The feed rollers and the discharge rollers are driven by the transfer
motor via a high trail pulley, gear 24T, transfer belt, pulley 24T and
timing belt.

4. Separator section

• The solenoid-driven separator claw selects the paper passage be-

tween non-sorting and sorting paths.

• When the solenoid is OFF, the separator claw is in the lower

position so that the paper is discharged into the non- sorting bin.

• When the solenoid is ON, the separator claw is in the upper posi-

tion so that the paper is transferred by the suction belt and dis­charged into bins 2 through 20 by the indexer successively.

Discharge roller

<Sorting operation>

The separator pawl is in the lifted position so that the paper passes
under the pawl and is transferred by the suction belt to the indexer
which discharges the paper.

[6] ELECTRICAL CIRCUITS

1. General

The electric circuit controls the motions of taking in the sheets of
paper discharged from the copier and distributing them into bins 1
through 20. These motions are controlled by the control signals deliv­ered from the control circuit board based on the sensor outputs. The
circuit consists of the sensor input circuit which receives signals from

This circuit communicates with the copier. Input and output signals
handled are as follows.

a. DTR CN1-1P

Input from the copier, meaning that the copier has the right of
transmission when IC1-20P is at L level (0V).

b. DSR CN1-3P

Output from the sorter, meaning that the sorter has the right of
transmission during a period since IC1-20P changes from L level
(0V) to H level (+5V) until it returns to L level, when IC1-23P is at
H level (+5V).

c. TXD CN1-5P

Input signal from the copier. Data is received when ICI-18P
changes from H level (+5V) to L level.

d. RXD CN1-7P

Output signal from the sorter. Data is transmitted when ICI- 17P
changes from H level (+5V) to L level.

e. RES CN1-9P

Reset signal from the copier. CPU (IC1) is reset when CN1-9P is
H level (+5V).

a. Paper discharge sensor

This circuit monitors the presence of paper on the indexer and deter­mines whether paper is discharged onto the tray. CN6 is connected
to an infrared emitting LED and CN5 is connected to a light receptor
which receives the light from the LED.
Internal circuit of the light receptor is shown in the figure below.

The oscillator of the light receptor sends the output signal shown
below to the connector CN5-4P and SENVOL.
This signal is used to drive the LED to light in pulses, and the light is
sensed by the receptor where the synchronization monitor circuit in­corporated in it determines whether the light pulses are synchronized
with the VOL outputs.

When the power is turned on, IC6-8P in the figure turns from L level
(0V) to H level (+5V) in about 100ms, to complete the resetting opera­tion.
The reset circuit produces logical sum of the output from IC6-8P and
the reset signal from the copier. Reset is effected at the same time
the reset signal is received from the copier.
IC6 functions in such a manner, when the program stored in the
sorter starts to run upon completion of the resetting operation, if
IC6-3P receives clock signals at specified intervals (10ms) and the
CPU (IC1) and the program normally operate, the output of IC6-8P
goes to H level (+5V).
If a failure occurs such as panic run of the program to interrupt the
clock input, the system is reset within the monitor period of the watch
dog timer (about 100ms) determined by C1 (1µF), while the output of
IC6-8P remains at L level (0V). It, however, turns HIGH when a clock
input is applied within 100ms.

If no synchronization is observed, it means that paper is present
between the light emitter and the receptor.
Synchronization is determined to be lost when three pulses are not
synchronized.
When paper is present, output signal at H level (+5V) is fed to IC10­11P, and inverted L level (0V) is fed to IC1-13P.
Light intensity is adjusted with VR1 to optimize for the receptor.

b. Indexer lower limit sensor (ILLS) circuit,

Indexer position sensor (IPS) circuit

1 The indexer lower limit sensor (ILLS) circuit is to sense when the

indexer overruns bin 20 to reach the lower limit, due to overrun of
the indexer motor (IM) or a panic run.
ILLS is a sensor of transparent type which comprises a LED and a
photo-diode, where light is normally transmitted. Normal output
level is H (+5V), while the photodiode gives L level (0V) output
when the indexer reaches the lower limit to interrupt the LED light.

1 The indexer upper limit sensor (IULS) circuit is to sense when the

indexer overruns the indexer home sensor (IHS) to reach the
upper limit, due to overrun of the indexer motor (IM) or a panic

level is H (+5V), while the photodiode gives L level (0V) output
when the indexer reaches the upper limit to interrupt the LED light.
Consequently, L level output is fed to IC10-3P while inverted H

These circuits monitor the upper cover and the fan cover while they
open or close. Two switches are connected in series, and turn on
when the cover is closed and turn off the cover is open. Closing of the
upper cover causes the switch contact to close, pulling up the base
voltage of Q1 to H level and pulling down the collector voltage of Q1
to L level (0V), feeding it to IC1-40P.
Operation of the fan cover switch (FCSW) is similar to the above.

The DIP switch circuit is used to set the operation mode when operat­ing the sorter individually. Turning ON 1-4P of SW2 sets the signals
at IC1-19P, 34P, 35P and 36P to L level, respectively. The operation
modes are selected by the setting of the switch as shown below.

5 *2 *2 ON — Sorting no-paper test mode

*1 In the group paper presence test mode, the indexer shifts when

the SW1 (push switch) was pressed in selecting the paper pres­ence test mode.

*2 The sorting no-paper test mode is selected only by setting SW2-3

to ON regardless of the setting of SW2-1 and -2.

