Paper stack height detection
Stack height detection is done each time a sheet is added to the paper stack.
The stack height actuator presses on top of the paper stack. The sensor (stack height) detects if the stack
thickness has reached the limit. Limiting the thickness of the stack prevents damage to the staple unit.
The motor (stack height) drives the actuator.
