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.

Main Machine Installation
• If you have to move the machine when the optional paper tray unit is attached, do not push on the
main unit's top section. Doing so can cause the optional paper tray unit to detach, possibly resulting
in injury.
• 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 machine weighs approximately 22.5 kg (49.6 lb.). When moving the machine, use the inset
grips on both sides, and lift slowly in pairs. The machine will break or cause injury if dropped.
• Do not hold the control panel while moving the machine. Doing so may damage the control panel,
cause a malfunction, or result in injury.
• Be careful when moving the machine. Take the following precautions:
• Close all covers and trays, including the front cover and by-pass tray.
• If optional paper feed units are attached, remove them from the machine and move them

SD Card Appli Move
SD Card Appli Move
Overview
Since there are only two SD card slots (one of them is a service slot), three or more SD card applications
cannot be used simultaneously.
However, if multiple SD card applications are merged, three or more SD card options can be used.
This function is referred to as the “SD card merge function.”
The “SD card merge function” is a function which enables the use of three or more functions within the
capacity of two SD cards by physically transferring the function of one SD card to other SD cards (all SD
card options can be stored in two SD cards).
However, SD card applications are under license, therefore, since an SD card license after merge is
transferred to the target SD card, it cannot be used even if it is moved to the target machine.
Also, a process to prevent illegal copying is performed.
The service program "SD Card Appli Move" (SP5-873) lets you move application programs from one
SD card to another SD card.
Notes on Using the SD Merge Function
• The data necessary for authentication is transferred with the application program from an SD card
to another SD card. Authentication fails if you try to use the SD card after you move the application
program from one card to another card.
• Do not use the SD card if it has been used before for other purposes. Normal operation is not
guaranteed when such an SD card is used.
• An SD card, which becomes empty after moving the data in it to another card, cannot be reused.
• After moving the data in an SD card to another card so that the source card becomes empty, keep
the empty card in place by, for example, affixing it near the SD card slot with adhesive tape. This is
done for the following reasons:
• The SD card can be the only proof that the user is licensed to use the application program.
• You may need to check the SD card and its data to solve a problem in the future.

General Cautions
Notes on the Main Power Switch
The main power button of this machine has been changed to a push-button switch (push button) from the
conventional rocker switch. The push switch has characteristics and specifications different from the
rocker switch. Care must be taken when replacing and adjusting parts.
Characteristics of the Push Switch (DC Switch)
Power is supplied to the machine even when the main power switch is turned OFF.
The push switch in this machine uses DC (direct current). Therefore, if the AC power cord is
connected to an electrical outlet, power is supplied to the controller board, the operation unit and
other modules even when the main power is turned OFF. When replacing the controller board and
the operation unit in this state, not only these boards, it will damage other electrical components.
So, when performing maintenance work such as replacing parts, in addition to turning off the main
power with the push switch, always unplug the AC power cord.
When you disconnect the power cord from the AC wall outlet, inside the machine there is still
residual charge.
When you disconnect the power cord from the AC wall outlet, inside the machine for a while there
is still residual charge. Therefore, if you remove boards in this state, it can cause a blown fuse or
memory failure.
-- How to remove the residual charge inside the machine--
After you unplug the power cord from the AC wall outlet, in order to remove the residual charge
from inside the machine, be sure to press the main power switch. Thus, the charge remaining in the
machine is released, and it is possible to remove boards.
When you reconnect the AC power cord into an AC wall outlet, the machine will start
automatically.
In order to remove the residual charge, push the main power switch while you disconnect the AC
power cord. At that time, the power ON flag inside the machine is set. Therefore, after you finish
work on the machine and reconnect the power cord to the AC, even if you do not press the main
power switch, the machine will start automatically and the moving parts will begin to move. When
working on moving parts, be careful that fingers or clothes do not get caught.
53
Page 56
4. Replacement and Adjustment
• Automatic restart deals with cases when you accidentally unplugged the AC power cord or
unexpected power outages. By keeping the power flag ON, after the resumption of power, the
machine will start up automatically.
In rare cases, when you reconnect the AC power cord to a power outlet, the machine does not start
automatically. In this case, the machine has not failed. The cause is due to the timing of releasing the
residual charge. If you press the main power switch while the residual charge was already released, the
power ON flag will not be set. At this time, start the machine manually by pressing the main power
switch.
Shutdown Method
1. Press the main power switch [A] on the left side of the machine.
After the shutdown process, the main power is turned off automatically.
When the shutdown is complete
Operation panel LED: Off
2. Take out the power cord.
3. Wait 3 minutes (this is the time required if you will remove the rear cover and access the
interior of the machine, to take out the controller board for example).
Note: If some LEDs on any of the boards are blinking or lit, current is still flowing.
How to start from shutdown
To start the machine, press the main power switch. However, if you press the main power switch
between the beginning and the end of a shutdown, the machine will not start.
54
Page 57
General Cautions
Forced Shutdown
In case normal shutdown does not complete for some reason, the machine has a forced shutdown
function.
To make a forced shutdown, press and hold the main power switch for 6 seconds.
In general, do not use the forced shutdown.
• Forced shutdown may damage the hard disk and memory, and can cause damage to the machine.
Use a forced shutdown only if it is unavoidable.
