FAX 1 S1

Station 1

Station 2

2 Line Type A sea bottom cable or satellite communication path. (4 Line Type)

2 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 600msec after transmission. So, there is a possibility that this signal is detected as the signal from FAX 2. For a normal call, there is also a possibility that their own voice echo will make the call difficult to perceive. For this reason, each station (station 1, station 2) attaches echo cancelers (S1, S2) for international lines or long distance lines. For the echo canceler, the level of the transmission signal from FAX 1 is compared with the level of the reception signal from FAX 2, and when the transmission signal is larger, S1 is closed, while S2 is opened when it is smaller. In other words, when there is transmission from FAX 1, S1 is closed and S2 is open so that the echo does not return to FAX 1.

| 42 |

(Cause and Countermeasure) (Cause A) When the training signal is transmitted from FAX1 during the communication procedure at the time of transmission from FAX1 to FAX2, there is a delay until the echo canceler operates and S1 is closed. Therefore, a part of the head of the training signal may drop out and normal reception by FAX2 may not be possible, and transmission may not be started. (Countermeasure A) When the international line mode becomes ON in the service mode (code No. 521), a dummy signal is attached to the head of the training signal to prevent this problem. As this normally is ON, it is necessary to reconfirm that this has not become OFF. When the international mode is switched to OFF, the transmission side will try the training signal three times at each speed (9600BPS, 4800BPS and 2400BPS). When it is NG, it will drop the speed by one rank (fall-back). When the international mode is switched to ON, each speed will be tried only twice. In other words, the slower speed with fewer errors is reached more easily. This is done as line conditions may deteriorate and the picture may be affected more during communication with international lines or long distance communication, even when the training has been OK. The default value is ON as preference is given to clearer pictures rather than speed. (Cause B) The echo canceler operation is stopped by a signal of 2100Hz (i.e. S1 and S2 become ON). Accordingly, when FAX1 has executed automatic reception, a CED signal is output, and if this signal is 2100Hz, S1 and S2 will become ON. Then the echo of the DIS signal output afterwards may be received and FAX1 may execute an erroneous operation, preventing communication from starting. (Countermeasure B) In the service mode, the CED signal frequency is set to 1100 Hz (code No.520) or the time setting between the CED signal and the DIS signal is set from 75msec to 500msec (code No.593). This is done because the echo canceler operation stop mode is cancelled by an interval of 250msec or more. (Cause C) The KX-FT57E shall be assumed as FAX1 and a different company's set shall be assumed as FAX2. For transmission from the KX-FT57E to FAX2, FAX2 executes automatic reception and transmits a CED signal (2100 Hz) followed by a DIS signal. As the echo cancelers here stop as described in cause B, the echo of the DIS signal returns to FAX 2. On the other hand, the KX-FT57E detects the DIS signal and transmits a DCS signal. In other words, it is possible that the echo of the DIS signal and the DCS signal transmitted from the KX-FT57E reach FAX 2 one after the other, FAX 2 executes erroneous detection, and communication is not started. (Countermeasure C) When the international DIS detection setting is made effective in the service mode (code No.594), the KX-FT57E does not respond to the first DIS signal and returns a DCS signal only for the second DIS signal. In other words, there is a 250msec interval between the transmission of the first and second DIS signal. So, the echo cancelers operation recovers and no echo is generated for the second DIS signal. Note: When the other FAX does not respond with a DCS signal after DIS signal transmission, the DIS signal is transmitted three times.

(5) CHECK THE WAVE FORM This check requires a 4 channel digital storage oscilloscope higher than 400 MHz.
Are there any wave forms on the line? (AD, D0, ROMCE, RD)
Check the power line, oscillation (12 MHz), and RESET again.
If there is still no reaction, replace the ASIC and check again.
Refer to page 65. YES The address to SRAM or the MODEM may have been unsuccessful. (Refer to pages 67~69.)
Do the wave forms on A0, D0, ROMCE, and RD seem OK?
Refer to page 66. Is the active term of ROMCE longer than normal? YES YES The watch dog error frequently activates RESET because the address or data is confused with a problem on the address or data bus.
Does RESET come frequently? (every 4 msec)

RESET is no problem.

Check the operation panel I/F. Check that the lines connect CN5 from ASIC (IC1). If there is no problem on the lines, replace the ASIC (IC1).
The address to the SRAM or MODEM may have been unsuccessful.
Check the bus line for: short circuit opening voltage

Refer to pages 67~69.

Let's observe the wave form in order to fix the defective IC. Please observe A0, D0, ROMCE, and RD by using a digital oscilloscope. The graphs below show you a wave form that is observed when the unit (board) is working correctly. Both graphs are good waves. Wave forms change rapidly (like the graphs below).

The graphs below show you wave forms that are observed when the unit (board) doesn't work. (A3 is intentionally opened at pin 135 of ASIC on this board.) Please check that the active (low level) term of ROMCE is longer than the good wave form. ROMCE is active (low level) except RESET is active and comes every 4 msec. For these wave forms, ASIC (IC1), ROM (IC2) or the bus line route are possibly defective. When soldering, conductance is no problem and you need to replace these ICs.

(1) Function This unit utilizes state of the art thermal printer technology. The recording paper (roll paper) is chemically processed. When the thermal head contacts this paper it emits heat momentarily, and black dots (appearing almost as points) are printed on the paper.
COMPOSITION OF THE RECEIVE RECORDING SECTION (THERMAL RECORDING FORMAT)
Transportwalze Thermal Recording Paper

Thermokopf

(2) Circuit Operation There are 18 driver ICs aligned horizontally on the thermal head and each one of these ICs can drive 96 heat emitting registers. This means that one line is at a density of 96 ~18=1728 dots=(8 dots/mm). White/Black (white=0, black=1) data in one line increments is synchronized at IC1 pin 24 (THCLK) and sent from IC1 pin 22 (THDAT) to the shift register of the ICs. The shift registers of the 18 ICs are connected in a series, and upon shifting of the 1728 dot increment, all the shift register becomes filled with data and a latch pulse is emitted to each IC from IC1 pin 23 (THLAT). With this latch pulse, all of the contents of the shift registers are latched to the latch registers. Thereafter, through the addition of a strobe from the IC1 pins (25, 26, 27, 28), only the dot location of black (=1) among latched data activates the driver and a current passes to a heat emitting body to cause heat emission. Here the strobe of the four lines STB1 to STB4 impresses at intervals of 9.216 msec, as required for one-line printout, for each 1/4th of the 18 IC units (4 units or 5 units) at each time interval divided into four equal increments. The sequence is as shown the timing chart (Next page). [Moreover, for strobe width, the resistance value of the thermistor inside the thermal head is constantly detected by IC1 pin 38, and values from the ROM (IC2) table corresponding to the temperatures eliminate density temperature changes through the setting in the CPU.] When the thermal head is not used, the IC1 (119, TH-POWER) becomes low, IC7 becomes OFF, RL201 breaks, and the +24 V power supply for the thermal head driver is not impressed to protect the IC.
