Safety Precautions for This Machine
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the machine and peripherals, make sure that the machine
power cord is unplugged.
2. The wall outlet should be near the machine and easily accessible.
3. Note that some components of the machine 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. The inside and the metal parts of the fusing unit become extremely hot while the machine is operating.
Be careful to avoid touching those components with your bare hands.
HEALTH SAFETY CONDITIONS
1. Never operate the machine 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 machine and its peripherals must be installed and maintained by a customer service representative
who has completed the training course on those models.
2. The NVRAM on the system control board has a lithium battery which can explode if replaced incor-
rectly. Replace the NVRAM only with an identical one. The manufacturer recommends replacing the
entire NVRAM. Do not recharge or burn this battery. Used NVRAM must be handled in accordance
with local regulations.
3. The danger of explosion exists if the battery on the controller board is incorrectly replaced. Replace
the battery only with the equivalent type recommended by the manufacturer. Discard the used con-
troller board battery in accordance with the manufacturers' instructions.
SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
1. Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an
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.
4. When keeping used lithium batteries in order to dispose of them later, do not put more than 100
batteries per sealed box. Storing larger numbers or not sealing them apart may lead to chemical
reactions and heat build-up.
