted with water. Do not use alcohol, benzene, paint thinner, or other
flammable substances. If flammable substances come into contact with electrical
parts inside the machine, this may result in a fire or electrical shock.
• Some areas inside the machine are subject to high voltage. When removing
jammed paper or when inspecting inside of the machine, be careful not to allow
necklaces, bracelets, or other metal objects to touch the inside of the machine, as
this can result in burns or electrical shock.
• Do not dispose of used toner cartridges in open flames. This may cause the toner
remaining inside the cartridges to ignite, resulting in burns or fire.
• Confirm that the power plug or power connector is inserted completely after
cleaning the machine. Failure to do so can result in an overheating and fire.
• Check the power cord and plug regularly. The following conditions may result in
fire, so please contact your local authorized Canon dealer or the Canon help line.
- There are burn marks on the power plug.
- The blade on the power plug is deformed or broken.
- The power is turned OFF or ON when bending the power cord.
- The coating of the power cord is damaged, cracked, or dented.
- A part of the power cord becomes hot.
• Check regularly that the power cord and plug are not handled in the following
manner. Failure to do so can result in a fire or electrical shock.
- The power connector is loosened.
- Stress is being applied to the power cord by a heavy object or by fixing it with
staples.
- The power plug is loosened.
- The power cord is tied in a bundle.
- A part of the power cord is put in an aisle.
- The power cord is put in front of the heating appliance.
