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. Always unplug the power cord from the power source before you move the product. Before you
move the machine, arrange the power cord so it will not fall under the machine.
5. Disconnect all peripheral units (finisher, LCT, etc.) from the mainframe before you move the
machine.
6. 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.
7. The machine drives some of its components when it completes the warm-up period. Be careful to
keep hands away from the mechanical and electrical components as the machine starts operation.
8. 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.
9. To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and
aerosols.
10. Do not use flammable sprays or solvent in the vicinity of the machine. Also, avoid placing these
items in the vicinity of the machine. Doing so could result in fire or electric shock.
11. To avoid fire or explosion, never use an organic cleaner near any part that generates heat.
12. Clean the floor completely after accidental spillage of silicone oil or other materials to prevent
slippery surfaces that could cause accidents leading to hand or leg injuries.
13. Never remove any safety device unless it requires replacement. Always replace safety devices
immediately.
14. Never do any procedure that defeats the function of any safety device.
15. Modification or removal of a safety device (fuse, switch, etc.) could lead to a fire and personal
injury. Always test the operation of the machine to ensure that it is operating normally and safely
after removal and replacement of any safety device.
16. For replacements use only the correct fuses or circuit breakers rated for use with the machine.
Using replacement devices not designed for use with the machine could lead to a fire and personal
injuries.
17. For machines installed with the ADF/ARDF:
When a thick book or three-dimensional original is placed on the exposure glass and the ARDF
cover is lowered, the back side of the ARDF rises up to accommodate the original. Therefore, when
closing the ARDF, please be sure to keep your hands away from the hinges at the back of the
ARDF.
18. When using a vacuum cleaner around the machine, keep others away from the cleaner, especially
small children.
19. For machines installed with the anti-tip components:
The anti-tip components are necessary for meeting the requirements of IEC60950-1, the
international standard for safety. The aim of these components is to prevent the products, which
are heavy in weight, from toppling as a result of people running into or leaning onto the products,
which can lead to serious accidents such as persons becoming trapped under the product. (U.S.:
UL60950-1, Europe: EN60950-1) Therefore, removal of such components must always be with the
consent of the customer. Do not remove them at your own judgment.
20. NEVER touch the AC circuits on the PSU board to prevent electric shock caused by residual
charge. Residual charge of about 100V-400V remains in the AC circuits on the PSU board for
several months even when the board has been removed from the machine after turning off the
machine power and unplugging the power cord.
Health Safety Conditions
1. For the machines installed with the ozone filters:
•Never operate the machine without the ozone filters installed.
•Always replace the ozone filters with the specified types at the proper intervals.
2. The machine, which use high voltage power source, can generate ozone gas. High ozone density
is harmful to human health. Therefore, locate the machine in a large well ventilated room that has
an air turnover rate of more than 50m3/hr/person.
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 with exceptions on some
machines where the installation can be handled by the user.
Safety and Ecological Notes for Disposal
•Do not incinerate toner bottles or used toner. Toner dust may ignite suddenly when exposed to an
open flame.
•Dispose of used toner, developer, organic photoconductors, and AIO unit in accordance with local
regulations. (These are non-toxic supplies.)
•Dispose of replaced parts in accordance with local regulations.
•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,
bottles (including used toner and empty bottles and cartridges), and AIO unit 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.
•Do not use a vacuum cleaner to remove spilled toner (including used toner). Vacuumed toner may
cause a fire or explosion due to sparks or electrical contact inside the cleaner. However, it is
possible to use a cleaner designed to be dust explosion-proof. If toner is spilled over the floor,
sweep up spilled toner slowly and clean up any remaining toner with a wet cloth.
Handling the development unit cooling system
For the machines installed the development cooling system:
1. The development unit cooling system circulates propylene glycol from a sealed tank through hoses
that pass behind cooling plates on the sides of each development unit.
2. The coolant tank is located at the bottom of the cooling box on the back of the main machine.
3. Always obey local laws and regulations if you need to dispose of a tank or the propylene glycol
coolant.
4. The tank must never be emptied directly into a local drainage system, river, pond, or lake.
5. Contact a professional industrial waste disposal organization and ask them to dispose of the tank.
Lithium Batteries for Taiwan
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.
Safety Instructions for the Color Controller
Fuse
The color controller uses a double pole fuse. If this fuse blows, be sure to replace it with an identical
fuse.
Batteries
Always replace a battery with the same type of battery prescribed for use with the color controller unit.
Replacing a battery with any type other than the one prescribed for use could cause an explosion.
•Never discard used batteries by mixing them with other batteries or other refuse.
•Always remove used batteries from the work site and dispose of them in accordance with local
laws and regulations regarding the disposal of such items.
