Section IV Electrical
4.1 Electrical parts Operation
(1) Bin motor control
(a) The bin motor moves the bin unit up and down, and is a +24V DC motor.
The motor control circuit is designed as shown below.
(b) The drive for this motor is controlled by a combination of drive signals(P34,P35)
from IC1 on the CPU P.C.B..
(c) The bin ass'y is moved up when signal [Low] is output from P34 of IC1 on the
CPU P.C.B. and signal [High] is output from P35. The [Low] signal from P34
turns Q9 ON and Q8 OFF, causing current flow to the bin motor.
In addition, the [High] signal from P35 turns Q6 ON and Q7 OFF, supplies
+24V to the bin motor and turns the motor.
(d) The bin ass'y is moved down when signal [High] is output from P34 of IC1 on
the CPU P.C.B. and signal [Low] is output from P35. The [High] signal from
P34 turns Q8 ON and Q9 OFF, supplying +24V to the bin motor.
In addition, the [Low] signal from P35 turns Q6 OFF and Q7 ON, causing the
rotation of the bin motor.
(e) The bin motor is stopped when the signals at P34 and 35 are changed [High].

(2) Paper transport motor control
(a) The paper transport motor is a +24V DC motor that drives the paper feed
roller of the staple sorter. The paper speed is regulated by controlling this
motor speed (Low,Mid and High). Its control circuit is designed as shown below.
(b) P21,23-25 of the sorter CPU P.C.B. IC1 generates a combination of signals
according to the desired condition, and controls the speed of the transport
motor.
(c) When one of the signals from P21,23,24 is [Low] and P25 and the remaining
pins signals are [High], the transistor corresponding to the [Low] signal is turned
ON ,supplying power to the zener diode, and this voltage is applied on Q11
base. When this voltage is lower than
V
BE of Q11, Q11 turns ON,causing the
rotation of the motor.
(d) The paper transport motor is stopped when the signal of P25 is [Low] and the
signals of P21,23,24 are [High]

(3) Tamper drive motor control
(a) The tampers are driven by a 2 phase energized type pulse motor. The design
of the control circuit of the staple guide bar drive motor is as shown below.
(b) When the pulse signal from P16 of the sorter CPU P.C.B IC-1 is output, this
signal energizes and drives the pulse motor.
(c) The rotating direction of the motor is controlled by the signal from P15 of IC-1.
(d) When the signal from IC-1 (P17) becomes [High], Q15 is turned ON, supplying
the current to lock the motor in its position.
(4) Staple swing motor control
(a) The stapler unit is driven to the staple position by the staple swing motor. This
staple swing motor is a +24V DC motor and its control circuit is as shown
below.
(b) [High] signal output from P32 of CPU P.C.B IC-1 and [Low] signal from P33
drives the motor by supplying +24V on one side of the motor and grounding
the other side of the motor.
(c) The motor is stopped when the signals of P32 and 33 of CPU P.C.B IC-1
become [High].

(5) Staple motor control
(a) The staple motor that drives the stapler is a +24V DC motor. Its control circuit
is designed as shown below.
(b) The staple motor is controlled by a combination of drive signals from the sorter
CPU P.C.B. IC1(P37,P36).
(c) Staple drive is performed by outputting [High] signal from P36 and p37 of the
sorter CPU P.C.B. IC1. The [High] signal from P36 turns the transistor Q13
ON and Q14 OFF, and +24V is supplied to 2C of RI1.
In addition, the high signal from P37 turns RY1 OFF, and the contact
point C of RY1 is connected to the contact point NC, and one side of the motor
is supplied with +24V while other side of the motor is grounded, thereby rotating
the motor.
(d) In case a failure occurs during staple operation, the signal from P37 changes
to [Low] and RY1 is turned ON. With this, the contact point is switched and the
staple motor rotates in reverse.
(e) When the staple motor stops,the signal from P36 changes to [Low].
