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.
2. The AC connector is connected properly. 3. Wrap the earth lead around the core 3 times. 4. Wrap the AC lead around the core 2 times (for KX-FM89BX). Wrap the AC lead around the core 3 times (for KX-FM89CX).
1.6. PERSONAL SAFETY PRECAUTIONS 1.6.1. 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.
1.7. SERVICE PRECAUTIONS 1.7.1. 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.

It may have a serious problem. The symptom: No response when the power is turned on. (No LCD display, and keys are not accepted.) The first step is to check the power source.
Page 87
Soldering faults difficult to detect with the naked eye are common, particularly for ASIC and RA (Resistor Array). But if you have an oscilloscope, you can easily determine the problem site or IC malfunction by checking the main signal lines. Even if you don’t have such a measuring instrument, by checking each main signal line and resoldering it, in many cases the problem will be resolved.
Page 88
As long as these signals remain normal, once the power is turned on, each IC can repeatedly output 5V (H) and 0V (L). The following shows NG and normal wave patterns. NG Wave pattern (Refer to NG EXAMPLE) Normal Wave Patterns...
Page 89
Remarks: When you use an oscilloscope to judge whether a signal to be tested is normal or NG, perform the signal check in exactly the same order as in [List 1]. (If the ASIC fails to access the ROM, the ASIC cannot access SRAM or DRAM normally.) The digital circuit actually operates according to the timing combinations of these signals.
Page 90
After the power is turned on, the ASIC initializes and checks each IC. The ROM, SRAM, and modem are checked. If initialization fails for the ICs , the system will not boot up. In this case, please find the cause as follows.

(The EIA standards specify the interface cable type (No. RS232C) and the voltage levels. If you use the TEST CONNECTOR, you can easily check the communication port without a PC. The connector should be wired so that the output signal can return to the input port.

The TEST CONNECTOR is provided as an option. Or you can get a connector available on the market and make the TEST CONNETOR as shown below.

This comes from our experience with experimental tests. For example: power supply and lightning surge voltage test, withstanding voltage test, intentional short circuit test, etc.
2.3.10.3. BROKEN PARTS REPAIR DETAILS (D101, D102, D103, D104) Check for a short-circuit in terminal 4. If D101, D102, D103 and D104 are short-circuits, F101 will melt (open). In this case, replace all of the parts (D101, D102, D103, D104, F101).

5. HOW TO REPLACE THE FLAT PACKAGE IC Even if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount), a soldering iron and a cutter knife, you can easily remove the ICs that have more than 100 pins.
Recommended power consumption is between 30 W to 40 W. / Temperature of Copper Rod 662 ± 50°F (350 ± 10°C) / (An expert may handle a 60~80 W iron, but a beginner might damage the foil by overheating.) - Flux / HI115 Specific gravity 0.863 / (Original flux should be replaced daily.) 5.2.
3. While the solder melts, remove it together with the IC pins. When you attach a new IC to the board, remove all solder left on the land with some tools like a soldering wire. If some solder is left at the joint on the board, the new IC will not be attached properly.
*Check the accuracy of the IC setting with the corresponding soldering foil. 2. Apply flux to all pins of the FLAT PACKAGE IC. 3. Solder the pins, sliding the soldering iron in the direction of the arrow. 5.4. BRIDGE MODIFICATION PROCEDURE 1.

6.3.9. SUPERVISION CIRCUIT FOR THE THERMAL HEAD TEMPERATURE 1. Function The thermistor changes the resistor according to the temperature and uses the thermistor's characteristics. The output of pin 169 of IC501 becomes a low level. Then when it becomes a high level, it triggers point A.
CROSS REFERENCE: THERMAL HEAD() 6.4. FACSIMILE SECTION 6.4.1. IMAGE DATA FLOW DURING FACSIMILE OPERATION COPY (Fine, Super-Fine, Half Tone) 1. Line information is read by CIS (to be used as the reference white level) via route 1, and is input to IC501. Refer to 6.4.2. Block Diagram.

6.4.3. THERMAL HEAD 1. Function This unit utilizes the state of the art thermal printer technology. The ink film is chemically processed. The ink film is comprised of two parts: an ink layer and a base film. When the thermalhead contacts this ink film, it emits heat momentarily, and the ink layer is melted and transferred to the paper.

/or diagrams appear, and the original document is reproduced. 2. Circuit Operation Refer to the block diagram and the timing chart on the following page. There are 9 driver ICs aligned horizontally on the thermal head and each one of these ICs can drive 192 heat-emitting registers. This means that one line is at a density of 192×9=1728 dots=(8 dots/mm).
Page 181
149 (THDAT) to the shift register of the ICs. The shift registers of the 9 ICs are connected in series, and upon the shift of the 1728 dot increment, the shift register becomes filled with data, and a latch pulse is emitted to each IC from IC501 pin 151 (THLAT). With this latch pulse, all the contents of the shift registers are latched to the latch registers.
6.4.4. SCANNING BLOCK The scanning block of this device consists of a control circuit and a contact image sensor made up of a celfoc lens array, an LED array, and photoelectric conversion elements. When an original document is inserted and the start button pressed, pin 20 of IC501 goes to a high level and the transistor Q512 turns on.This applies voltage to the LED array to light it.
Page 183
The stepping motor works for both transmission and reception. 2. Motor During motor driving, pin 163 of ASIC IC501 becomes a high level, and Q503, Q501 turns on. As a result, +24V is supplied to the motor coil. Stepping pulses are output from gate array IC501 pins, 157, 160~162, causing driver IC506 pins, 16~13 to drive the motor coil.
When the motor suspends while it is in the receive mode (about 70~80 msec), pin 163 of ASIC IC501 becomes a low level and Q503 turns off. Then Q501 also turns off, and instead of +24 V, + 5 V is supplied through D501 so that the motor is held in place. When the system is in the stand- by mode, all of the motor drive transistors turn off.
6.4.6.2. MODE OPERATION Once a mode is selected, the Drive Motor Gear rotates clockwise (CW) and then the controlling positions of Swing Gears A, B and C determine which gears convey their drive power in each mode. A. Transmit mode (See Fig. A.) : Swing Gear A engages Gear E and conveys its power to the Separation Roller Gear through Gear G and sets the Separation Roller for feeding documents.

Next Swing Gear A and B engages Gear E and Gear C respectively and conveys these power to the Separation Roller Gear and the Platen Roller Gear.
