Important Safety Notices
Important Safety Notices
Prevention of Physical Injury
1. Before disassembling or assembling parts of the main machine and peripherals, make sure that the
power cord of the main machine is unplugged.
2. The wall outlet 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. 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.
• To prevent a fire or explosion, keep the machine away from flammable liquids, gases, and
aerosols.
Health Safety Conditions
1. Toner and developer is non-toxic, but if you get either of them in your eyes by accident, it may
cause temporary eye discomfort. Immediately wash eyes with plenty of water. If unsuccessful, get
medical attention.
2. This machine, which uses a high voltage power source, can generate ozone gas. High ozone
density is harmful to human health. Therefore, the machine must be installed in a well-ventilated
room.
Observance of Electrical Safety Standards
1. This machine and its peripherals must be serviced 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.

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 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.
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.
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.

2. Installation
Moving 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 40 kg (88.2 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.
20
Installation Requirements
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. If Paper Feed Unit are attached, remove them.
3. Lift the printer with two people 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.
4. If you removed Paper Feed Unit, reattach them.
• Be sure to move the printer horizontally. To prevent toner from scattering, move the printer
slowly.

Avoid touching areas of the PSU that may carry charge.
General Cautions
• Do not hold down the power switch for 6 seconds or longer when turning off the machine. Doing
so may result in damage to the hard disk or memory, leading to malfunctions.
• Before disassembling or assembling parts of the main machine and peripherals, make sure that the
power cord of the main machine is unplugged.Since this machine uses a DC switch, there is a weak
current even after the power cord is unplugged.
Follow the steps below when disassembling the machine.
1. Press the power switch off.
2. Unplug the power cord.
3. Press the power switch once to discharge the remaining current.
When the power cord is plugged in, the machine may power itself on even though the power switch
button is not pressed.
