Pulling the stapling tray extension [A] out by hand extends by 6 mm the distance that the
pawls must push the trailing edge of the stack. The extra 6 mm forces the edge of the stack
to bend more so it will snap down with more force and not catch on the end fence. This
prevents the trailing edge of the stack [B] from catching on the end fence when it falls into
the tray.
