DESCRIPTIONS

1. Paper transport mechanism

The transport motor power is transmitted to the paper exit roller and
the paper feed roller.

2. Bin up-down shifi mechanism

The bin shift motor power is transmitted to the spiral cam @ (R side)

by the timing belt and the gear, and to the spiral cam ~
the same time by the drive shaft,
The bin is shifted up or down by foword or reverse rotation of the

motor. The bin is stopped at the stop position by the one rotation

sensor attached to the spiral cam Z.

When the power line reaches about 0.8V by turning on, IC5 starts operation and IC5 8 pin becomes

maintained until a certain time is passed after power line’s reaching about 4.3V. The reset maintaining time id determined by the capacity of Cl 7. It
is about 10Omsecfor this circuit. After passing the reset time, IC5 8 pin turns to HIGH to cancel reset, and the CPU resumes operation.

When the power line voltage falls to about 4,2V, IC5 8 pin turns to LOW to issue the reset signal, and the reset state is maintained as far as the
power voltage is lower than about 4.3V. After about 10Omsecfrom when the power voltage reaches about 4,3V, reset is cancelled.

IC5 3 pin is the watch dog timer clock sinal input pin, and the output signal from the CPU 6 pin is used as the clock. When the CPU normally
operates, the clock is regular pulse signal of 500/0duty and 5msec frequency, When the CPU is hung up or in an abnormal state, the clock is not
supplied, IC5 normally monitors this clock. When the clock supply is stopped, after a ceratin time, IC5 drives 8 pin to LOW to supply the reset signal.
The monitoring time of clock is determined by the capacity of Cl 7, and is about 10Omsecfor this circuit.
Hard reset is also applied from the PPC through the communication cable. In this case, CNI -5 pin

reset functions including the power on reset, the +5V abnormal fall reset, and the watch dog timer function.

This circuit is used to sense the presence of paper on the tray. CN4 ISconnected to the light emitting PWB, and CN5 is connectec

to the light

receiving PWB.

1. Light emitting circuit

The signal outputted from the CPU

(ICI 1-5 pin) at a certain frequency is inputted to ICI 2-11 pin, and the reversed output is inputted to the base of

Q2. Consequently Q2 turns onto light the LED.

The photoelectric current flowing through PT1 becomes the base current of Q1 and operates Q1 and is converted into the output voltage by R4. Part
of current flowing through Q1 is integrated by R2 and Cl and is passed to the base of Q2

to set the operating point of Q1 with Q2, PTI, and R3.

(The collector potential of Q2 is set to about 1,2V)

When disturbance lights (DC light, fluorescent light, etc. ) enters the light receiving element, the DC current in PT1 and Q1 tries to increase according
to the disturbance lights. However, this current is passed through R2 to the base of Q2, conducting Q2, Therefore, the photoelectric current
generated by disturbance lights becomes the collector current of Q2, and does not flow to the base of Q1 which has a higher impedance. In this
manner, an increase in the Q2 collector current is suppressed, and the operation is controlled, (When disturbance light increases, the Q2 emitter

voltage increases by R3, therefore the limit of voltage for normal operations is about 2.5V

or less. If there is no disturbance light, it is set to about

Ov.)

When fhe signal light becomes too intense, the same control is performed,

R2 and Cl forms the low pass filter which allows the fluorescent light completely to pass and does not allow modulated light to pass.

The signal outputted from the light receiving PWB is DC-cut by C6 and modulated by the comparator (IC9). (It is digitally converted by the
comparator, and the threshold value of the comparator is about 3,8V.)
The digital signal outputted from the comparator is latched by the flip-flop (IC3)

When D (2 pin) is HIGH at the rising edge of CLK (3 pin) of

the flip-flop (IC3), it is judged as “no paper” and the output Q (5 pin) becomes HIGH

When D (2 pin) is LOW (oV), it is judges as “paper present” and the output Q (5 pin) becomes LOW.

Upper/lower limit sensor (SEN8) circuit

1)

The bin home sensor (SEN2) circuit is used to sense that the tray is at the paper exit position of the first bin.
The sensor is of the photo transmission type (photo interrupter), and includes the LED and the photo transistor, The output level is normally LOW

(OV)because of light transmission,
When the tray reaches the paper exit position of the first bin,the LED light is interrupted and the output of the photo transistor becomes HIGH

(+5V).
Then the HIGH output is inputted to CN10-10 pm, and the converted LOW output (OV)is inputted to ICI 1-59 pin.

2)

The Entry port sensor (SEM1)circuit is used to sense that the paper discharged from the PPC enters the sorter entrance
After sensing, it operates in the same manner as the home sensor. The signal is inputted to IC11-60 pin,
The one rotation sensor (SEN3) circuit is used to sense that the tray is at a position suitable for paper exit or take-up.

3)

The sensor is of the photo transmission type (photo interrupter), and includes the LED and the photo transistor. The output level is normally LOW

(OV)because of light transmission,
When the lead cam reaches the stop position, the LED light is interrupted and the photo transistor output becomes HIGH (+5V).
Therefore the HIGH level output is inputted to CN1O-13pin, and its signal is inputted to IC11-72 pin.

