described in the reference materials (service manuals, technical bulletins, operating instructions,
and safety guidelines for customer engineers).
• Use only consumable supplies and replacement parts designed for use with the machine.
Before Installation, Maintenance
Shipping and Moving the Machine
• Personnel moving or working around the machine should always wear proper clothing and
footwear. Never wear loose fitting clothing or accessories (neckties, loose sweaters, bracelets,
etc.) or casual footwear (slippers, sandals, etc.) when lifting or moving the machine.
• Always unplug the power cord from the power source before you move the machine. Before you
move the product, arrange the power cord so it will not fall under the machine.
Power
• Always disconnect the power plug before doing any replacement procedure. After switching off
the machine, power is still supplied to the main machine and other devices. To prevent electrical
shock, switch the machine off, wait for a few seconds, then unplug the machine from the power
source.
• Before you do any checks or adjustments after turning the machine off, work carefully to avoid
injury. After removing covers or opening the machine to do checks or adjustments, never touch
electrical components or moving parts (gears, timing belts, etc.).
2

• After turning the machine on with any cover removed, keep your hands away from electrical
components and moving parts. Never touch the cover of the fusing unit, gears, timing belts, etc.
Installation, Replacement, and Adjustments
• After installation, replacement, or adjustment, always check the operation of the machine to make
sure that it is operating normally. This ensures that all shipping materials, protective materials, wires
and tags, metal brackets, etc., removed for installation, have been removed and that no tools
remain inside the machine. This also ensures that all release interlock switches have been restored
to normal operation.
• Never use your fingers to check moving parts causing spurious noise. Never use your fingers to
lubricate moving parts while the machine is operating.
Special Tools
• Use only standard tools approved for machine maintenance.
• For special adjustments, use only the special tools and lubricants described in the service manual.
Using tools incorrectly, or using tools that could damage parts, could damage the machine or
cause injuries.
During Maintenance
General
• Before you begin a maintenance procedure: 1) Switch the machine off, 2) Disconnect the power
plug from the power source, 3) Allow the machine to cool for at least 10 minutes.
• Avoid touching the components inside the machine that are labeled as hot surfaces.
Safety Devices
• Never remove any safety device unless it requires replacement. Always replace safety devices
immediately.
• Never do any procedure that defeats the function of any safety device. Modification or removal of
a safety device (fuse, switch, etc.) could lead to a fire and personal injury. Always test the
3

operation of the machine to ensure that it is operating normally and safely after removal and
replacement of any safety device.
• 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.
Organic Cleaners
• During preventive maintenance, never use any organic cleaners (alcohol, etc.) other than those
described in the service manual.
• Make sure the room is well ventilated before using any organic cleaner. Use organic solvents in
small amounts to avoid breathing the fumes and becoming nauseous.
• Switch the machine off, unplug it, and allow it to cool before doing preventive maintenance. To
avoid fire or explosion, never use an organic cleaner near any part that generates heat.
• Wash your hands thoroughly after cleaning parts with an organic cleaner to prevent contamination
of food, drinks, etc. which could cause illness.
• Clean the floor completely after accidental spillage to prevent slippery surfaces that could cause
accidents leading to hand or leg injuries. Use dry rags to soak up spills.
Power Plug and Power Cord
• Before servicing the machine (especially when responding to a service call), always make sure that
the power plug has been inserted completely into the power source. A partially inserted plug could
lead to heat generation (due to a power surge caused by high resistance) and cause a fire or other
problems.
• Always check the power plug and make sure that it is free of dust and lint. Clean it if necessary. A
dirty plug can generate heat which could cause a fire.
• Inspect the length of the power cord for cuts or other damage. Replace the power cord if
necessary. A frayed or otherwise damaged power cord can cause a short circuit which could lead
to a fire or personal injury from electrical shock.
• Check the length of the power cord between the machine and power supply. Make sure the power
cord is not coiled or wrapped around any object such as a table leg. Coiling the power cord can
cause excessive heat to build up and could cause a fire.
• Make sure that the area around the power source is free of obstacles so the power cord can be
removed quickly in case of an emergency.
• Make sure that the power cord is grounded (earthed) at the power source with the ground wire on
the plug.
4

