Safety Notices
Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that
the machine power cord is unplugged.
2. The wall outlet should be near the machine and easily accessible.
3. If any adjustment or operation check has to be made with exterior covers off or open while
the main switch is turned on, keep hands away from electrified or mechanically driven
components.
4. The machine drives some of its components when it completes the warm-up period. Be
careful to keep hands away from the mechanical and electrical components as the machine
starts operation.
5. The inside and the metal parts of the fusing unit become extremely hot while the machine is
operating. Be careful to avoid touching those components with your bare hands.
Health Safety Conditions
Toner is non-toxic, but if you get either of them in your eyes by accident, it may cause temporary
eye discomfort. Try to remove with eye drops or flush with water as first aid. If unsuccessful, get
medical attention.
Observance of Electrical Safety Standards
The machine and its peripherals must be serviced by a customer service representative who
has completed the training course on those models.
The Controller board on this machine contains a lithium battery. The danger of
explosion exists if a battery of this type is incorrectly replaced. Replace only with the
same or an equivalent type recommended by the manufacturer. Discard batteries in
accordance with the manufacturer's instructions and local regulations.

Safety and Ecological Notes for Disposal
1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when
exposed to an open flame.
2. Dispose of used toner, the maintenance unit which includes developer or the organic
photoconductor in accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
To prevent a fire or explosion, keep the machine away from flammable liquids, gases,
and aerosols. A fire or an explosion might occur.
Handling Toner
Work carefully when removing paper jams or replacing toner bottles or cartridges to avoid
spilling toner on clothing or the hands.
If toner is inhaled, immediately gargle with large amounts of cold water and move to a well
ventilated location. If there are signs of irritation or other problems, seek medical attention.
If toner gets on the skin, wash immediately with soap and cold running water.
If toner gets into the eyes, flush the eyes with cold running water or eye wash. If there are
signs of irritation or other problems, seek medical attention.
If toner is swallowed, drink a large amount of cold water to dilute the ingested toner. If there
are signs of any problem, seek medical attention.
If toner spills on clothing, wash the affected area immediately with soap and cold water.
Never use hot water! Hot water can cause toner to set and permanently stain fabric.
Always store toner and developer supplies such as toner and developer packages,
cartridges, and bottles (including used toner and empty bottles and cartridges) out of the
reach of children.
Always store fresh toner supplies or empty bottles or cartridges in a cool, dry location that is
not exposed to direct sunlight.
