2.3 PRE-STACKING
This example describes what happens to Set 2 during the feed and stapling cycle of sets that
contain three pages.
[A]: While the Set 1 is being stapled in the staple tray [1], the 1st sheet of Set 2 [2] feeds to the
pre-stack tray, and the 2nd sheet of Set 2 [3] enters the finisher.
[B]: The pre-stack junction gate opens and the 1st sheet of Set 2 [4] switches back to the top
of the pre-stack tray as the 2nd sheet of Set 2 [5] starts to descend.
[C]: As the 2nd sheet of Set 2 continues to descend, the 1st sheet of Set 2 is fed from the
pre-stack tray. At this time the leading edges [6] of both sheets are even.
[D]: The trailing edges of the 1st and 2nd sheets of Set 2 pass the junction gate [7] as the 3rd
sheet of Set 2 [8] enters the finisher.
