Safety
Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that
the machine and peripheral power cords are unplugged.
2. The plug should be near the machine and easily accessible.
3. Note that some components of the machine and the paper tray unit are supplied with
electrical voltage even if the main power switch is turned off.
4. Always unplug the power cord from the power source before you move the product. Before
you move the machine, arrange the power cord so it will not fall under the machine.
5. Disconnect all peripheral units (finisher, LCT, etc.) from the mainframe before you move the
machine.
6. 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.
7. 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.
8. 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.
9. To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and
aerosols.
10. Do not use flammable sprays or solvent in the vicinity of the machine. Also, avoid placing
these items in the vicinity of the machine. Doing so could result in fire or electric shock.
11. To avoid fire or explosion, never use an organic cleaner near any part that generates heat.
12. Clean the floor completely after accidental spillage of silicone oil or other materials to
prevent slippery surfaces that could cause accidents leading to hand or leg injuries.
13. Never remove any safety device unless it requires replacement. Always replace safety
devices immediately.
14. Never do any procedure that defeats the function of any safety device.
