Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that
they 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. 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.
5. If the [Start] key is pressed before the machine completes the warm-up period (the [Start] key
starts blinking red and green ), keep hands away from the mechanical and the electrical
components as the machine starts making copies as soon as the warm-up period is
completed.
6. 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.
7. Always connect the power cord directly into a wall outlet. Never use an extension cord.
8. Inspect the power cord for damage. Never cut or attempt to modify the power cord in any way.
9. Keep the machine away from dust and high humidity. Never expose the machine to corrosive
gases.
10. Never use flammable liquids or aerosols around the machine.
11. Never handle the power cord or plug with wet hands.
