General Precautions for Installation/Servicing/Maintenance
for the MR-3016
The installation and service should be done by a qualified service technician.
1) When installing the MR-3016 to the Equipment, be sure to follow the instructions described in the
“Unpacking/Set-Up Procedure for the MR-3016” booklet which comes with each unit of the MR3016.
2) The MR-3016 should be installed by an authorized/qualified person.
3) Before starting installation, servicing or maintenance work, be sure to turn OFF and unplug the
equipment first.
4) When servicing or maintaining the MR-3016, be careful about the rotating or operation sections
such as gears, pulleys, sprockets, cams, belts, etc.
5) When parts are disassembled, reassembly is basically the reverse of disassembly unless otherwise
noted in this manual or other related materials. Be careful not to reassemble small parts such as
screws, washers, pins, E-rings, toothed washers to the wrong places.
6) Basically, the machine should not be operated with any parts removed or disassembled.
7) Delicate parts for preventing safety hazard problems (such as switches, sensors, etc. if any) should
be handled/installed/adjusted correctly.
8) Use suitable measuring instruments and tools.
9) During servicing or maintenance work, be sure to check the serial No. plate and other cautionary
labels (if any) to see if they are clean and firmly fixed. If not, take appropriate actions.
10)The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband,
because the ICs on it may be damaged due to static electricity. Before using the wrist band, pull out
the power cord plug of the equipment and make sure that there is no uninsulated charged objects in
the vicinity.
11)For the recovery and disposal of used MR-3016, consumable parts and packing materials, follow the
relevant local regulations/rules should be followed.
12)After completing installation, servicing and maintenance of the MR-3016, return the MR-3016 to its
original state, and check operation.
PREPARATION FOR TRANSPORTATION OF EQUIPMENT
Before transporting the equipment on which mounts the MR-3016, take off the MR-3016 or insert some
cushioning material underneath the MR-3016 as shown in the following figures.
1) Use pieces of the corrugated board came in the package of MR-3016 or equivalent as the cushioning. Insert the cushioning as shown in the figure, then close the MR-3016.
Height positioning stud
Cushioning
2) Make sure that the height positioning stud is not in contact with the original glass.
Cushioning
The height positioning stud is not in
contact with the original glass.

Description of Interface Signals
The following 6 lines are used to transmit/receive signals between the equipment and the RADF.
REQ ......................Communication request signal (from equipment to the RADF)
DF-REQ ................Communication request signal (from the RADF to equipment)
DF-ACK.................Communication request acknowledging signal (from the RADF to equipment)
ACK.......................Communication request acknowledging signal (from equipment to the RADF)
TxD .......................Data transmitted from equipment to the RADF
RxD .......................Data transmitted from the RADF to equipment
Data communication (RxD and TxD) between the scanner and the RADF has adopted the serial communication system which does not allow checking using testing devices to see whether the signals are
transmitted/received properly in the field.

Adjustment error of sensors
(Original length sensor adjustment error, read sensor adjustment error and reverse sensor adjustment
error)
*
Error detection
When A/D input voltage of each sensor is from 3.16 V to 3.55 V (no paper), the corresponding D/A
output voltage is adjusted to be from 0.04 V to 2.90 V. If this input/output condition is not satisfied, an
error occurs on each sensor.
6.5.3
*
Error detection
An error occurs;
• When the default value is failed to be written on the EEPROM at initialization and all-sensor
adjustment with the test codes.
• When the data is not read from the EEPROM at power-ON
6.5.4
*
EEPROM error
Fan motor lock error
Error detection
The lock detection timer (2 sec.) is set when the fan motor starts rotating, and the lock detection signals input from the fan motor is checked at the intervals of 5 msec. If the fan motor is not locked, the
setting of the lock detection timer is cleared. The lock is detected as an error if the locked status is
detected for more than 2 seconds even though the fan motor is being driven.

ORIGINAL SIZE DETECTION
The original size is detected on every feeding of original, and data of the original size along the feeding
direction and width size are transmitted to the equipment before the scanning starts.

