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 cartridge to ignite, resulting in burns or a fire.
CAUTION
The toner fixing unit and its surroundings inside the machine may become hot during
use. When removing jammed paper or when inspecting the inside of the machine, do
not touch the toner 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 them with warm water will set the toner, and make it impossible to remove
the toner stains.
When removing paper which has become jammed inside the machine, remove the
jammed paper gently to prevent the toner on the paper from scattering and getting
into your eyes or mouth. If the toner gets into your eyes or mouth, wash them
immediately with cold water and immediately consult a physician.
When loading paper or removing jammed documents or paper, take care not to cut
your hands on the edges of the documents or paper.
When removing a used toner cartridge from the machine, remove the cartridge
carefully to prevent the toner from scattering and getting into your eyes or mouth. If
the toner gets into your eyes or mouth, wash them immediately with cold water and
immediately consult a physician.
