D. Control configuration of saddle stitch unit
(MX-FNX4)
The paper output mechanism serves to keep a stack of sheets
coming from the finisher in the paper path for the next steps (sta-
pling, folding).
The paper inlet is equipped with the No.1 deflector plate and the
No.2 deflector plate, which operate to configure the paper path to
suit the size of paper. The paper positioning plate is kept in wait at a
predetermined location to suit the size of paper. The paper position-
ing plate is driven by the paper positioning plate motor (FPPM), and
the position of the plate is identified in reference to the number of
motor pulses coming from the paper positioning plate home posi-
tion sensor (FSPPHPD). A sheet moved by the inlet roller is han-
dled by the feed rollers and the crescent roller and held in a
predetermined position. The feed roller serves to move sheets by
coming into contact with or moving away from sheets as needed.
The alignment plates put the stack into order each time a sheet is
output. The alignment plates are driven by the alignment motor
(FSJM), whose position is identified in reference to the number of
motor pulses coming from the alignment plate home position sen-
sor (FSAHPD).
To prevent interference between paper and the paper folding rollers
when the paper is being output, the folding rollers are designed to
be covered by a guide plate. The guide plate moves down before
paper is folded so as to expose the paper folding rollers.
The inlet is equipped with the No.1, No.2 and No.3 paper sensors
(FS1PD, FS2PD, FS3PD) each suited to a specific paper size, and
the paper positioning plate is equipped with a paper positioning
plate paper sensor (FSPPPD).

E. Delivery path of saddle stitch unit (MX-FNX4)
The paper fed from the host machine is led into the finisher, and
delivered to the saddle stitch unit by the saddle stitch flapper. Thus,
the saddle stitch unit performs stitch and saddle operations on
paper, and delivers it to the saddle stitch delivery tray.

F. Basic operation of saddle stitch unit (MX-
FNX4)
Feeding of paper
Paper fed from the finisher is stored into the paper path in virtually
vertical direction sequentially. The paper path is determined by the
operation of the two paper deflector plates depending on the size of
paper.
The storage location of paper is determined by the paper position-
ing plate so that the center of paper is aligned with the stitching and
folding positions.
The order of paper storage is as follows; the last fed paper is stored
in the delivery direction of the previously fed paper. Number of
sheets allowed to be stored is as shown below.
• 15 sheets (Max.: 14 sheets of 80g/m

Alignment
Whenever paper is stored into the vertical path, the alignment plate
equipped at the edge of the vertical path aligns paper. Furthermore,
it also carries out folding of paper stack and alignment before deliv-
ery.

it also carries out folding of paper stack and alignment before deliv-
ery.
Stitching
After all the paper is stored, the two stitch units located at the cen-
ter of the paper stitch the paper sequentially.
The two stitch units cannot be operated simultaneously so as to
prevent wrinkling of paper that may occur between the stitches and
to limit the load applied to the power supply.
If only one sheet of paper is fed from the copier, the next step, mov-
ing of stacks is started without stitching.

Feeding of Stacks
The stitched paper is fed to the folding and delivery positions. The
paper folding must be performed at the point that the center of
paper (stitched point) is aligned with the height of the paper push-
ing plate and the folding roller pressurizing section.
The stack is moved forward by operating the paper positioning
plate. When the plate is operated, the guide plate that has been
covering the paper folding rollers, also moves down so that the
paper folding rollers directly face the stack.

Folding/Delivery
The paper pushing plate pushes against the center of the stack to
move it in the direction of the paper folding rollers. In response, the
paper folding rollers pick the stack along its center and fold it in two.
The paper folding rollers together with the delivery roller then move
the stack along to output it on the delivery tray.
