Handling Power Cords and Power Plugs
RWARNING:
• Do not use any power sources other than those that match the
specifications shown. Doing so could result in fire or electric shock.
• Do not use any frequencies other than those that match the specifications
shown. Doing so could result in fire or electric shock.
• Do not use multi-socket adaptors. Doing so could result in fire or electric
shock.
• Do not use extension cords. Doing so could result in fire or electric shock.
• Do not use power cords that are damaged, broken, or modified. Also, do not
use power cords that have been trapped under heavy objects, pulled hard, or
bent severely. Doing so could result in fire or electric shock.
• If the power cord is damaged and its inner wires are exposed or broken,
contact your service representative for a replacement. Use of damaged
power cords could result in fire or electric shock.
Be sure to disconnect the plug from the wall outlet at least once a year and
check for the following:
• There are burn marks on the plug.
• The prongs on the plug are deformed.
If any of the above conditions exist, do not use the plug and consult your
dealer or service representative. Use of the plug could result in fire or electric
shock.
Be sure to disconnect the power cord from the wall outlet at least once a year
and check for the following:
• The power cord’s inner wires are exposed, broken, etc.
• The power cord’s coating has a crack or dent.
• When bending the power cord, the power turns off and on.
• Part of the power cord becomes hot.
• The power cord is damaged.
If any of the above conditions exist, do not use the power cord and consult

• Do not store toner (new or used) or toner containers anywhere near naked
flames. Doing so risks fire and burns. Toner will ignite on contact with naked
flame.
• Do not use a vacuum cleaner to remove spilled toner (including used
toner). Absorbed toner may cause a fire or explosion due to electrical
contact flickering inside the vacuum cleaner.
However, it is possible to use a vacuum cleaner that is explosion-proof and
dust ignition-proof. If toner is spilled on the floor, remove the spilled toner
slowly using a wet cloth, so that the toner is not scattered.
• The following explains the warning messages on the plastic bag used in
this product’s packaging.
• Keep the polythene materials (bags, gloves, etc.) supplied with this
machine away from babies and small children at all times. Suffocation
can result if polythene materials are brought into contact with the
mouth or nose.
RCAUTION:
• Do not crush or squeeze toner containers. Doing so can cause toner spill-
age, possibly resulting in dirtying of skin, clothing, and floor, and accidental
ingestion.
• Store toner (new or used), toner containers, and components that have been
in contact with toner out of reach of children.
• If toner or used toner is inhaled, gargle with plenty of water and move into a
fresh air environment. Consult a doctor if necessary.
• If toner or used toner gets into your eyes, flush immediately with large
amounts of water. Consult a doctor if necessary.
• If toner or used toner is swallowed, dilute by drinking a large amount of
water. Consult a doctor if necessary.
• When removing jammed paper or replacing toner, avoid getting toner (new
or used) on your clothing. If toner comes into contact with your clothing,
wash the stained area with cold water. Hot water will set the toner into the
fabric and make removing the stain impossible.

• When removing jammed paper or replacing toner, avoid getting toner (new
or used) on your skin. If toner comes into contact with your skin, wash the
affected area thoroughly with soap and water.
• When replacing a toner or waste toner container or consumables with toner,
make sure that the toner does not splatter. Put the waste consumables in a bag
after they are removed. For consumables with a lid, make sure that the lid is shut.
