Safety
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the machine and peripherals, make sure
that they are unplugged.
2. The plug 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. If the [Start] key is pressed before the machine completes the warm-up period (the
[Start] key starts blinking red and green ), keep hands away from the mechanical and
the electrical components as the machine 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
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 types at the proper 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.
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.)
