(1) Do not touch the damaged LCD. This MFP has LCD in control panel. Noxious liquid to human body exists in the
LCD. If it is got into mouth, immediately see a doctor. If it is got into eyes or on skin, immediately wash off over 15
minutes with flowing water and see a doctor.
Caution 2>>Precaution related electric shock or fire
It is possible to get electric shock or burn by fire if you don't fallow the instructions of the manual.
(1) Use exact voltage. Please do use an exact voltage and wall socket. If not, a fire or an electric leakage can be
caused.
(2) Use authorized power code. Do use the power code supplied with MFP. A fire can be occurred when over current
flows in the power code.
(3) Do not insert many codes in an outlet. If do, a fire can be occurred due to flow over current in an outlet.
(4) Do not put water or extraneous matter in the MFP. Please do not put water, other liquid, pin, clip, etc. It can cause a
fire, electric shock, or malfunction. If it is happened, turn off the power and remove the power plug from outlet imme-
diately.
(5) Do not touch the power plug with wet hand. When servicing, do remove the power plug from outlet. And do not insert
or take off it with wet hand. Electric shock can be occurred.
(6) Caution when inserting or taking off the power plug. The power plug has to be inserted completely. If not, a fire can
be caused due to poor contact. When taking off the power plug, do grip the plug and take it off. If grip the line and
pull over, it could be damaged. A fire or electric shock could cause.
(7) Management of power code. Do not bend, twist, or bind it and place other materials on it. Also, do not fix it with sta-
ples. If the power code gets damage, a fire or electric shock can be caused. A damaged power code must be
replaced immediately. Do not repair the damaged part and reuse it. A repaired part with plastic tape can be occurred
a fire or electric shock. Do not spread chemicals on the power code. Do not spread insecticide on the power code. A
fire or electric shock can be occurred due to thinner(weak) cover of the power code.
(8) Check whether the power outlet and the power plug are damaged, pressed, chopped, or blazing fire or not. When
such inferiorities are found, repair it immediately. Do not make it pressed or chopped when moving the machine.
(9) Caution when thundering, and being flash of lightening. It causes a fire or electric shock. Take the power plug off
when thundering. Do not touch cable and device when thundering and being flash of lightening.
(10) Do avoid the place where is moisture or has dust. Do not install the MFP in where have lots of dust or around
humidifier. A fire can be occurred. A plug part need to clean well with dried fabric to remove dust. If water drops are
dripped on the place covered with dust, a fire can be occurred.
(11) Avoid direct sunlight. Do not install the MFP near to window where directly contacts to the sunlight. If the machine
contacts sunlight long time, the machine cannot work properly because inner temperature of the machine is getting
higher. A fire can be caused.
(12) Turn off the power and take off the plug when a smoke, strange smell, or sound from the machine. If you keep
using it, a fire can be occurred.
(13) Do not insert steel or metal piece inside/outside of the machine. Do not put steel or metal piece into a ventilator. An
electric shock could be happened.

Precautions
1.3 ESD Precautions
Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called
"Electrostatically Sensitive (ES) Devices", or ESDs. Examples of typical ESDs are: integrated circuits, some field effect
transistors, and semiconductor "chip" components.
The techniques outlined below should be followed to help reduce the incidence of component damage caused by static
electricity.
Caution >>Be sure no power is applied to the chassis or circuit, and observe all other safety
precautions.
1. Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off any electro-
static charge on your body by touching a known earth ground. Alternatively, employ a commercially available wrist
strap device, which should be removed for your personal safety reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface, such as alu-
minum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assembly.
3. Use only a grounded tip soldering iron to solder or desolder ESDs.
4. Use only an "anti-static" solder removal device. Some solder removal devices not classified as "anti-static" can gener-
ate electrical charges sufficient to damage ESDs.
5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to damage
ESDs.
6. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most replace-
ment ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a comparable conduc-
tive material.
7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protec-
tive material to the chassis or circuit assembly into which the device will be installed.
8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until com-
pletely plugged or soldered into the circuit.
9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing
together of clothing fabric and lifting one's foot from a carpeted floor, can generate static electricity sufficient to dam-
age an ESD.
