1.2 Features
• Auto two-sided original feeding system
• When two-sided originals are loaded, the originals are automatically turned over
to copy both sides according to the copy mode selected at the copier.
• Function to count originals
• In auto two-sided copy mode, if the counted number of originals is an odd number,
the first copy will be a one-sided copy then the subsequent copies will be twosided.
• Original size feeding system
• Originals of different size but with the same width (Ledger/Letter, A3/A4) can
be combined for feeding.
• Realization of space saving
• Power unit is installed in the copier, so the former bump is removed.
• Capable of feeding originals up to Ledger/A3 size.

4. 1 Function of electrical parts
(1) Original detecting sensor / Registration roller sensor
( Original detecting sensor )
•Detects originals in the original feed tray.
1) When an original is loaded in the original feed tray, it will contact the original
stopper. The original detecting sensor lever, which is positioned in front of the
original stopper, is raised and detects the presence of an original.
2) As soon as the original is detected, the ADF indicator in the copier's display
lights up and ADF operation is enabled.
Original
feed roller
Regist roller
( Registration roller sensor )
•Detects the original feed status and counts the number of originals.
1) When the paper feed roller is rotated, an original is fed to the registration roller,
then registration roller rotates to feed the original. The registration roller sensor
counts the number of originals which pass and informs the copier.

•Detects the tail edge of original
1) During registration roller operation, an original is fed to the transport belt. At the
same time, the timing sensor detects the tail edge of the original to control
original feed operation.
(2)Weight / Stopper solenoid
1) When the weight/stopper solenoid turns ON( 1 ), weight shaft rotates in the
direction indicated by arrow( 2 ) and the weight plate contacts ( 3 ) the original.
The pressure is determined by the weight of the weight plate and tension of the
spring.

(3) Original feed drive
•In order to feed an original, the motor rotates the paper feed and pick-up rollers.
1) When the original feed motor rotates ( forward rotation / A direction ), pully 56
is driven by timing belt 82, and one way pully 18 (which is mounted on the
same shaft) also rotates.
2) At the same time, pully 50 is driven by timing belt 72, and gear 21 (which is
mounted on the same shaft) also rotates.
3) Then gear 30, 32, 32OW also rotate as well as the pick-up roller and paper feed
roller .
•In order to feed the original from the original feed area to the transport belt, the
registration roller also rotates.
1) When the original feed roller is driven ( reverse rotation / B direction ), pully 56
is driven by pully 20 and timing belt 82, and one way gear 30OW (which is
mounted on the same shaft) also rotates.
2) At the same time, gear 21 is also driven so the registration roller turns.

4.3 Explanation of circuit
1.ADF CPU P.C.B.
(1) Comunication circuit
This circuit allows both serial and parallel communication between the copier
and the ADF. IC10 is used for serial communication. Data is transferred as
both a normal and inverse signal, so that any line noise will be cancelled out by
adding the two signals together inside IC10. The ADF also communicates with
the copier using 2 parallel data lines. One line for output using IC4 and Q3
(buffer) and the other for data input using pull up resistor.

5) Registration sensor ( REGS ) / Timing sensor ( TIMS )
The registration sensor and timing sensor is a reflection type of photointerruptor
which consists of an LED and phototransistor. The phototransistor detects the
reflection of infrared light from the LED for detecting the original.
The cathode terminal of the LED is connected to a voltage-current converting
circuit and D-A output ( Analog voltage output ) from the CPU controls the input
current for the LED. In addition, the photocurrent of the phototransistor is
converted to a voltage value by resistors. They are connected to the input
terminal of the sensor, to the input comparator circuit via a noise filter for
comparing to the reference voltage ( Aprrox. +2V ). When the output voltage
from the sensor is higher than reference voltage, the output signal from the
comparator circuit becomes Low, and transfers to the CPU as no original
detection.
The CPU controls the input current for the LED ( brightness of LED ) to maintain
proper sensor output voltage.

6) Original exit / reverse sensor ( HANS )
The original exit/reverse sensor is a reflection type of photointerruptor which
consists of an LED and phototransistor. The phototransistor detects the reflection
of infrared light from the LED for detecting the original.
The sensor input voltage is divided 1/3 by R87 and R88 and inputs to the A-D
converter. Then PWM signal which is a corresponding output from the A-D
converter, is output from the gatearray ( IC14 ). This PWM signal is converted
to analog voltage by an integrating circuit ( R2, C12 ) and is amplified 2 times
by a non-inverting amplifier to be a reference voltage for the comparator.
The reference voltage for the comparater is 2/3 of the high level of each sensor
output.
Also,during a no original detecting condition, the input voltage to the CPU is
less than 1V, pin 49 of CPU becomes high to increase brightness of the LED.
This circuit is the input circuit for the ADF open/close detecting switch, original
feed cover open/close detecting switch, and exit cover open/close detecting
switch. When one of these switches are in the OFF condition, the power ( DC
24V ) to all motors and solenoids is cut. The 24V ON/OFF signal is input to a
zener diode which reduces the voltage to DC 17.2V, and this lower voltage is
input to the base terminal of the transistor to convert a DC5V signal. The DC
5V signal is, then input to the CPU.

(3)Reset circuit
This circuit resets the CPU and output reset signal for the gate array.
When the DC 5V line drops to less than 4.3V (or immediately after the power is
turns ON) the output of IC6 is set to a low level. ( After power is turned ON and
the DC 5V line is higher than 4.3V, the reset is maintained for a while.) Also,
this circuit is a timer which is monitoring the CPU status to avoid abnormal
operation.

(4) Drive circuit
1) Original feed motor( DFM ) drive circuit
This circuit controls the forward and reverse movement of the original motor
which is a gatearray ( IC14 ), hybrid IC ( IC15 )and other components.
The CPU outputs the control signal ( 2 bits control signal ) to the gatearray
through a data bus for operating the original feed motor. The gatearray outputs
the original feed motor control signal from pin 65~68. Pin 65 and 66 of the
gatearray output the PWM signal for controlling the original feed motor speed.
( Forward rotation : pin 65 / Reverse rotation : pin 66 )
IC15 is a hybrid IC which is 4 elements of power MOSFET, and input control
signals from pin 65~68 from the gatearray is output for driving the original feed
motor. The original feed motor is driven the combination of control signals
which are output from pin 65~68 of gatearray ( IC14 ).
2) Transport belt motor ( DTM )/ Original reverse motor( DRM ) drive circuit
This circuit controls the forward and reverse movement of the transport belt
This circuit controls the original feed solenoid and the original reverse solenoid.
Operation of both the original feed solenoid and the original reverse solenoid
drive circuit is the same. When the drive signal from the gatearray becomes
HIGH, FET ( Q10,Q11 ) turns ON and the solenoid is activated.

(6)Rush current control circuit
This circuit controls the rush current for the capacitors ( C48, C49 ) in the
transport belt motor and original belt motor drive circuits and is a limiting resistor
and FET.
This circuit limits the current by R93 until so the voltage of the cathode terminal
of ZD7 reaches the reference level ( 16V ). When all of the ADF open/close
detecting switch, original feed cover open/close switch, and original exit cover
switch are closed, or power is turned ON to the ADF. After the voltage of
cathode terminal of ZD7 reaches reference level, this control is cancelled. R30
is a discharge resistor for C48 and C49, when either ADF open/close detecting
switch, original feed cover open/close switch, or original exit cover switch is
opened.
