[3] OPERATIONAL DESCRIPTIONS
1) This chapter gives brief descriptions of the purpose and the role of
each function, the relationship between the electrical section and
the mechanical section, and the operating timing of each section.
The mark " " shows a mechanical transmission. If it is
togeth er with " " and a signal na me, it shows a flow of an
electric signal.
2) In the descriptions of the digital circuits in this chapter, "1" shows a
high voltage level of a signal, and "0" a low voltage level of a
signal. The voltage, however, differs in different circuits.
Though this machine employs a microprocessor, operational
descriptions on the microprocessor are omitted because it is virtually impossible to check inside the microprocessor.
Since the print PWB is not repaired by a user on principle, the
descriptions on the print PWB is limited to a brief one with block
diagrams. Therefore, the circuit descriptions of this chapter include
one from the sensor to the input section of the major PWB’s, one
from the output section of the major PWB’s to the load, and block
diagrams of each function.
1. Basic composition
A. Outline
This machine is composed of the following five sections: the reverse
section, the paper exit section, the intermediate process tray section,
the stapler section, and the stack tray section. The figure below
shows the composition.

Finisher controller
PWB
Fig. 3-101
B. Brief description of electric circuit
The operating sequence of the finisher is controlled by the finisher
controller PWB, which employs a 16 bit CPU to make sequence
control (and serial communication with the copier).
The finisher controller PWB drives the motor according to a command
sent from the copier through the serial communication line. It also
sends to the copier various information on the sensors and switches
through the serial communication line.
The major purposes of IC’s integrated in the finisher controller PWB
are as follows:
• IC1 (CPU)
Sequence control
• IC3 (EP-ROM)
Sequence program
• IC4 (Communication IC)
Communication with the copier (IPC II)
• IC12 (Regulator IC)

2. Basic operation
The basic operation is described below.
A. Face-up paper exit
In the face-up paper exit, the flapper solenoid turns on to switch the
paper path. Then paper passes through the following path.
B. Face-down paper exit
1) In the facedown paper exit, the flapper solenoid turns off to switch
the paper path, transporting paper to the reverse section.
3) Reverse rotation the semicircular roller furthermore to transport
paper to the paper exit roller side in the reverse section.
C. Face-up/face-down common operations
1) Paper is transported from the reverse section.
2) When the reverse entry port sensor detects the rear end of paper,
reverse rotation the semicircular roller to hold paper.
Fig. 3-201
2) Paper reaches the intermediate process tray.
Fig. 3-202
3) Paper is fed to make contact with the stopper plate by the return
roller.

Fig. 3-203
4) Paper is aligned with the front/rear alignment plates.
Fig. 3-204
5) Operations of 1) through 4) are repeated for the specified pages of
paper, and the pages are loaded on the intermediate process tray.
6) Stapling is performed. (Specified stapling position)

B. Paper exit
Paper fed from the copier is transported to the intermediate process
tray by the paper exit motor (M1). Paper transport is detected by the
entry port sensor (S2).
Paper feed guides A/B are provided at the paper exit port of this
machine. Paper feed guides A/B lower the rear edge of paper by their
weight to support transporting discharged paper to the return roller.

3. Transport system
A. Outline
Paper is fed from the copier and discharged to the intermediate
process tray, where alignment and offset and stapling are made.
Then paper is discharged to the stack tray.
A jam in the machine is detected by the entry port sensor (S2).

4. Intermediate process tray section
A. Intermediate process tray operation
(1) Outline
The intermediate process tray makes a bundle of paper to align,
offset, and staple paper discharged from the copier.
The intermediate process tray section is composed of the return roller
and the bundle process belt. The bundle process belt is provided with
the bundle exit lever. The two bundle process levers are driven in
parallel.
When paper is stored in the intermediate process tray, the intermediate process tray paper sensor (S5) turns on.
When the power is supplied to the copier, the bundle process motor
(M2) is driven to return the return roller and the bundle process belts
to their home positions.

(2) Bundle process motor (M2) control
The bundle process motor (M2) is a 4-phase stepping motor.
Forward/reverse rotation of the motor and the rotating speed are
controlled by the phase of the pulse signals BUNDPINA,
BUNDPINA*, BUNDPINB and BUNDPINB* sent from the CPU to IC6.
IC6 outputs pulse signals A, A*, B, and B* corresponding to the shift
of BUNDPINA and BUNDPINB to control the motor rotating direction
and the rotating speed.
The motor torque is controlled by the combination of current control
signals BUNDCURA and BUNDCURB sent from the CPU to IC6.
In this machine, the motor is driven at a high torque when driving the
bundle exit belt (forward rotation), and at a low torque when driving
the return roller (reverse rotation).

(3) Max. load capacity of the intermediate process tray
The max. load capacity of the intermediate process tray is shown in
the table below.
When the set number of pages or the number of documents exceeds
the max . load cap acity , the docu me nts of the max. lo ad capa cit y are
aligned and offset on the intermediate process tray. Then the bundle
of paper is discharged to the stack tray, and the remaining number of
paper is aligned.
When offsetting, all pages of a bundle are offset in the same direction.

B. Return roller
(1) Outline
The return roller leads the discharged paper from the copier to the
stopper plate to align in the transport direction.
The return roller is driven in the forward direction when the bundle
process motor is reversed.
Return roller
(2) Operational descriptions
The operational descriptions of the return roller are given below.
1) Paper is discharged from the copier.
Fig. 3-405-a
2) The return roller rotates forwardly, and the paper reaches the
intermediate process tray and makes contact with the stopper
plate.
Stopper plate
Fig. 3-405-b
3) The roller rotates one turn and stands by at the home position. In
the case of the large/middle size or manual paper feed, the return
roller holds paper at the stand-by position.
Fig. 3-405-c
4) When the next paper is discharged from the copier, operations of
1) and 2) are repeated to form a bundle of paper.
When the last paper of a bundle is brought into contact with the
stopper plate, the return roller passes the home position and stops
at 1/8 turn.

5) After completion of alignment of the first set, the bundle is discharged by the bundle discharge lever. At the same time, the
return roller rotates in the reverse direction. Since, however, the
return roller has been off from the home position, it does not
interfere the bundle.

6) The bundle process belt reaches the home position to complete
bundle exit. At the same time, the return roller stops at the home
position.

7) When the next bundle is fed, operations of 1) to 6) are repeated.
• Paper holding in manual paper feed of large/middle size paper
In the case of manual paper feed, the max. load capacity of the
intermediate process tray is 5 pages. For manual paper feed of
large/middle size paper, paper tends to be folded. To prevent
against this, the return roller holds paper until the next paper is fed.

(2) Operational descriptions
The operational descriptions of the bundle exit belt are given below.
1) Press the copy start key of the copier, and paper is stored in the
intermediate process tray. The return roller brings paper into contact with the stopper plate to align. The specified number of paper
is loaded in the intermediate process tray.

the stack tray.

C. Bundle exit belt drive
(1) Outline of operation
The two bundle exit belts are driven in parallel when the bundle
process motor (M2) rotates forwardly.
The bundle exit belt is provided with two bundle exit belts on the
opposing positions. A bundle is discharged with a half turn of the
bundle exit belts.
When the power is supplied to the copier, the bundle process motor
(M2) is driven to set the bundle exit lever to the home position.
Fig. 3-410-b
3) Just before the bundle is discharged to the stack tray, the bundle
exit belt speed is reduced to prevent against misalignment due to
collision.
