Important Safety Instructions
Confirm that the power plug or power connecter 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.
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 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 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.
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.
Maintenance and Inspections
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.
