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 lead-
ing 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 sen-
sor [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.

The bottom fence [1] raises the stack to the prescribed fold position
[2].
8
The fold plate [3] moves to the left and advances 1/3 its maximum
horizontal stroke and exerts 20 kg (44 lb.) of pressure at the fold
rollers [4].
9
With the fold plate pushing the stack into nip of the fold rollers [5],
the fold rollers begin to rotate and fold the stack as it feeds out.

With the fold plate pushing the stack into nip of the fold rollers [5],
the fold rollers begin to rotate and fold the stack as it feeds out.
10
When the fold rollers [1] feed the stack 10 mm past the nip, the fold
plate retracts until it no longer touches the stack. The fold unit exit
sensor [2] detects the folded edge of the stack and stops the fold
rollers.
11
The rotation of the fold rollers [4] reverses and feeds the folded
edge back until only 3 mm of the fold [5] remains at the nip.
12
The fold rollers [6] rotate forward once again feed out. The fold unit
exit sensor [7] once again detects the edge of the fold.

The fold rollers [6] rotate forward once again feed out. The fold unit
exit sensor [7] once again detects the edge of the fold.
13
With the feed of the stack halted, the fold plate [1] retracts. The fold
plate HP sensor (not shown) detects the fold plate and stops it at its
home position.
14
The fold rollers [2] and fold unit exit rollers [3] begin to rotate
together and feed out the folded booklet to the booklet output tray.
15
Once the trailing edge of the stack passes the fold unit exit sensor
[4], the clamp rollers [5] close to be ready to feed the next stack.
The fold unit bottom fence [6] descends. The bottom fence HP sen-
sor [7] stops the bottom fence when it detects the actuator on the
bottom fence.