4)

The take-out position sensor (SEN4) circuit is used to sense that the paper on the tray is at the take-up position in take-up mode.
The sensor is of the photo transmission type (photo interrupter), and includes the LED and the photo transistor, The output level is normally LOW

(OV)because of light interruption.
When the paper reaches the take-up position, the LED lights in interrupted, and the photo transistor output becomes HIGh (+5V).
Therefore the HIGH level output is inputted to CN1O-3pin, and the converted LOW signal is inputted to ICI 1-61 pin.

It isabout 1.2V by monitoring through connection between CN1O-1pin and IC11-63 pin, but becomes HIGH (+5V) when open.

Therefore the HIGH level output is inputted to CN9-2 pin and the converted LOW output (by IC12 is inputted to IC11-56 pin,

The bin shift motor clock sensor and the transport motor clock sensor are composed of the photo interrupter with built-in amplifier and the slit disc
attached to the motor shaft to obtain pulse signals according to motor rotation. The motor rotation speed is detected by the frequency of the pulse

This circuit is used to sense the sorter set state, and is connected with the microswitch. When the sorter is installed to the main body, the contact IS
closed. The microswitch is connected in series to +24V, and directly switches the power to each drive section. That is. each drive section is not
operated if the switch is open.

When the sorter set switch is on, +24V is applied to the cathode of ZD1, and a current flows through the base of Q1, turning on Q1 to input to IC1t

pin.

This circuit is used to drive the motor which takes paper discharged from the main body into the sorter. The drive signal (ONatLOW)outputtedfrom

the CPU is passed through the inverfor (IC12.6) and the HIGH output is inputted to the MOSFET (Q5) gate, turning on Q5. As a result. a current
flows through +241/L+ fhe motor + 05 + PGROUND to rotate the motor counterclockwise.

,,,4;.;,,,,,,

This circuit is used to control rotation, stop and rotating direction of the bin shift motor, and is composed of the logic IC and the power MOSFET (Q6

- Q9).

The rotation, stop and rotating direction of the motor are controlled by the combination of output Iogics of CPU 18 pin and 19 pin. The CPU 48 pin is

fhe PWM output pln for speed control.

First, In the normal rotation of the motor, !he CPU 18 pin is LOW, 19 pin IS HIGH, 48 pin is HIGH, ICI Op pin and 12 pin are HIGH, Then ICI O6 pln

becomes HIGH, IC2 8 pin becomes HIGH, conducting Q7 and Q8. On the other hand, since IC1O3 pin is LOW and IC2 12 pin is LOW, Q6 and Q8
is shut off. Therefore, a current flows through +24V1/L+ Q7 + CN8.1 - Motor + CN8.2 + Q8 - PGROUNDto rotate the motor clockwise (when
viewed from the output shaft).

Underthisstate,whentheCPU48 pin (PWM signal) is drive to LOW, ICI O6 pin becomes LOW to turn off Q7, interrupting power supply from +24V.

However, a regenerative current generated by the motor COIIInductance flows through PGROUND + Q8 flywheel diode + CN8.2 + motor A
CN8.1 + Q9 + PGROUND. In this case, the motor rotates in reduced speeds. The motor speed is controlled by controlling the pulse of the power

applied to the motor by adjusting the H/L duty of the PWM signal.

Nefi, in the reverse rotation, the CPU 18 pin is driven to LOW, 19 pin LOW, and IC1O9 pin and 12 pin HIGH, IC1O3 pin becomes HIGH and IC12

12 pin becomes LOW to turn on Q6 and Q9 and turn off Q7 and Q8. As a result, a current flows through +24V + Q6 + CN8.2 + motor+ CN8.1 +

PGROUNDin thereversedirectionof thenormalrotation,rotatingthemotorcounterclockwise.Thespeed control is performed in the same

Q9 +
manner as the normal rotation.

To stop the motor, the CPU 18 pin is driven to HIGH, ICl O3 pin and 6 pin become LOW, IC2 8 pin and 12 pin become HIGH, Q6 and Q7 are turned
off, Q8 and Q9 are turned on, and the both terminals of the motor are shorted to apply the brake. In the brake

generated to stop the motor.
When the bin reaches the limit position, the limit sensor signal and the bin home sensor signal are combined to control the stop signal of the motor.
At the upper limit, only the limit sensor senses tha signal, and the limit sensor signal becomes LOW and the home sensor signal becomes HIGH.

Therefore IC4 8 pin becomes LOW, IC4 11 pin becomes HIGH, and Q7 is turned off to stop the motor.

At the lower limit, both of the limit sensor and the bin home sensor sense signals, the limit sensor signal is LOW, and the home sensor si9nal is
LOW. Therefore IC4 11 pin is LOW and IC4 8 pin is HIGH, and Q6 is turned off to stop the motor.
