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.
W e 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 solderin g iron with
temperature control and adjust it to 700° ± 20° F, (370° ± 10°C). In case of using high temperature solderin g 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 applyin g the Pb solder.
·
W hen applyin g 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. W hile 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 followin g 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 P.C.Boards marked as “PbF” use Pb Free solder. (See the figure below.) Pb Free is not used the Power Supply Board of this unit. (Example:Dig ital board) R664 54C672 C675 R680 IC608 IC606 IC610 RA623 RA608 RA607 C699 C698 C680 C6 5 C681 R751 R750 R749 RA613 RA6 C682 R676 C693 24 25 48 1 RA605 RA606 RA622 R674 RA625 RA624 RA614 1 CN610 15 R688+3.3V C771 Q614 L639 D603 Q613 R733 L643 R637 Q626 Q627 R638 R634 R633 F603 Q604 R618 R610 R611 Q608 CN606 CN603 RA617 R624 R623 Q609Q622 Q623 Q624 Q625 R625 1 2 CN609D604 F604 CN612 CN613 CN605 C604 Q610 D608 R723 C752 C740 8 1 4 511 1 14 1Q615R690 F605 C753 C626 L678C705 S I I R613 C602 R606 41 80 81 40 603 778 PbF Marked(Digital Board : Component View) Note: The“PbF” marked may be found on differen t areas of the same P.C.Board,dep ending on manufacture date. 5 KX-FLB75 8RU Downloaded From ManualsPrinter.com Manuals

1.4. SAFETY PRECAUTIONS 1. Before servicing, unplug the AC power cord to prevent an electric shock. 2. W hen replacin g parts, use only the manufacturer´s recommended components. 3. Check the conditio n 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 followin g insulation resistance test to prevent the customer from being expose d 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 expose d metal cabinet part (screw heads, control shafts, bottom frame, etc.). Note: Some expose d parts may be isolated from the chassis by design. These will read infinity. 4. If the measurement is outside the specifie d limits, there is a possibility of a shock hazard. 1.6. FOR SERVICE TECHNICIANS ICs and LSIs are vulnera ble to static electricity. When repairing, the following precautions will help preven t recurring malfunctions. 1. Cover the plastic part ´s boxes with aluminum foil. 2. Ground the solderin g 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 explosi on 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 replacin g and solderin g the replacement battery . 8 KX-FLB75 8RU Downloaded From ManualsPrinter.com Manuals
1.8. AC CAUTION For safety, before closing the lower cabinet, please make sure of the followin g precautions. 1. The earth lead is fixed with the screw. 2. The AC connector is connected properly. 3. W ind the earth lead around the core 5 times. 4. W ind 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, especia lly when the unit is operating. 9 KX-FLB75 8RU Downloaded From ManualsPrinter.com Manuals
1.9.2. LIVE ELECTRICAL SECTIONS
All the electrical sections of the unit supplie d 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 supplie d to the primary side of the power supply unit. Therefo re, always unplug the AC power cord before
disassembling for service.
1.9.3. LASER BEAM AND FUSER UNIT SECTION
