2.9 STACKING FOR BOOKLET STAPLING
2.9.1 OVERVIEW
There are two stoppers near the stapler unit. These stoppers hold the stack of paper in the
correct position during stacking.
The stoppers are called ‘stopper S’ and ‘stopper L’. Stopper S is used for legal size paper,
or shorter than 8.5 x 14 inches. Stopper L is used for paper that is longer than 8.5 x 14
inches.
 In corner stapling mode, the pawl on the stack feed-out belt holds the stack of
paper. For booklet stapling, this pawl stays at home position, which is on the rear
side, so it does not interfere with booklet stapling.
2.9.2 8.5 X 14 (LEGAL) OR SHORTER
At the start of the set, the upper retraction motor [A] turns on, and stopper S [B] moves
down into position to catch the paper
. The upper retraction motor also moves the upper
clamp roller [C] into contact with the stack
.
