Stapler/stacker feed and delivery The stapler/stacker feed and delivery system consists of several feed rollers and guides that are driven by the stapler/stacker motors and solenoids. Sensors along the stapler/stacker paper path detect the arrival and passage of media and confirm the position of the jogger guide. The jogger guide helps to align the pages before stapling and dropping them into the delivery bin. The stapler/stacker has two modes. The staple mode staples media together and drops them into the delivery bin. The stack mode drops the media directly into the delivery bin without stapling them together. Table 35.
