Remarks: Regarding the reception problem, we have investigated the conceivable causes in the flow chart except for the software- related errors.
  • Page 75 KX-FP101 4. The unit can copy, but cannot transmit/receive. 5. The unit can copy, but cannot either transmit/receive long distance or international communications. The following two causes can be considered for this symptom. Cause 1: The other party is executing automatic dialing, the call has been received by this unit, and the CED or DIS signal response time is too long.
  • Page 76 KX-FP101 Cause 2: Erroneous detection because of an echo or an echo canceler. The sea bottom cable or satellite communication path (4 Line Type) (Echo/Echo Canceler) The signal from FAX1 reaches FAX2 via stations 1 and 2, but the reflection signal at station 2 also returns via station 1 (echo). As the distance between station 1 and station 2 is far, the echo returns to FAX 1 at a max of 600 msec after transmission.
  • Page 77 KX-FP101 (Cause C) This model is FAX1 and the other party is FAX2. For transmission from this model to FAX2, FAX2 executes automatic reception and transmits a CED signal (2100 Hz) followed by a DIS signal. As the echo cancelers stops as described in cause B, the echo of the DIS signal returns to FAX2. On the other hand, this model detects the DIS signal and transmits a DCS signal.

  • Page 91: Digital Board Section

    KX-FP101 2.3.3.4. Digital Board Section When the unit fails to boot up the system, take the troubleshooting procedures very carefully. 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 92 KX-FP101 2.3.3.4.1. Digital Block Diagram...
  • Page 93 KX-FP101 You also need to check the signal lines listed here [List 1] when the unit fails to boot up the system. Those signal lines should remain normal. Other signal lines are not directly related to that failure even if they have faults or troubles. As long as these signals remain normal, once the power is turned on, each IC can repeatedly output 5V (H) and 0V (L).
  • Page 94 KX-FP101 Normal Wave Patterns 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.

Circuit Operation The reception signal output from the line transformer T101 is input to pin (6) of IC101 via C126 and R131, and then the signal is amplified at pin (7) of IC101 and sent to the reception system at 11.6dB. The transmission signal goes through C131 and R137 and enters IC101-pin (2), where the signal is amplified to about 7.4dB.

    KX-FP101 6.13. POWER SUPPLY BOARD SECTION This power supply board uses the switching regulator method. [Input Circuit] The input current goes into the input rectifier circuit through the filter circuit. The filter circuit decreases the noise voltage and the noise electric field strength. [Rectifier Circuit] The input current is rectified by D101,D102,D103 and D104 and charges C106 to make DC voltage.
  • Page 200 KX-FP101 The following is an overview of how the power supply unit is controlled. The control method of this power supply unit is pulse width modulation. When Q is ON, the energy is charged in the transfer primary coil according to E .
  • Page 201 KX-FP101 [Surge Absorber Circuit] This circuit is for absorbing surge voltage generated by the transformer. [Control Circuit and Detecting Circuit] The control circuit amplifies the output with increased voltage detected in the error detecting circuit. Then it drives the main transistor.
