Safety Instructions for this Machine

Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that the machine
and peripheral power cords 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.
7. To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and aerosols.
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.
2. The NVRAM on the system control board 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. Do not recharge or burn this battery. Used NVRAM must be handled in accordance
with local regulations.
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.
