SAFETY
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the printer and peripherals, make sure
that the printer and peripheral power cords are unplugged.
2. The power source should be near the printer and easily accessible.
3. Note that some components of the printer 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

driven components.

and the electrical components as the copier 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 printer
is operating. Be careful to avoid touching those components with your bare hands.
7. To prevent a fire or explosion, keep the machine away from flammable liquids, gases,
and aerosols.
