Maintenance And Inspections - Canon imageRUNNER ADVANCE C2020L Handbuch

• The laser beam can be harmful to human bodies. Since radiation emitted inside the product is completely
confined within protective housings and external covers, the laser beam cannot escape from the machine
during any phase of user operation. Read the following remarks and instructions for safety.
• Never open covers other than those instructed in the manuals for this machine.
• Do not remove the following caution label which is attached to the machine. If the label has been removed, contact your local authorized
Canon dealer.
• If the laser beam escapes from the machine, exposure may cause serious damage to your eyes.
• Controlling, adjusting, or operating the machine in ways not mentioned in the manuals for this machine may cause dangerous radiation
to escape from the machine.
IMPORTANT
Turn OFF the control panel power switch for safety when the machine will not be used for a long period of time, such as
overnight. Also, turn OFF the main power switch, and disconnect the power cord for safety when the machine will not be
used for an extended period of time, such as during consecutive holidays.

Maintenance and Inspections

• 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 of the machine, do not allow necklaces, bracelets, or other metal objects to
touch the inside of 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.
• 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.
