MX-FNX4  OPERATIONAL DESCRIPTION  5 – 3
2. Feed/drive system
A. Outline
This machine comprises the finisher and the saddle stitch unit.
The finisher is designed to operate according to the commands
from its host machine to deliver arriving copies to trays in the
appropriate mode: simple stacking, job offset, or stapling. The sad-
dle stitch unit folds paper stack and delivers it to the delivery tray of
the saddle stitch unit after feeding, aligning, stitching, and feeding
the paper supplied from the host machine in accordance with the
commands received through the finisher controller PCB. Four deliv-
ery modes are available.
B. Control configuration of finisher
The finisher moves copies arriving from the host machine to the
delivery tray, stapling tray, or the saddle stitch unit according to the
mode of delivery. On the stapling tray, the copies are subjected to
job offset or stapling as instructed by the host machine.
In addition, stack is delivered from the stapling tray with the help of
the trailing edge assist guide as well as the delivery roller. The inlet
motor (FFM), delivery motor (FAM), and the trailing edge assist
motor (FASM) are the stepping motors. These motors are con-
trolled by the microprocessor (CPU) on the finisher controller PCB,
and rotate either clockwise or counterclockwise.
The paper paths are equipped with the following two sensors for
detection of paper (arrival, passage):
• Inlet sensor (FED)
• Feed path sensor (FPDD)
In addition, each delivery tray is equipped with a sensor designed
to detect the presence/absence of paper on it.
• No.1 tray paper sensor (FBED1)
• No.2 tray paper sensor (FBED2)
If a copy fails to reach or move past each sensor within a specific
period of time, the finisher controller PCB identifies the condition as
a jam, and stops the ongoing operation, and at the same time,
informs the host machine of the condition. When all doors are
closed after the paper jam is removed, the above two sensors (inlet
sensor and delivery path sensor) check whether or not copies are
being detected. If the sensors detect a copy, the finisher unit judges
that paper jams have not completely been removed, and sends the
paper jam removal signal to the host machine again.

C. Delivery path of finisher
Outline
Three types of delivery paths to the tray 1/2 of this machine are
available, depending on the processes of the paper delivery.
Straight delivery
If sort job is not to be implemented, all the paper is delivered
through the path shown in the figure below.
Path to stapling tray
If the sort job of paper in other than A4, B5, or LTR size or the sta-
ple sort is to be implemented, delivered paper passes through this
path. After paper is fed to the stapling tray, it is aligned and stapled.
Then, it is delivered with the help of the trailing edge assist.
Path to buffer/stapling tray
If the sort job of paper in A4, B5, or LTR size or the staple sort is to
be implemented, delivered paper passes through this path. After
two sheets (if stitching is to be performed at two points, two or three
sheets) are delivered to the buffer, they are aligned at the stapling
tray, stapled, and then discharged. Since paper is delivered from
the host machine continuously, paper fed to the buffer can be
simultaneously delivered together with stack paper that has been
already stapled at the stapling tray even while stapling or offset
operation is being carried out. Stack paper delivered from the buffer
is fed to the stapling tray, and paper stapled at the stapling tray is
fed to the tray.
If the sort job mode is selected, the simultaneous delivery of two
sheets of A4 size paper in paper stacks is described as shown
below.

MX-FNX4  OPERATIONAL DESCRIPTION  5 – 5
1) When the first paper reaches the switch back point, it is deliv-
ered to the buffer, and the trailing edge of it is held by the
buffer guide.
2) After the first paper is fed to the buffer, the second paper is
delivered from the host machine.
3) When the second paper reaches the switch back point, the first
delivery roller comes down, and delivers the first and second
sheets of paper to the stapling tray together with the delivery
roller. At this time, stack paper is fed to the delivery tray by the
return roller together with the trailing edge assist guide.
4) After stack paper in the stapling tray is fed to the delivery tray
and the trailing edges of the first and second sheets of paper
pass through the first delivery roller, the first and second
sheets are fed to the stapling tray by the stack delivery roller
and the return roller.
5)
The first and second sheets fed to the stapling tray are fed to
the delivery tray after alignment is complete.
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.
