Figure 5-24 Staple-mode feed and delivery diagram (2 of 6)
At a specific time after the paper-inlet sensor (PS1101) detects the leading edge of the media, the
stapler/stacker PCA changes the speed of the feed motor (M1103) to synchronize the feed rollers
with the speeds of the other stapler/stacker motors and rollers. The stapler/stacker PCA then
activates the paddle motor (M1101) counterclockwise to again disengage the upper and lower
delivery rollers. The delivery deflector returns to its normal position.

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.
