2.5.4 Stack Tray Shift Motor Control

A rough diagram of the stack tray shift motor (M6) drive circuit is shown below.
The staple tray shift motor is a DC motor.
The motor rotation direction can be changed by the combination of motor drive signals sent
from the CPU (on the finisher controller PCB (IC1)) to the motor drive circuit.
If the stack tray lower limit sensor (PI10) has detected the tray, a restriction is placed on the
hardware so that the motor does not run in the direction that approaches this sensor.