• Connect the power cord directly into the power source. Never use an extension cord.
• When you disconnect the power plug from the power source, always pull on the plug, not the
cable.
After Maintenance
Disposal of Used Items
• Never incinerate used toner, toner cartridges, or AIO units.
• Toner thrown into a fire can ignite or explode and cause serious injury. At the work site always
carefully wrap used toner and toner cartridges with plastic bags to avoid spillage before disposal
or removal.
• Always dispose of used items (developer, toner, toner cartridges, OPC drums, AIO units, etc.) in
accordance with the local laws and regulations regarding the disposal of such items.
• To protect the environment, never dispose of this product or any kind of waste from consumables at
a household waste collection point. Dispose of these items at one of our dealers or at an
authorized collection site.
• Return used drums to the service center for handling in accordance with company policy regarding
the recycling or disposal of such items.
Points to Confirm with Operators
At the end of installation or a service call, instruct the user about use of the machine. Emphasize the
following points.
• Show operators how to remove jammed paper and troubleshoot other minor problems by
following the procedures described in the operating instructions.
• Point out the parts inside the machine that they should never touch or attempt to remove.
• Confirm that operators know how to store and dispose of consumables.
• Make sure that all operators have access to an operating instruction manual for the machine.
• Confirm that operators have read and understand all the safety instructions described in the
operating instructions.
• Demonstrate how to turn off the power and disconnect the power plug (by pulling the plug, not the
cord) if any of the following events occur: 1) something has spilled into the product, 2) service or
repair of the product is necessary, 3) the product cover has been damaged.
5

• Caution operators about removing paper fasteners around the machine. They should never allow
paper clips, staples, or any other small metallic objects to fall into the machine.
Special Safety Instructions for Toner
Accidental Physical Exposure
• 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.
Handling and Storing Toner
• Toner, used toner, and developer are extremely flammable.
• Never store toner, developer, toner cartridges, or toner bottles (including empty toner bottles or
cartridges), or AIO units in a location where they will be exposed to high temperature or an open
flame.
• 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.
• Always store toner and developer supplies such as toner and developer packages, cartridges,
bottles (including used toner and empty bottles and cartridges) and AIO units out of the reach of
children.
6

• Always store fresh toner supplies or empty bottles or cartridges in a cool, dry location that is not
exposed to direct sunlight.
Toner Disposal
• Never attempt to incinerate toner, used toner, or empty toner containers (bottles or cartridges).
Burning toner can explode and scatter, causing serious burns.
• Always wrap used toner and empty toner bottles and cartridges in plastic bags to avoid spillage.
Follow the local laws and regulations regarding the disposal of such items.
• Dispose of used toner and toner cartridges at one of our dealers or at an authorized collection site.
Always dispose of used toner cartridges and toner bottles in accordance with the local laws and
regulations regarding the disposal of such items.
Safety Instructions for the 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,
because 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. If the machine has ozone filters, never operate the machine without the ozone filters installed.
Always replace the ozone filters with the specified types at the proper intervals.
7

2. To avoid possible accumulation of ozone in the work area, locate the machine in a large well
ventilated room that has an air turnover rate of more than 30m3/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.
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. Never 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.
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.
8

• Use of controls, or adjustment, or performance of procedures other than those specified in this
manual may result in hazardous radiation exposure.
• Turn off the main switch before attempting any of the procedures in the Laser Unit section. Laser
beams can seriously damage your eyes.
RoHS Compliance
These machines are fully compliant with Chinese RoHS and contain no restricted materials such as lead,
mercury, cadmium, hexavalent chrome, polybrominated biphenyl, or polybrominated diphenyl ether.
