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 paper tray unit 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. 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.
HEALTH SAFETY CONDITIONS
1. Always replace the ozone filters with the specified ones at the specified
intervals.
2. 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. The RAM board on the system control board has a lithium battery
which can explode if replaced incorrectly. Replace the battery only with
an identical one. The manufacturer recommends replacing the entire
RAM board. Do not recharge or burn this battery. Used batteries must
be handled in accordance with local regulations.
