 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 the optional tray heater and the optional anti-condensation
heaters 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.
HEALTH SAFETY CONDITIONS
1. 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.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate toner cartridges or used toner. Toner dust may ignite
suddenly when exposed to open flame.
2. Dispose of used toner, developer, and organic photoconductors in
accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
