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.
Pre-Stacking
[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.

[H]: The three sheets of Set 2 [12] feed together into the stapler tray for stapling. Pre-stacking is only done for A4, B5, and LT paper.
In one-staple mode, one sheet goes to the pre-stacking tray. Then two sheets go to the stapler tray at the same time.
In two-staple mode and booklet mode, three sheets go to the pre-stacking tray. Then four sheets go to the stapler tray at the same time.
