Prevention of Physical Injury
1. Before disassembling or assembling parts of the copier and peripherals, make sure that the
copier power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. Note that some components of the copier 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 copier completes the warm-up period (the Start key
starts blinking red and green alternatively), keep hands away from the mechanical 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 copier 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.

may cause temporary eye discomfort. Immediately wash eyes with plenty of water. If
unsuccessful, get medical attention.

ozone density is harmful to human health. Therefore, the machine must be installed in a
