Maintenance and Inspections
WARNING
• When cleaning the printer, turn OFF the printer and computer, remove the USB cable,
and then unplug the power plug. Failure to observe these steps may result in a fire or
electrical shock.
• 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.
• Clean the printer using a slightly dampened cloth with water or a 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 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 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.
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.
