1. Transport route

The 3-tray finisher’s transport routes are as follows.
a) Tray 1 face-down paper discharge

c) Tray 3 outside turn face-down paper discharge

b) Tray 2 face-down paper discharge

2. Explanation of each section

The 3-tray finisher consists of (1) an upper paper transport section,
(2) a reversion section, (3) a staple tray, (4) an offset tray, and (5) an
elevator section.

It has the following functions: Paper discharge to a selected tray,
paper reversion, stapling for paper delivered to the offset tray (3
positions), offset, and elevation. Each function is performed according
to the mode instructed by the copier.

8/19/1999 4 – 1

5)

AR-FN3

A. Upper paper transport section

1) Paper transport

By rotating the main driving motor (FM), the transport rollers in the
finisher are driven.

2) Paper discharge gate 1 (1)

The paper discharge gate 1 (1) is operated by the paper discharge
gate 1 solenoid (OG1SL), to select between the routes for paper
discharge to the tray 1 (8) and transport to the tray 2 (5)/staple tray.

3) Paper discharge gate 2 (6)

The paper discharge gate 2 (6) is operated by the paper discharge
gate 2 solenoid (OG2SL) to select between the routes for paper
discharge to the tray 2 (5) and transport to the staple tray.

4) Trays 1 (8) and 2 (5) paper discharge operation

When paper is discharged to tray 1 (8) and tray 2 (5), tray 12 reduc­tion clutch (11) is operated at the paper discharging timing to reduce
the speed of paper discharge rollers 1 and 2, improving the accuracy
of paper alignment in tray 1 (8) and tray 2 (5).

5) Trays 1 (10) and 2 (7) paper full detection

Whether the trays 1 (10) and 2 (7) are filled with paper is detected by
the tray 1 and 2 paper full sensor.

B. Staple tray

1) Jogger motor (JGM)

The jogger motor is driven when the paper is fed into the staple tray,
to operate the jog plates F and R so as to align the sideways edge of
the paper.

2) Paddler (11)

The paddler clutch (PDCL) is turned ON when the paper is fed into
the staple tray, to give the paddler a full turn so as to drop the paper
downward (pusher), thus achieving alignment in the vertical direction.

3) Pusher motor (PSM)

With the pusher motor rotating, the paper stored inside the staple tray
is lowered from the home position (discharge position) to the stapling
position; after stapling, the paper inside the staple tray is elevated
from the stapling position to the home position.

4) Staple unit movement motor (STUM)

The staple unit is moved to the stapling positions (front, far end, 2
centers) by the staple unit motor.

5) Staple tray paper discharge

When the paper delivery roller pressure release clutch (STORCL) is
turned ON, the paper delivery pressure release roller (4) is pres­surized through the cam to discharge the paper from the stable tray.

6) Paper discharge gate 3 (5)

The paper discharge gate 3 (5) is operated by the paper discharge
gate 3 solenoid (OG3SL) to switch over the routes of paper inside the
staple tray between the paper discharge side and the staple side of
the off-set tray.

7) Tray 3 paper discharge motor

The tray paper discharge motor (12) is rotated to drive the paper
discharge rollers 3 and 4 to discharge paper to the tray 3.

Jogging in lateral direction

1) The jog plates are moved to the stand-by position before the
paper is fed to the staple tray.

2) Immediately after the paper is fed into the staple tray, the jog plate
is moved to the paper size position to ensure the alignment of the
paper.

Stapler unit movement at the time of stapling
(2-point stapling action is added.)

1) The pusher is elevated to the position which makes it possible for
the staple unit to move.

2) The staple unit is moved to the staple position where the 2nd
staple is driven.

3) The pusher (sheets to be stapled) is lowered to the stapling posi­tion.

4) Sheets are stapled.

5) The staple unit is returned to the 1st staple position.
(After the job is finished, the staple unit is returned to the home
position.)

D. Off-set tray

1) Off-set motor (3)

When the off-set motor (3) is driven, the tray is shifted sideways
against the direction in which the sheets are delivered, so that the
sheets discharged into the off-set tray (1) are sorted by the specified
number of sheets. The rotation is unidirectional and controlled by the
crank. The motor is stopped by the off-set home position sensor (2)
turning ON.

E. Elevator

1) Elevator motor (3)

When the elevator motor (3) is driven, the winding pulley (5) is rotated
in both forward and reverse to wind up the wire (6) stretching vertical­ly so that the tray 3 (off-set tray) is moved up and down. This allows
the discharge of paper at a fixed position according to the number of
sheets to be loaded on the off-set tray.

2) Off-set tray full and load detection

When the power is turned ON, the off-set tray lowers to the lower limit
sensor (4) position. Then it elevates until the upper limit sensor (7)
turns ON, while counting the encoder pulses of the elevator motor (3).

The volume of paper loaded on the off-set tray is calculated (0 ­100%) by counting the number of pulses from the elevator encoder
(1).

The off-set tray is judged to be full when both the lower and upper
limit sensors (4), (7) are turned ON.

