Page 109 (4) Heater lamp control circuit General The heater lamp control circuit detects the heat roller surface temperature with the thermistor, converts it into voltage level, and outputs it to the CPU analog input pin. The CPU converts the analog voltage into digital signal level, com- pares it with the value set by simulations, turns on/off the heater lamp according to the level, and maintain the heat roller surface tempera- ture at a constant level.

The output, therefore, is delivered to A: Stepping motor phase A coil drive signal the load through the driver IC.

Page 112 (10) Copy lamp control section The change in the copy lamp exposure level is adjusted by changing the ON period duty of the output pulse (CLPUM) from the CPU and controlling the copy lamp voltage. Fig. 1 and Fig. 2 show the circuit diagram and the waveform.
Page 113 The relationship between the CLV and the pulse ON period is as shown in the figure below: CPU output (CLPWM) 8 or 10 msec Pulse ON (Changeing) 60Hz 50Hz Pluse ON period (msec) • When the pulse ON period is shorter, the CLV becomes higher, and vice versa.
Page 114 4. Operating section (1) Outline The operating circuit is composed of the key matrix circuit and the display matrix circuit. Key detection: Keys are detected with signal matrix of W0 (Q25) ∼ W7 (Q32) and KEY0 ∼ KEY2. With W0 signal at LOW (GND) and W1 ∼ W7 at HIGH (open), the level of KEY0 ∼...
