The transport system transports paper discharged from the copier to
the bin by the transport roller. The transport roller is driven by the
transport motor (M2).
The paper transport status is detected by the paper exit sensor (PS1)
on the sorter controller PWB.
The transport motor is a stepping motor of 4-phase control. The
transport speed is controlled with the number of pulses of pulse signals A, A*, B, and B* of the motor driver IC (Q23).

(2) Transport speed control
1) Outline
The transport speed is controlled by the transport motor (M2) and the
torque limiter. The transport motor changes the transport speed
depending on the paper size, and it keeps a fixed speed during
transporting without control of the transport speed.
The transport speed of this machine is higher than the process speed
of the copier. When copy paper is at the fusing section of the copier
and the transport roller of this machine at the same time, the transport
roller speed is reduced by the torque limiter.
2) Process speed
The process speed is the speed from when the copy paper is
received from the copier to when it is taken into the sorter completely.
It is the same as the process speed of the copier.
Transport roller
Sorter controller PWB
3) Taking in, paper exit speed
This is the transport speed after discharging of the copy from the
fusing section of the copier. It varies depending on the paper size.

Unfixed paper700mm/sec
(3) Stack over
1) Outline
The capacity of bins in each mode is limited as shown below. If the
capacity is exceeded, the stack over error occurs.
When the sorter detects a jam, it sends the jam signal (SJAM) to the
copier. Then the copier stops copying and displays "Paper feed
check" on the display section.
After completion of removing the jam, press the copy start key again,
and the jam-corrected number of copies are automatically made and
discharged to the bins.
When, on the other hand, a jam occurs in the copier, all the copy
papers under transportation in the sorter are discharged to the
specified bins and the operation is stopped.
Note: When a paper jam is detected in the sorter, separate the sorter
from the copier (the joint sensor is turned OFF), and remove
the jammed paper. Then reset the sorter to the copier, and the
trouble will be canceled.
1) Transport delay jam
The paper exit sensor does not detect the paper in 300msec of
transport time (which varies depending on the copier) after reception
of the paper exit signal from the copier.

the copier, all the copy papers transporting in the sorter are discharged to the specified bin and the sorter is stopped.
B. Bin unit drive system
(1) Outline
The bin unit drive system is composed of the following drive systems.
• Bin drive system
• Guide bar drive system
The bin is driven by the bin shift motor (M1), and moved up and
down.
The guide bar is driven by the guide bar motor (M3) to align the
discharged copy paper.
(2) Bin unit
1) Bin unit composition
The bin unit is composed as shown below.
The both sides of each bin are provided with the roller from the
outside of the bin frame. The dummy rollers on the upper and the
lower sides are integrated with the bin unit and fixed to the both ends
of the bin frame.

If, however, all the grooves in the lead cam were slanted, the lead
cam would be rotated by the weight of the bin unit when the bin unit is
stationary. To prevent against this, the groove has the horizontal
section as shown below. The lead cam home position sensor detects
the position so that the roller comes at the horizontal section when
the bin unit is stationary.
3) Bin shift motor control
The bin shift motor control circuit is shown below.
The bin shift motor (M1) is a DC motor, and controlled by the drive
circuit to move the bin unit up and down.
The up/down moving speed of the bin unit is detected and controlled
by the shift motor clock sensor.
The stop position of the bin unit is detected by the lead cam home
position sensor.
When the stapler unit is not in the home position, the +24V power is
interrupted by the stapler home position switch to stop the bin shift
motor in order to prevent against a crash of the bin unit and the
stapler unit.
An overrun is prevented by the bin unit upper limit sensor and the
lower limit sensor.
The current detection circuit is provided to detect an overcurrent when
the bin unit is interrupted by a foreign material. It stops the bin unit at
that time.

3) Guide bar oscillation motor (M3) control
The control circuit of the guide bar oscillation motor (M3) is shown
below.
The guide bar oscillation motor is a stepping motor of 4-phase control.
The sorter controller PWB sends drive pulses (GBMA, GBMA∗,
GBMB, GBMB∗) to the motor driver.
The motor driver controls the output timing of the pulse signals (A,
A∗, B, B∗) according to each signal to turn ON/OFF the guide bar
oscillation motor and switch the rotating direction.
When the guide bar oscillation motor (M3) is held, the output timing of
the pulse signals (A, A∗, B, B∗) is fixed.
The fuse (ICP2) breaks the power supply circuit when an overcurrent
flows through the circuit to stop the guide bar oscillation motor (M3).

