Maintenance and Inspections
WARNING
• When cleaning the printer, first turn OFF the power switch, disconnect the USB cable,
then unplug the power plug. Failure to observe these steps may result in a fire or
electrical shock.
• Clean the printer 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 printer, it may result in a fire or electrical
shock.
• There are some areas inside the printer which are subject to high-voltages. When
removing jammed paper or when inspecting the inside of the printer, do not allow
necklaces, bracelets, or other metal objects to touch the inside of the printer, as this
may result in burns or electrical shock.
• Do not burn or throw a used toner cartridge into open flames, as this may cause the
toner remaining inside the cartridge to ignite, resulting in burns or a fire.
• Unplug the power plug from the AC power outlet regularly, and clean the area around
the base of the power plug's metal pins and the AC power outlet with a dry cloth to
ensure that all dust and grime is removed. If the power plug is plugged 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.
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 may 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 doing so may result in burns or
electrical shock.
• When removing jammed paper or replacing the toner cartridge, take care not to allow
the toner to come into contact with your hands or clothing, as this will dirty your
hands or clothing. If they become dirty, wash them immediately with cold water.
Washing with warm water will set the toner and make it impossible to remove the
toner stains.
