•   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. 

•   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.
