NOTE The staple stacker driver rotates the motor (M2102) and performs the detection, even
when the upper stacking roller is already at the separated position.
Paper pile alignment control
This sequential control aligns the leading-end of each paper. The staple stacker driver PCA controls the
leading-end alignment separation motor (M2102) and rotates the leading end alignment roller.

Figure 4-58 Paper pile alignment control
The leading-end alignment roller changes its shape easily because the inside is hollow. This feature
enables the paper to be touched with wider contacting surface at the leading-end alignment control and
improves the alignment performance.
1. Before the operation, the leading-end alignment roller stays at the waiting position.
