The stacking roller separation control separates the upper stacking roller from the lower stacking roller
to release the paper during the leading-end alignment and during the jogger operation. The staple
stacker driver drives the leading end alignment separation motor (M2102) to perform this control. The
stacking roller arm is attached to the upper stacking roller. As the motor (M2102) rotates, the upper
stacking roller lifts up and down together with the cam by the cam rotation.

The process for the stacking roller separation control includes the following:
1. Before the control begins, the upper and the lower stacking rollers pressurize the paper by the
spring.
2. The motor (M2102) rotation separates the stacking rollers.
3. The motor (M2102) makes the cam rotate to separate the stacking rollers.