MR-3016 ORIGINAL SIZE DETECTION
7-1
7.1
Method of Original Size Detection (for Normal Operation)
1) Original position reference code
When the paper feeding signal is received, the guide width of the tray is checked and memorized.
Even if the guide position is changed during operation, the changed guide width is invalid.
2) Width
When the original waiting at the pre-feeding position has started to be fed and its leading edge has
passed the registration roller over 67.2 mm, the size data and the states of the original width sensors
-1 and -3 are saved.
3) Size along feeding direction
When the leading edge of original has reached the read sensor and further reached to the deceleration starting position for the scanning waiting position, the original size is judged by the states of the
original width sensors -1 and -3 saved previously and ON/OFF state of the original length sensor.
Then the original size data are transmitted to the equipment (the size along feeding direction first,
then the width).
Original size: LT or smaller

7.2
Method of Original Size Detection (for Mixed Sized Originals)
1) Original position reference code
When the paper feeding signal is received, the guide width of the tray is checked and memorized.
Even if the guide position is changed during operation, the changed guide width is invalid.
2) Width
When the original waiting at the pre-feeding position has started to be fed and its leading edge has
passed the registration roller over 67.2 mm, the size data and the states of the original width sensors
-1 and -3 are saved.
3) Size along feeding direction
When the leading edge of original has reached the read sensor and further reached to the deceleration starting position for the scanning waiting position, the original size is judged by the states of the
original width sensors -1 and -3 saved previously and ON/OFF state of the original length sensor.
Then the original size data are transmitted (the size along feeding direction first, then the width).
If the original length sensor is ON, however, there are some combinations that the original size cannot be judged. In this case, the original is transported without scanning in reverse to count the feeding motor pulses until its trailing edge has passed the original length sensor. Then the original size is
judged by evaluating all these factors and the size data are transmitted to the equipment (the size
along feeding direction first, then the width).
Original size: LT or smaller

10.1 Input Circuits for Original Length Sensor, Read Sensor and
Reverse Sensor
Since original length sensor, read sensor and reverse sensor have almost the same circuit configurations (the reference voltage of comparator for read sensor input circuit can be set by D/A output), the
input circuits for the read sensor and reverse sensor are not described. The following is the input circuit
for the original length sensor.

This circuit is an input circuit for the original length sensor and consists of a voltage-current conversion
circuit which adjusts the amount of light of the infrared LED and the voltage comparison circuit which
compares the voltage output from a phototransistor (PTR) with a reference voltage and converts the
output voltage into digital signals.
The original length sensor is a mirror reflection sensor, and consists of a pair of emission elements
(infrared LEDs) and a light receiving element (PTR). Both elements have a light axis running in the
same direction. There is a mirror on the extended light axis of these elements. When there is no original
between the elements and the mirror, infrared light emitted from LED is reflected by PTR in high reflectance. If there is an original, light emission to the mirror and reflected light from the mirror are blocked
by the original, and the reflected light entering PTR becomes extremely small.
When a large amount of light is entering PTR (this means there is no original) the optical current flowing
in the PTR is increased, and the voltage of Pin10 - IC3 becomes higher due to a drop in voltage caused
by R44. IC3 is a comparator which compares the reference voltage input to Pin11 (non-reverse input
terminal) with the signal voltage of Pin10 (reverse input terminal). If the voltage of Pin10 is higher, the
output level (Pin13 - IC3) is “L”. On the contrary, when the amount of the incoming light is small (this
means there is an original), the voltage of Pin10 - IC3 is low and the level becomes “H”. R16, C6 and
C7 are noise filters. This circuit has an automatic sensitivity adjustment function to control the unevenness of the sensor sensitivity. Uneven sensor sensitivity is corrected by controlling the machine to have
a constant PTR voltage when there is no original. The intensity of the infrared light emitted from the
LEDs is changed to adjust the PTR voltage.
When the sensor sensitivity adjustment mode is selected, the PTR output voltage (analog value) is
measured by the A/D input terminals of the CPU (scanner side). The D/A output voltage of the CPU is
changed to keep the PTR output voltage to a certain level, and the LED current is adjusted by a voltage-current conversion circuit consisting of IC4, R29, Q5, etc. Each machine has a different D/A output
voltage value, which is stored in the volatile memory.

