Before disassembling or assembling parts of the machine and peripherals, make sure that the machine and peripheral power cords are unplugged.
The plug should be near the machine and easily accessible.
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.
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.
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, because the machine starts making copies as soon as the warm-up period is completed.
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.
To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and aerosols.
