Safety Notices
Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the machine and peripherals, make sure that the
machine power cord is unplugged.
2. The wall outlet should be near the machine and easily accessible.
3. 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.
4. 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.
5. 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
Toner is 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
The machine and its peripherals must be serviced 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, the maintenance unit which includes developer or the organic
photoconductor in accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
• To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and
aerosols. A fire or an explosion might occur.

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.
• Do not use the cleaner to suck spilled toner (including used toner). Sucked toner may cause firing
or explosion due to electrical contact flickering inside the cleaner. However, it is possible to use the
cleaner designed for dust explosion-proof purpose. If toner is spilled over the floor, sweep up
spilled toner slowly and clean remainder with wet cloth.
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.
• Turn off the main switch before attempting any of the procedures in the Laser Optics Housing Unit
section. Laser beams can seriously damage your eyes.

Moving and Transporting the Machine
• It is dangerous to handle the power cord plug with wet hands. Doing so could result in electric
shock.
• Unplug the power cord from the wall outlet before you move the machine. While moving the
machine, take care that the power cord is not damaged under the machine. Failing to take these
precautions could result in fire or electric shock.
• When disconnecting the power cord from the wall outlet, always pull the plug, not the cord. Pulling
the cord can damage the power cord. Use of damaged power cords could result in fire or electric
shock.
• The printer weighs approximately 12.7 kg (28 lb.). When moving the printer, use the inset grips on
both sides, and lift slowly in pairs. The printer will break or cause injury if dropped.
• When moving the printer after use, do not take out any of the toners, nor the waste toner bottle to
prevent toner spill inside the printer.
• Do not hold the control panel while moving the printer. Doing so may damage the control panel,
cause a malfunction, or result in injury.
• Be careful when moving the printer. Take the following precautions:
• Turn off the main power.
• Close all covers and trays, including the front cover and bypass tray.
• If optional paper feed units are attached, remove them from the printer and move them separately.
• Be sure to place the printer on a smooth and stable place.
• Keep the printer level and carry it carefully, taking care not to jolt or tip it. Rough handling may
cause a malfunction or damage the hard disk or memory, resulting in loss of stored files.
• Protect the printer from strong shocks. Impact can damage the hard disk and cause stored files to
be lost. As a precautionary measure, files should be copied to another computer.
2. Installation
16

1. Be sure to check the following:
The power switch is turned off.
The power cord is unplugged from the wall outlet.
The interface cable is unplugged from the printer.
2. Lift the printer by using the inset grips on both sides of the printer, and then move it
horizontally to the place where you want to install it.
• Be sure to move the printer horizontally. To prevent toner from scattering, move the printer
slowly.
