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.

CAUTION

• The fixing unit and its surroundings inside the machine

become hot during use. When removing jammed paper or

when inspecting the inside of the machine, do not touch

the fixing unit and its surroundings, as this may result in

burns.

• When removing jammed paper or when inspecting the

inside of the machine, do not expose yourself to the heat

emitted from the fixing unit and its surroundings for a

prolonged period of time. Doing so may result in low

temperature burns, even though you did not touch the

fixing unit and its surroundings directly, as this may result

in burns.

• If paper is jammed, remove the jammed paper so that

any pieces of paper do not remain inside the machine

according to the displayed message. Also, do not put your

hand in an area other than indicated areas, as this may

result in personal injuries or burns.

• When removing jammed paper or replacing a toner

cartridge, be careful not to get any toner on your hands or

clothing, as this will dirty your hands or clothing. If toner

gets on your hands or clothing, wash them immediately

with cold water. Washing with warm water sets the toner,

making it impossible to remove the toner stains.

• When removing jammed paper, be careful not to allow the

toner on the paper to scatter. The toner may get into your

eyes or mouth. If toner gets into your eyes or mouth, wash

them immediately with cold water and consult a physician.

• When loading paper or removing jammed documents or

paper, be careful not to cut your hands with the edges of

the paper.

• When removing a toner cartridge, remove the toner

cartridge carefully so as to prevent the toner from

scattering and getting into your eyes or mouth. If toner gets

into your eyes or mouth, wash them immediately with cold

water and consult a physician.

• Do not attempt to disassemble the toner cartridge. The

toner may scatter and get into your eyes or mouth. If toner

gets into your eyes or mouth, wash them immediately with

cold water and consult a physician.

• If toner leaks from the toner cartridge, be careful not to

inhale the toner or allow it to come into direct contact with

your skin. If the toner comes into contact with your skin,

wash with soap. If the skin becomes irritated or you inhale

the toner, consult a physician immediately.
