The stack slide motor (M3) is a 2-phase stepping motor. This motor can rotate in only one direction due to the machine configuration. Movement of the stack slider

is controlled using the cam driven by the stack slide motor (M3). The motor driver controls operation of the stack slide motor (M3) with the pulse signals (A, A*,

B, B*) output in response to the signal from the CPU.

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.
