Safety
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the printer and peripherals, make sure
that the printer power cord is unplugged.
2. The wall outlet should be near the printer and easily accessible.
3. Note that some components of the printer 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 printer
is operating. Be careful to avoid touching those components with your bare hands.
6. To prevent a fire or explosion, keep the machine away from flammable liquids, gases,
and aerosols.
HEALTH SAFETY CONDITIONS
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
The printer 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 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.
