At a specific time after the paper inlet sensor (PS1101) detects the trailing edge of the media, the stapler/stacker driver PCA activates the clamp solenoid (SL1102). The clamp keeps the page from being pushed out of position by the pages that follow.

The stapler/stacker now operates according to the following conditions.

●Is this the last page in the staple job

•No. The feed motor (M1101) changes speed and another page enters the stapler/ stacker. The stapler/stacker driver PCA activates the jogger motor and the jogger guide moves to align the media stack horizontally. The stapler/stacker driver PCA activates the paddle motor and the paddle pushes the page up against a guide to align the media stack vertically. The delivery deflector moves into position to allow the next page to enter the stapler/stacker.

•Yes. The feed motor (M1101) turns off. The stapler/stacker driver PCA activates the jogger motor and the jogger guides move inward to align the media stack horizontally. The stapler/stacker driver PCA activates the paddle motor and the paddle pushes the page up against a guide to align the media stack vertically. Then the pages are stapled.
