2) Structure of recording mechanism
Recording is achieved by applying a suitable pressure to the thermal head through the imaging film of the recording paper feed roller and the recording paper. The main scanning is electronically done, and the sub-scanning is mechanically done (by sending the recording paper with the recording paper feed roller).
The following items are described as the simplified checking method. Are the power and signal cables of the thermal head suitably treated? Does the same symptom appear even if the thermal head pressure spring is replaced? Is the feed roller of the recording paper concentric? (Density is uneven at intervals.) Does the same symptom appear even if the thermal head is replaced? Is the imaging film stained or wrinkled?

External telephone hook status detection circuit (HS1)
This circuit comprises the photo-coupler PC1, resistors R3 and R4, Zener diodes ZD1 and ZD2. When an external telephone is connected and enters the on-hook mode, the LED of photo-coupler PC1 emits light and the light receiving element turns on. The status signal HS1 is input to the pin 84 of (XFCR-MVP) (IC4: control PWB). HS1 LOW: EXT. TEL OFF-HOOK HS1 HIGH: EXT. TEL ON-HOOK 3. Dial pulse generation circuit The pulse dial generation circuit comprises the CML relay. 4. CML relay The CML relay switches over connection to the matching transformer T1 while the FAX or built-in telephone is being used. 5. Matching transformer The matching transformer performs electrical insulation from the telephone line and impedance matching for transmitting the TEL/FAX signal. 6.

PHOTO COUPLER

Fig. 8 The power unit intakes input of AC 120V, 50/60 Hz and supplies output of +24V, +7.4V and +5V as shown in the block diagram. (See Fig. 8.) Moreover, the frequency is varied depending on the load of the output. As the load becomes the heavier, the frequency becomes the smaller to extend the ON period. The constant voltage is controlled by applying the feedback to the control circuit through the photo coupler PC1 from +24V output. The overcurrent-protective circuit detects that the ON period becomes the wider as the output load becomes the heavier. For the control, the OFF period is extended by the control circuit to squeeze the energy which is accumulated in the primary winding of the transformer T1. For protection against overvoltage, the rise of the output voltage of +24V on the secondary side is brought into the overcurrent state through the continuity of the power zener diode D104 between +24V output and GND. Thus, the overcurrent-protective circuit of the control circuit is activated for the protection.
2-1. Filter, rectifying and smoothening circuit
In the filter section, the noise generated from the power unit is eliminated from being discharged to the external, and external noise is prevented from entering. Thunder or other excessive surge is prevented by the varistor Z1. In the rectifying and smoothening section, AC input is rectified by the diodes D10, 11, 12 and 13, and is smoothened by the capacitor C5. Thus, DC voltage is supplied to the switching section. Moreover, the thermistor NTC1 prevents surge current when the power is turned on.

2-2. Switching section

The circuit uses the ringing choke converter of a self-excited type. Since MOS. FETQ1 is repeatedly turned on and off in this system, the DC voltage supplied from the rectifying and smoothening section is converted into the high frequency pulses. While Q1 is on, energy is accumulated in the primary winding of the transformer T1, and while Q1 is off, energy is discharged to the secondary side. Thus, the power is supplied.

2-3. +24V circuit

Output is supplied by rectifying and smoothening the output of the transformer T1 with the diode D101 and capacitor C101.

2-4. +5V circuit

+5 V output is generated by rectifying and smoothening the output of the transformer T1 with the diode D102 and capacitor C102 and stabilizing it with the 3-terminal regulator IC103.
