# Maintenance and Inspections

WARNING
When cleaning the printer, turn OFF the printer and computer, remove the interface cables, and then unplug the 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 printer with a well wrung out cloth dampened with water or mild detergent diluted with water. Do not use alcohol, benzine, paint thinner, or other flammable substances. If flammable substances come into contact with electrical parts inside the printer, this may result in a fire or electrical shock. Some areas inside the printer are subject to high voltage. When removing jammed paper or when inspecting the inside of the printer, be careful not to allow necklaces, bracelets, or other metal objects to touch the inside of the printer, 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. If you accidentally spill or scatter toner, carefully gather the toner particles together or wipe them up with a soft, damp cloth in a way that prevents inhalation. Never use a vacuum cleaner that does not have safeguards against dust explosions to clean up spilled toner. Doing so may cause a malfunction in the vacuum cleaner, or result in a dust explosion due to static discharge. Confirm that the power plug or power connecter is inserted completely after cleaning the printer. 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 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, plug, and connector are not handled in the following manner. This may result in a fire or electrical shock. The power connector is loosened. The power plug is loosened. Stress is being applied to the power cord by a heavy object or by fixing it with staples. 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
Never attempt to service this printer yourself, except as explained in this manual. There are no user serviceable parts inside the printer. Adjust only those controls that are covered in the operating instructions. Improper adjustment could result in personal injury and/or damage requiring extensive repair that may not be covered under your Limited Warranty. The fixing unit and its surroundings inside the printer become hot during use. When removing jammed paper or when inspecting the inside of the printer, 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 printer according to the displayed message. Also, do not put your hands forcibly in the parts other than those directed on the screen. Failure to do so may result in burns or injuries. 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 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.
