1. Before servicing, unplug the AC power cord to prevent an electric shock.
2. When replacing parts, use only the manufacturer's recommended components.
3. Check the condition of the power cord. Replace if wear or damage is evident.
4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.
5. Before returning the serviced equipment to the customer, be sure to perform the following insulation resistance test to prevent
the customer from being exposed to shock hazards.
1.1. For Service Technicians
•Repair service shall be provided in accordance with repair technology information such as service manual so as to pre-
vent fires, injury or electric shock, which can be caused by improper repair work.
1. When repair services are provided, neither the products nor their parts or members shall be remodeled.
2. If a lead wire assembly is supplied as a repair part, the lead wire assembly shall be replaced.
3. FASTON terminals shall be plugged straight in and unplugged straight out.
•ICs and LSIs are vulnerable to static electricity.
When repairing, the following precautions will help prevent recurring malfunctions.
1. Cover the plastic part's boxes with aluminum foil.
2. Ground the soldering irons.
3. Use a conductive mat on the worktable.
4. Do not touch the IC or LSI pins with bare fingers.
1.2. AC Caution

1.3. Personal Safety Precautions
1.3.1. Moving Sections of the Unit
Be careful not to let your hair, clothes, fingers, accessories, etc., become caught in any moving sections of the unit.
The moving sections of the unit are the rollers and a gear. There is a separation roller and a document feed roller which are rotated
by the document feed motor. A gear rotates the two rollers. Be careful not to touch them with your hands, especially when the unit
is operating.
1.3.2. Live Electrical Sections
All the electrical sections of the unit supplied with AC power by the AC power cord are live.
Never disassemble the unit for service with the AC power supply plugged in.
CAUTION:
AC voltage is supplied to the primary side of the power supply unit. Therefore, always unplug the AC power cord before disas-
sembling for service.

KX-FLC418RU
1.4. Service Precautions
1.4.1. Laser Beam and Fuser Unit Section
• The printer of this unit utilizes a laser. Use of controls or adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
• The fuser unit is inside of the unit and gets hot. Do not touch it when removing the jammed paper or cleaning the lower glass.
1.4.2. Precautions to Prevent Damage from Static Electricity
Electrical charges accumulate on a person. For instance, clothes rubbing together can damage electric elements or change their
electrical characteristics. In order to prevent static electricity, touch a metallic part that is grounded to release the static electricity.
Never touch the electrical sections such as the power supply unit, etc.

7
KX-FLC418RU
1.5. For Best Performance
• To extend the life of the drum unit, the unit should never be turned OFF immediately after printing. Leave the power turned ON
for a minimum of 30 minutes after printing.
• In the printing process, heat is used to fuse toner onto the page. As a result, it is normal for the machine to produce an odor dur-
ing and shortly after printing. Be sure to use this unit in an area with proper ventilation.
• Do not cover slots or openings on the unit. Inspect the air circulation vents regularly and remove any dust build-up with a vacuum
cleaner.
• If the inside of the unit is dirty, clean it with a soft and dry cloth (especially the lower glass).
• When replacing the toner cartridge or drum unit, do not allow dust, water, or liquids to come in contact with the drum. This may
affect print quality.
• Store unused paper in the original packaging, in a cool and dry place. Not doing so may affect print quality.
• Do not place the unit in an area where the paper tray may be obstructed (i.e., by a wall,etc.).
• Keep the air circulation vents away from walls etc.more than 50 mm (1 31 / ") to let the unit cool down.

2Warning
2.1. About Lead Free Solder (PbF: Pb free)
Note:
In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that con-
tains lead.
We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin, (Sn),
Silver, (Ag), and Copper, (Cu).
This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair
work we suggest using the same type of solder.
Caution
• PbF solder has a melting point that is 50°~ 70°F, (30°~ 40°C) higher than Pb solder. Please use a soldering iron with tempera-
ture control and adjust it to 700°± 20°F, (370°± 10°C).
• Exercise care while using higher temperature soldering irons.: Do not heat the PCB for too long time in order to prevent solder
splash or damage to the PCB.
• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F, ( 6 00°C).
• When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the
opposite side (See figure, below).
2.1.1. Suggested PbF Solder
There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper,
(Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufac-
turer’s specific instructions for the melting points of their products and any precautions for using their product with other
materials.
The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

2.2. Discarding of P. C. Board
When discarding P. C. Board, delete all personal information such as telephone directory and caller list or scrap P. C. Board.
2.3. Insulation Resistance Test
1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with an ohmmeter between the jumpered AC plug and each exposed metal cabinet part
(screw heads, control shafts, bottom frame, etc.).
Note: Some exposed parts may be isolated from the chassis by design. These will read infinity.
4. If the measurement is outside the specified limits, there is a possibility of a shock hazard.
2.4. Battery Caution
CAUTION
Danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the
manufacturer. Dispose of used batteries according to the manufacturer’s instructions.
The lithium battery is a critical component (type No.BR2032). Please observe for the proper polarity and exact location when
replacing it and the soldering the replacement lithium battery in.
2.5. Note for Repairing
Caution
Please inform users of the danger of data being lost at the time of repair.
Data will be lost in the following situations.
1. When replacing the ROM ass'y.
2. When replacing the Main board ass'y.
3. When executing mode #550 or #710.
There is a possibility of data loss in the following situations.