5. Communication buffer and reset circuit

In the communication buffer circuit, the transmission signal (F-TXD)
and communication permit signal (F-DTR) from the copier are
received by the buffer IC 74HC14 (IC101), while the reception signal
(F-RXD) and communication request signal (F-DSR) transmitted from
the finisher to the copier are outputted from the transistor Q101 and
Q102.

The reset signal from the copier is also received by the IC101 and
inputted to the CPU’s reset terminal (active at L). In addition, the
reversion signal is inputted to the expansion I/O reset terminal (active
at H). For each signal, a protective diode is inserted between +5V and
GND.

7. Switch input circuit

This circuit checks whether the finisher is connected to the copier,
both the top and front doors are opened. It is connected to micros­witches whose contacts are closed when the finisher is connected to
the copier or the doors are closed.

Each switch is connected in series from +24V so that it becomes a
power supply switch for the drive. That is, +24V is conducted only
when all the 3 microswitches are closed.

When the finisher is connected to the copier, the microswitch turns
on, letting +24V be applied to ZD4. This allows electric current to flow
to the base resistance of the transistor array TD62504 (IC102), thus
turning on the transistor to change the expansion I/O PG1 (DSW1
signal) to L level.

When the finisher is disconnected from the copier, the transistor is
turned off to change the expansion I/O PG1 to H level. ZD4 (RD6.2E)
has a threshold level preset, to increase detection speed when the
supply of +24V is cut off. The levels of PG2 and 3 (DSW2, 3 signals)
also change when the top and front door switch is opened and
closed.

In addition, when +24V power supply from the copier is cut off, the
expansion I/O PG0 (PWD signal) level changes at the above circuit.

The expansion I/O PG port which controls the solenoids and clutches
is an open collector type which becomes high impedance when reset­ting and H output. For this reason, to turn on the solenoids and
clutches at L level, the non-inversion type TD62318AP is used for
driving the PG port. On the other hand, the expansion I/O’s PC port is
at L level at resetting. For this reason, for driving the PC port, the
inversion type M63823P which turns on the solenoids and clutches at
H level is used.

11. Elevator motor drive circ uit

24V3

The elevator motor control signal (EMA, B) from the expansion I/O is
inputted through the driver TD62503F (IC103) to the H driver
STA457C (IC5), to drive the elevator motor which adjusts the tray
height according to the paper volume stored in the off-set tray (tray

3). EMA,B signal logic controls the rotational direction of the motor
(CW/CCW) to move up and down the tray.

The motor is braked to improve the stopping accuracy of the tray.

TD62503 (IC103) is a driver for driving STA457C, consists of
peripheral resistors, capacitors, and diodes, which forms a delay cir­cuit to prevent short electric current from flowing inside the H driver
when EMA and B are changed over.

To protect the circuit from shorting and motor locking, a protective
fuse (F3) is installed.

13. 10V power generating circuit

The 10V power generating circuit generates +10V which is supplied to
the power supply of the transport motor IC uPD1246C (IC13) and
comparator BA10393F (IC104). The circuit consists of a Zener diode
RD11EB (ZD7), transistor 2SC1472 (Q5), other peripheral resistan­ces and capacitors. +24V is reduced to about +11V by the Zener
diode ZD7 and passed through the emitter follower circuit of the
transistor Q5 to become about +10V for outputting.

14. Transport motor drive circuit

The transport motor drive circuit consists of a motor IC yP1246C
(IC10), transistor array TD62503F (IC16), motor driver IC SLA6023
(IC20) and peripheral circuits.

When the transport motor control signal (FMPWM) from the CPU
becomes L level, the transistor inside the IC20 turns on to let the
motor current flow to start the motor. When the motor is started, the
transport motor hole signal (HU, HV, HW) input to the IC10 is
changed over to switch over the drive of the transistor inside the IC20
so that the motor begins to rotate under non-controlled state.

As the transport motor rotates, the speed signal (FMRE) is output
from the motor. The CPU incorporates the signal. It reduces the ON
duty of the FMPWM signal to increase the speed when the motor
speed is slow; it increases the ON duty of the FMPWM signal to
reduce the speed when the motor speed is high. The motor speed is
thus maintained at a constant speed.
As the current flowing into the motor becomes large, the current
flowing to the R25 also becomes large, thus raising the voltage at the
negative side of the comparator BA10393F (IC15). When this voltage
becomes greater than the reference voltage (about 1.1V) preset at
the plus side, the output of IC15 becomes at L level, thus turning off
the IC20 transistor to restrict the current flowing to the motor (current
limit setting: about 5A).

TD62503 (IC105) is a driver to drive Q1 ∼ 4. A delay circuit is com­posed of peripheral resistors, capacitors, and diodes to prevent short
current from flowing into the H driver circuit which is formed by Q1 ∼
4, when STMA and STMB are changed over.

The staple motor has a large rush current. It thus has a current limit
circuit consisting of a voltage comparator BA10393F (IC104) and
peripheral resistances and capacitors, to apply current limit at about

5.3A. To prevent the circuit from shorting or motor locking, a protec­tive fuse (F2) is installed.
