(4) The second and subsequent sets of paper are conveyed and stacked.
1) The first page stops in the stack er entrance with the by-pass gate opened. The stack er entrance roller stops
to wait for the previous stack to be exited.
2) The by-pass gate is closed and the second page is stacked on top of the first.
3) Once the previous stack has exited, the stack entrance roller rotates and the first and second pages are
simultaneously sent to the stacker.
* The above steps (1) to (3) are for paper to a maximum of A4 size.
4) The stacker section roller sends the paper to the flat-stapling stopper and the paper is lined up in the
lengthwise direction.
5) The upper alignment plate lines up paper in the widthwise direction.
6) When all paper is conveyed to the stacker, the paper is stapled.
7) The second and subsequent sets are conveyed by the paper exit arm and the paper is exited to the main
tray.

[2] Mechanisms
1. Paper Conveyance
Paper conveyance is carried out by conveyance rollers A,
B, C, and D; the intermediate conveyance roller; the conveyance slide shaft; and sub-tray paper exit rollers A, B,
and C. These components are driven b y M1 (FNS conv eyance) by means of a timing belt.
Stacking is implemented by the stacker entrance roller and
the swivel roller. These rollers are driven by the M13
(stacker entrance) by means of a timing belt.
Ejection to the main tray (following staple processing) is
implemented by the stacker paper exit belt arm and the
paper exit roller. These components are driven by the M7
(paper exit).
Ejection to the booklet tray is implemented by the folding
convey ance roller, the folding conve yance belt, the f olding
knife, f olding rollers A and B, and pressure rollers A and B.
The folding knife is driven by M19 (folding knife). The conveyance belt, folding rollers, and pressure rollers are driven
by the M20 (folding conveyance) by means of a timing
belt.
2. Paper Path Switching
Gate
Sub-tray Gate
SD2
(Sub-tray Paper Exit)
By-pass Gate
SD5 (By-pass)
SD1 (Gate)
Path switching is carried out b y the gate, the sub-tray gate ,
and the by-pass gate. Each of these is controlled by the
ON/OFF action of a corresponding solenoid: SD1 (gate),
SD2 (sub-tray paper exit), and SD5 (b y-pass), respectively .
3. Shift Unit Sort Shift Operation
(1) Paper entering the shift unit is fed toward the
paper exit direction by the action of the slide
shaft.
(2) Driving by M2 (roller shift) causes the linkage to
shift the slide shaft and paper 30mm toward the
rear.

Paper Alignment (Staple Mode (Flat Stapling))
Sheets conveyed into the stacker are aligned by the oscillation of the (front and rear) alignment plates/upper. The
alignment plates/upper are driven by M5 (alignment plate/
upper).
Paper Alignment (Booklet Mode (FS-108BM only))
Sheets conveyed into the stacker are aligned by the movement of the (front and rear) alignment plates/upper and
the (front and rear) alignment plates/lower . The alignment
plates/upper are driven by M5 (alignment plate/upper); the
alignment plates/lower are driven by M15 (alignment plate/
lower). The stapling-and-folding stopper is moved b y M14
(stapling-and-folding stopper) and is released by M17 (stapling-and-folding stopper release).
Paper Exiting
Stapled paper is sent to the paper exit by the paper exit
arm. The paper exit belt is driven b y M7 ( paper exit-roller).
Feeding to the Folding Unit (FS-108BM only)
M17 (stapling-and-folding stopper release) releases the
stapling-and-folding stopper and feeds the paper into the
folding unit.

Paper Sizes A4R and Above
Because paper of this size juts out from the stacker, the
paper exit opening is held open from the start of copying
until the completion of stapling.
c. Pressure of the Paper Exit Roller
The paper exit roller turns more slowly than the conveyance rollers (A, B, C, and D), and remains unengaged by
the nip roller except during ejection.
When paper reaches the paper exit opening, the paper
exit roller is engaged by the nip roller and the paper is
ejected to the main tray. Engagement and release is controlled by SD4 (paper exit opening).
b. Paper Exit of the Staple Mode (Flat Stapling)
Upon completion of stapling, the paperr exit closes, and
the paper is grasped and ejected to the main tray. The
opening and closing of the paper exit is controlled by M8
(paper exit opening).
