– Never open covers other than those instructed in this manual.
– Do not remove the caution label attached to the fixing unit and the duplex unit.
– When cleaning the machine, first turn off the main power switch, and 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 area inside the machine which are subject to high‑voltage. 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 cartridges into open flames, as this may cause the toner
remaining inside the cartridges to ignite, resulting in burns or a fire.