(4) Bin paper sensor
1) Outline
The bin paper sensor is composed of the LED and the photo transistor. It detects paper in the bin.
This machine executes the paper detection level correction automatically and periodically to prevent against malfunctions due to light
quantity change in each sensor.
Note: When the sensor light receiving section (S2) is exposed to
external lights during correction of the paper detection level,
an erroneous correction value is stored. In such a case,
"E525" is displayed on the operation panel of the copier during
the normal operation.

(5) Other sensors
1) Bin unit lower limit sensor (Home position sensor)
The bin unit returns to the home position when the copy start key is
pressed ON or when all the paper in the bins are removed.
In that case, the actuator section integrated with the bin unit passes
over the bin unit lower limit sensor (PI4) to turn on the sensor, sending signals to the CPU of the sorter controller PWB.
When the bin unit is falling further from the home position, the lead
cam home position sensor turns OFF to detect the lower limit. The
sorter controller PWB immediately stops the bin shift motor (M1) drive
and displays the error code on the operation panel of the copier at the
same time.
2) Bin unit upper limit sensor
The bin unit upper limit detection is performed by the actuator section
integrated with the bin unit and the bin unit upper limit sensor (PI5).
When any abnormality occurs and the bin unit moves up further from
the 20th bin, the actuator section passes over the upper limit sensor
to turn on the sensor, sending signals to the CPU of the sorter controller PWB. It immediately stops the bin shift motor (M1) drive and
displays the error code on the operation panel of the copier at the
same time.

c. Stapler motor overcurrent protection
When the stapler motor starts rotation, the current detection circuit
detects the current flowing through the stapler motor.
When an overcurrent is detected, the current detection circuit
turns on Q54 and Q55 to control the stapler motor drive.
3) Stapler motor staple jam control
When a staple jam occurs in the stapler unit, the stapler motor (M5) is
controlled as follows.
1) An overload is applied to the stapler motor by a staple jam.
↓
2) The stapler does not return to the home position within about
0.6sec after starting stapling.
↓
3) The stapler mo tor is rotated in reverse to re turn to the home
position of stapling.
↓
4) An alarm is made to the copier.
4) Safety switch (MS3)
When your finger enters the stapling position, the actuator is lowered
to turn off the safety switch. When the safety switch is turned off, the
stapler motor (M5) power is cut off and the signal is sent to the CPU
to turn off the drive signal of the stapler motor (M5) to stop stapling.
5) Staple em pt y detection
The staple empty detection in the staple cartridge is made by the
staple empty detection switch (MS5) provided in the stapler.
The staples in the staple cartridge are pushed up by the spring and
the plate. the staples are also pushed toward the tip of the stapler.
When there are staples in the cartridge, the staple empty detection
switch (MS5) is pushed by the staples and the sorter controller
detects presence of the staples.
When the staples are exhausted (when the remaining quantity of the
staples becomes about 40 pcs.), the staple detection switch (MS5) is
opened (MS5: normal open), and the sorter controller detects staple
empty. At the same time, the sorter controller displays the staple
supply display.
When staple empty is detected, stapling is stopped. When, however,
staple empty is detected during continuous stapling, stapling is
stopped after completion of the job.

b. Operation
The microcomputer on the sorter controller PWB receives a command of the staple mode from the copier. The microcomputer (Q1)
sends the drive pulses (SPSWHA, SPSWHA∗, SPSWHB,
SPSWHB∗) to the driver circuit.
The motor driver circuit drives the stapler unit oscillation motor
(M4) according to the signal.
When the stapler unit oscillation motor is held, the output timing of
the pulse signals (A, A∗, B, B∗) is fixed.

(4) Paper holding
1) Outline
Paper holding is performed during stapling. The paper holding arm
presses paper by the stapler roller when the staple unit oscillates. At
the same time, the stapler unit bin supporting arm supports the bin
from the bottom to stable stapling operation.

3) Stapler unit oscillation motor control
a. Outline
The stapler unit oscillation motor (M4) control circuit is shown in
the figure below.
The stapler unit oscillation motor is a stepping motor of 4-phase
control. By controlling the outputs of pulse signals (A, A∗, B, B∗),
the stapler unit oscillation motor (M4) ON/OFF and its rotating
direction are switched.
The power supply circuit of the stapler oscillation motor (M4) is
provided with the stapler cover switch (MS2) and the fuse (ICP3).
The stapler cover switch cuts off the power supply circuit when the
stapler cover is opened. The fuse (ICP3) cuts off the power supply
circuit when an overcurrent flows through the circuit. The stapler
unit oscillation motor (M4) is stopped in that manner.

These signals are written into the RAM on the sorter controller PWB
and outputted according to the control signal from the CPU (Q1).
A serviceman cannot check if the status signal is properly transferred
or not. When, however, an error in signal transfer occurs, the self
diagnostics function of the copier functions to display the error code
on the operation section of the copier. (Code: F1-70)