This circuit controls the inrush current flowing into the current regeneration capacitors (C23, C76 and
C40) mounted on the drive circuits for the read motor and reverse motor to a certain value. The circuit
consists of a posister (PTH1) which controls the current and FET (Q14) which supplies the current in
normal conditions.
Base current is not supplied to Q8 and it becomes OFF after the RADF opening/closing switch and jam
access cover switch are turned OFF until the cathode voltage of ZD2 reaches the zener voltage. At this
time, both voltages are set by R111 and C53. Q14 is turned OFF correspondingly to supply the current
to PTH1.
When the cathode voltage of ZD2 exceeds the zener voltage after the time allowance given by R111
and C53, a base current is supplied to Q8 to turn it ON and Q14 comes ON correspondingly. The current limitation is canceled and the current flowing in the PTH1 starts to be supplied to Q14.
R74 is discharge resistor to capture charge stored in consisting C23, C76 and C40 right after either of
the RADF opening/closing switch or jam access cover switch is opened. The circuit consisted of D2 and
PTH2 captures the charge stored in C53 right after either the RADF opening/closing switch or the jam
access cover switch is opened, and also controls inrush current for instantaneous opening/closing of
the cover.

This circuit controls the rotation, stoppage, rotation direction, excitation mode and motor current of the
read motor.
A drive clock signal (READ_CLK) and rotation direction signal (READ_CWB) are input to control the
speed and direction of the motor rotation. When the CPU judges the level of the enabling signal is “L”,
Pin16 - IC10 (READ_EN) becomes “L” level and turns OFF all the outputs from the drive IC regardless
of the state of other signals.
The output voltage of the D/A converter is separated at R85 and R105, and input into Pin10 - IC10 to
set the motor current value. The motor current value can be changed by altering the D/A output voltage.

10.7 Drive Circuit for Reverse Solenoid
This circuit controls the opening/closing of the flapper of the reverse solenoid.
When the level of RKNSOL_PWM is “H”, Q13 is turned ON and the flapper is closed. The drive signal
for the solenoid is a PWM signal. The flapper is closed in the maximum torque of the solenoid and the
duty value becomes 100% when the flapper is started to be closed. The duty value is then decreased
down to 50% and the flapper is kept closed while the temperature rising of the solenoid is lowered.

10.8 Reset Circuit
This circuit generates a CPU reset signal when the power is turned ON and the power voltage is cut off
or lowered instantaneously. This circuit has a watchdog timer for diagnosis of the CPU system operation.
The level of Pin8 - IC8 (*RES) is normally “H” after the power is turned ON. However, when the power
is turned OFF or the voltage of the +5 V power supply is decreased to 4.2 V or lower for some reason,
the level of Pin8 - IC8 becomes “L” and the CPU is reset. A clock with a fixed cycle is input to Pin3 - IC8
(CK) from the CPU to clear the watchdog timer of IC8. If the clock is not input from CPU due to a system error, the level of Pin8 - IC8 becomes “L” to reset CPU and system operation is stopped.

10.9 EEPROM Circuit
This circuit is an EEPROM to store ADF data and its peripheral circuit.
IC12 is a memory to store the adjustment value for reflection-type sensors, and data are sent/received
between IC12 and CPU using a 4-line type serial interface. Data saved in the IC12 is not erased even if
the power is turned OFF.
Pin1 - IC12 (CS) is a chip selection terminal and its level is “H” when data are being sent/received.
Pin2 - IC12 (CLK) is a serial clock terminal, and the serial data are sent in synchronization with the
clock input which is input to this terminal.
Pin3 - IC12 (DI) is a input terminal for serial data and Pin4 (DO) is an output terminal for serial data.

Note:
When black streaks still appear even if the ADF original glass is cleaned (e.g. in case the stain
adheres and cannot be removed), shifting the carriage position during scanning from RADF
(Adjustment Mode 05-359) is one of the solutions. Make sure to perform “RADF leading edge
position adjustment” (05-365 and 05-366) after the setting value of 05-359 has been changed.
When the setting value of 05-359 has been changed, the brightness of the copied image
changes accordingly. Change the setting value along with checking the copied image. (The
range of the recommended setting values is within ±10 bits.)
