Transistor array which consists of seven transistors
5
-1: Transistors that control the rotation direction of the motor according to the MM4
through MM1 signals.
5
-2: Transistor that turns on and off the solenoid.
The combination of the solenoid state and the motor rotation direction deter-
mines to which the motor torque should be transmitted, the cutter, the document
feeding mechanism, or the paper feeding mechanism.
5
-3: Transistor that turns on and off the CR1 relay for switching on and off the +26V
power source to the thermal recording head.
5
-4: Transistor that turns on and off the CML relay.
6
Document front and rear sensor circuitry that is active only while the SEON signal is on.
The LEDs for the sensors are driven by the +26V source.
6
-1: PH2, document rear sensor
6
-2: PH1, document front sensor
