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. 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 metal parts of the fusing unit and other internal components become
extremely hot while the copier is operating. Avoid touching those
components with your bare hands.
HEALTH SAFETY CONDITIONS
1. Never operate the copier without the ozone filters installed.
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
the machines.
2. The NVRAM has a lithium battery which can explode if replaced incorrectly.
Replace the NVRAM only with an identical one. The manufacturer
recommends replacing the entire NVRAM. Never attempt to recharge or
incinerate this battery. Used NVRAMs must be handled in accordance with
local regulations regarding the disposal of such items.s
