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.
• [E]: The 1st and 2nd sheets of Set 2 [9] switch back together into the top of the pre-stack and wait for
the 3rd of Set 2 sheet to arrive.
• [F]: The stapling of Set 1 in the staple tray [10] is completed.
• [G]: Set 1 [11] exits the staple tray.
