1 INTRODUCTION
1.1. 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
contains 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 although, with some precautions, standard Pb solder can also be used.
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
temperature control and adjust it to 700° ± 20° F, (370° ± 10°C). In case of using high temperature soldering iron, please
be careful not to heat too long.
· PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100°F, (600°C).
· If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible
and be sure that any remaining is melted prior to applying the Pb solder.
· 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).
1.1.1. 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.

1.2. HOW TO RECOGNISE THAT Pb FREE SOLDER IS USED

KX-FLB758RU

1.4. SAFETY PRECAUTIONS
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.
1.5. 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.
1.6. FOR SERVICE TECHNICIANS
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.
1.7. BATTERY CAUTION
CAUTION
There is a danger of explosion if the battery is incorrectly replaced. Replace only with the same or equivalent type
recommended by the manufacturer. Dispose used batteries according to the manufacturer’s instructions:
The lithium battery is a critical component (type No. CR2032). Please observe for the proper polarity and exact location when
replacing and soldering the replacement battery .

KX-FLB758RU

1.8. AC CAUTION
For safety, before closing the lower cabinet, please make sure of the following precautions.
1.The earth lead is fixed with the screw.
2.The AC connector is connected properly.
3.Wind the earth lead around the core 5 times.
4.Wind the earth AC around the core 4 times.
1.9. PERSONAL SAFETY PRECAUTIONS
1.9.1. 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.

KX-FLB758RU

1.9.2. 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
disassembling for service.
1.9.3. LASER BEAM AND FUSER UNIT SECTION
· The printer of this unit utilises 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.

KX-FLB758RU

1.10. SERVICE PRECAUTIONS
1.10.1. 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.
To prevent static electricity damage to the interface connectors (parallel and USB) or other electrical components inside the unit,
touch a grounded metal surface, such as the metal part under the parallel interface connector before touching the components.
