Maintenance and Inspections
WARNING
•
When cleaning the machine, first turn OFF the main power switch, then disconnect
the power cord. Failure to observe these steps may result in a fire or electrical shock.
•
Disconnect the power cord from the power outlet regularly, and clean the area around
the base of the power plug’s metal pins and the power outlet with a dry cloth to
ensure that all dust and grime is removed. If the power cord is connected for a long
period of time in a damp, dusty, or smoky location, dust can build up around the
power plug and become damp. This may cause a short circuit and result in a fire.
•
Clean the machine using a slightly dampened cloth with a mild detergent mixed with
water. Do not use alcohol, benzene, paint thinner, or other flammable substances.
Check detergent for flammability prior to use. If flammable substances come into
contact with a high-voltage area inside the machine, it may result in a fire or electrical
shock.
•
There are some areas inside the machine which are subject to high-voltages. When
removing jammed paper or when inspecting the inside the machine, do not allow
necklaces, bracelets, or other metal objects to touch the inside the machine, as this
may result in burns or electrical shock.
•
Do not burn or throw used toner cartridges into open flames, as this may cause the
toner remaining inside the cartridges to ignite, resulting in burns or a 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.
•
Make sure that the power plug is firmly inserted into the power outlet after cleaning
the machine. Do not use the machine while the connection is loose, as doing so may
cause a fire.
•
Check the power cord and power plug regularly. If the following conditions occur,
contact your local authorized Canon dealer, as the condition may cause a fire:
- There are burn marks on the power plug.
- The blade on the power plug is deformed or broken.
- The power goes OFF and ON when the power cord is bent.
- There are cuts, cracks, or indentations on the power cord.
- A part of the power cord becomes hot.
•
Check the power cord and power plug regularly to make sure that they are not
handled in the following manner, as this may result in a fire or electrical shock:
- The connection part of the power plug is loose.
- Stress is being applied to the power cord by a heavy object or by affixing it with
staples.
- The power plug is loose.
- The power cord is tied in a bundle.
- The power cord protrudes into a walkway.
- The power cord is in front of a heater.
