IMPORTANT SAFETY NOTICES
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 peripherals are supplied
with electrical voltage even if the main 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. 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.
6. The copier is not attached to the table. Pushing the copier too hard may
cause it to drop onto the floor. While moving the copier, push the table.
7. When the main switch is turned on, the machine will suddenly start turning to
perform the developer initialization. Keep hands away from any mechanical
and electrical components during this period.
HEALTH SAFETY CONDITIONS
1. Never operate the copier without the ozone filters installed.
2. Always replace the ozone filters with the specified ones at the specified
intervals.
3. Toner and developer are non-toxic, but if you get either of them in your eyes
by accident, it may cause temporary eye discomfort. Try to remove with eye
drops or flush with water as first aid. If unsuccessful, get medical attention.
OBSERVANCE OF ELECTRICAL SAFETY STANDARDS
1. The copier and its peripherals must be installed and maintained by a
customer service representative who has completed the training course on
those models.
2. Caution: The RAM pack on the main control board has a lithium battery
which can explode if replaced incorrectly. Replace the RAM pack only with
an identical one. The manufacturer recommends replacing the entire RAM
pack. Do not recharge or burn this battery. Used RAM packs must be
handled in accordance with local regulations.
