4:
The jogger fences remain 1 mm away from the sides of the stack. The feed out belt [1]
raises the stack until the top of the stack is 10 mm past the leading edge pressure roller [2]
and stops. The leading edge pressure roller descends and applies pressure to the top of the
stack. The stack junction gate [3] (normally open) closes. The pressure roller [4] and
pressure plate [5] retract.
5:
The feed out belt [6], transport rollers [7], [8], and clamp rollers [9] rotate and feed the stack
past the closed stack junction, over the top and down toward the bottom fence [10]. At the
same time, the fold unit bottom fence descends from its home position and stops 10 mm
below the fold position.
6:
The rollers feed the leading edge of the stack to within 3 mm of the stack stopper of the
bottom fence [13]. The fold unit entrance sensor [11] detects the stack and opens the clamp
rollers [12]. The stack drops 3 mm onto the fold unit bottom fence [13]. At this time, the first
sheet [14] of the next stack feeds to the stapling tray.
