Maintenance and Inspections

WARNING
When cleaning the machine, first turn OFF the main power switch, then unplug the
power plug. Failure to observe these steps may result in a fire or electrical shock.
Unplug the power plug from the outlet regularly, and clean the area around the base
of the plug's metal pins and the power outlet with a dry cloth to ensure all dust and
grime is removed. If the machine is plugged in for a long time in a damp, dusty, or
fumy location, dust can build up around the plug and become damp. This may cause
a short circuit and result in a fire.
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 throw used toner cartridges into open fires. The toner will catch on fire and
may cause burns or fire.
