OEP-3 V1 (UC)
3. Paper feed motor drive circuit
Motor drive circuit IC610 on the SE-539 board is controlled by the control signals at pins 99 and 100 of
IC5 (CPU) on the PRT-13 board. The motor is accelerated and decelerated by PWM control.
4. Tray motor drive circuit
Motor drive circuit IC607 on the SE-539 board is controlled by the control signals at pins 8 and 9 of IC5
(CPU) on the PRT-13 board. The motor is accelerated and decelerated proportionally to the reference
voltage at pin 6 of IC11 on the PRT-13 board.
