4. As the cam rotates, the stacking roller arm is pushed up, and the upper stacking roller is pulled up
from the paper.

5. When the stacking rollers are engaged, the stacking roller arm is released by further cam rotation.
This causes the stacking roller arm to lower. Then, the upper stacking roller touches the paper.
NOTE The swing separation sensor detects the position of the stacking roller arm.

NOTE The stacking roller control is also performed when the power switch is turned ON
and at the start of the paper feed operation.
Stacking roller separation detection
The staple stacker detects the position of the upper stacking roller for operating the stacking roller
separation control. This detection is performed by the staple stacker driver that is monitoring the SWING
SEPARATION (SWNG_SNS) signal from the swing separation sensor (SR2105). There is a sensor flag
moving together with the separation cam. When the stacking rollers are separated, the flag interrupts
the sensor (SR2105). This brings the staple stacker driver determines that the stacking rollers are
separated. Conversely, when the rollers are engaged, the flag does not interrupt the SR2105. This brings
the driver determines that the rollers are engaged. During the stacking roller separation detection, the
staple stacker driver rotates the leading-end alignment separation motor (M2102) for a specified period
of time. If the SWNG_SNS signal does not change, the driver determines failure of the leading-end
alignment separation motor, stops the loads, and notifies the formatter.