8. Explanation of the operation (circuit)

1 Non-sorting paper-feed test mode

Set the DIP switch as 1:OFF, 2:OFF, 3:OFF, close all doors and turn
on the power while pressing SW1. Pressing SW1 in about one sec­ond causes the fan motor to turn on and the test mode to start.
In this test mode, when the inlet sensor detects paper, the transfer
motor turns on to discharge the paper into the non- sorting bin (bin 1).
About seven seconds after the tail edge of the last sheet passed the
inlet sensor, the transfer motor stops.
Pressing Sw1 after the transfer motor has stopped causes the fan
motor to stop to exit from the test mode. If SW1 is pressed again, the
fan motor turns on and test mode restarts.

Pressing SW1 after the transfer motor has stopped causes the fan
motor to stop to exit from the test mode. If SW1 is pressed again, the
fan motor turns on and test mode restarts.

4 Sorting no-paper test mode

Set the DIP switch as 3:OFF (1 and 2 may be in any position), close
all doors and turn on the power while pressing SW1. After initializa­tion of the indexer, the transfer motor and the fan motor turn on and
the test mode starts. Pressing SW1 again ends the test mode.

5 Loaded operation mode (test with
commu nic a t ion with copie r )

The sorter is switched to loaded operation mode by a command from
the copier. Then a signal (22H 01H DATA1) which requests individual
loading operation sent from the master to the slave starts the individ­ual loading operation.

Remedy for jam

(1) When paper jams, LED2 blinks and all loads are turned off. Open

the door and take out the jamming paper, and close the door.
LED2 will turn off indicating the jam is removed. Then pressing
SW1 brings the machine into the state similar to that after ending
the test mode.

Canceling alarm

(1) In case of alarm, LED2 blinks and all loads are turned off. The

alarm can be canceled by power ON reset.

vacuum fan (PVF) circuit

Gate solenoid (GS) circuit

2 Grouping paper-feed test mode

Set the DIP switch as 1:OFF, 2:OFF, 3:OFF, close all doors and turn
on the power while pressing SW1. Pressing SW1 in about one sec­ond causes the fan motor to turn on and the test mode to start.
In this test mode, when the inlet sensor detects paper, the transfer
motor turns on to discharge the paper into the non- sorting bin (bin 1).
If SW1 is pressed when the transfer motor is ON after the transfer of
paper, the indexer is lowered by one level when the next sheet of
paper turns on the inlet sensor. Pressing SW1 twice (* ) causes the

turning on, and the inlet gate opens to discharge paper into bin 2 and
the subsequent bins.

Circuit diagram

indexer to lower by two levels. Once the indexer reaches bin 20,
subsequent sheets are all transferred into bin 20 even if SW1 is
pressed.
About seven seconds after the tail edge of the last sheet passed the
discharge sensor of the sorter, the transfer motor stops.
Pressing SW1 after the transfer motor has stopped causes the fan
motor to stop to exit from the test mode. If SW1 is pressed again, the
fan motor turns on and test mode restarts.

3 Sorting paper-feed test mode

Set the DIP switch as 1:ON, 2:OFF, 3:OFF, close all doors and turn
on the power while pressing SW1. Pressing SW1 in about one sec­ond causes the fan motor to turn on and the test mode to start.
In this test mode, when the inlet sensor detects paper, the transfer
motor turns on to transfer the paper. Then every time the next paper
activates the inlet sensor, the indexer moves to the next bin. Upon
completion of paper transfer into bin 1 or 20, the indexer reverses its
moving direction.
About seven seconds after the tail edge of the last sheet passed the

a. CW rotation (down motion)

When IC1-3P output is H level (+5V) and IC1-4P is L level (0V),
IC3-2P and 6P are L level (0V) and 4P and 8P are H level (4P: +24V,
8P: +24V). Consequently, IC5-2P and 6P become L level (0V) and 4P
and 8P become H level (4P: +5V, 8P: +5V), causing the indexer
motor (IM) to rotate CW.
The motor can be turned ON/OFF with IC3-9P; stop at L level (0V),
rotatable at H level (+5V).
In case the lower limit sensor (ILLS) is activated due to software
panic or other reason, hardware protection is provided which stops
the motor using ILLS signal to prevent the motor from locking while
being kept ON.
When the motor is running CW, current flows as shown below.

b. CCW rotation (moving up)

When IC1-3P output is L level (0V) and IC1-4P is H level (+5V),
IC3-2P and 6P are H level (2P: +5V, 6P: +24V) and 4P and 8P are L
level (0V). Consequently, IC5-2P and 6P become H level (2P: +5V,
6P: +24V), and 4P and 8P become L level (0V), causing the indexer
motor (IM) to rotate CCW.
The motor can be turned ON/OFF with IC3-9P similarly to the case of
CW rotation; stop at L level (0V), rotatable at H level (+5V).
In case the upper limit sensor (IULS) is activated due to software
panic or other reason, hardware protection is provided which stops
the motor using IULS signal to prevent the motor from locking while
being kept ON.

level (0V). When the motor has stabilized at low speed running, PFM
delivers L level (0V) READY signal. This signal is fed to IC9-1P where
it is inverted to H level (+5V) and is fed to IC1-16P.
When the motor is locked, a protection circuit provided in the PFM
shuts off current flowing in the motor within 5 sec. This protective
action is reset by restoring IC1-5P from H level to L level.
