Important Safety Notices
Safety
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. For the model with ozone filters installed at the factory, never operate the machine without the
ozone filters installed.
2. For the model with ozone filters installed at the factory, always replace the 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.)
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.
The danger of explosion exists if a battery of this type is incorrectly replaced. Replace
only with the same or an equivalent type recommended by the manufacturer. Discard
used batteries in accordance with the manufacturer’s instructions.
Handling Toner
Work carefully when removing paper jams or replacing toner bottles or cartridges to avoid
spilling toner on clothing or the hands.
If toner is inhaled, immediately gargle with large amounts of cold water and move to a well
ventilated location. If there are signs of irritation or other problems, seek medical attention.
If toner gets on the skin, wash immediately with soap and cold running water.
If toner gets into the eyes, flush the eyes with cold running water or eye wash. If there are
signs of irritation or other problems, seek medical attention.
If toner is swallowed, drink a large amount of cold water to dilute the ingested toner. If there
are signs of any problem, seek medical attention.
If toner spills on clothing, wash the affected area immediately with soap and cold water. Never
use hot water! Hot water can cause toner to set and permanently stain fabric.
Always store toner and developer supplies such as toner and developer packages, cartridges,
and bottles (including used toner and empty bottles and cartridges) out of the reach of
children.
Always store fresh toner supplies or empty bottles or cartridges in a cool, dry location that is
not exposed to direct sunlight.

Laser Safety
The Center for Devices and Radiological Health (CDRH) prohibits the repair of laser-based optical
units in the field. The optical housing unit can only be repaired in a factory or at a location with the
requisite equipment. The laser subsystem is replaceable in the field by a qualified Customer
Engineer. The laser chassis is not repairable in the field. Customer engineers are therefore
directed to return all chassis and laser subsystems to the factory or service depot when
replacement of the optical subsystem is required.
Use of controls, or adjustment, or performance of procedures other than those specified
in this manual may result in hazardous radiation exposure.
WARNING FOR LASER UNIT
WARNING:
Turn off the main switch before attempting any of the procedures in the Laser Unit
section. Laser beams can seriously damage your eyes.
CAUTION MARKING:
Safety Precautions for This Machine
Before moving the mainframe:
Disconnect all peripheral units (finisher, LCT, etc.) from the mainframe.
Hold the four holders of the mainframe to lift the mainframe. For details, see the “Copier
Installation” in the field service manual.
