cDC Jack: Plug the AC adapter or DC output plug of the power supply.
dPower switch: When this Power switch is turned ON, power is supplied to the board
and initializing operation starts.
eConnector for mechanism
connection (CN2): Connected to MD910 (24 digits) or MD911 (40 digits).
fConnector for operation
panel (CN4): Connected to the operation panel. For the functions, refer to the following descriptions.
a) POWER lamp: Lights when the Power switch is set to ON and goes off when the
Power switch is set to OFF.
Blinks while memory switch is set or at the occurrence of memory
error.
b) SEL lamp: Lights when this board is in the Select (online) state and goes off when
it is in the Deselect (offline) state. Printing occurs only when this lamp
is ON.
1) Blinks at intervals of 0.5 s at the occurrence of Paper End.
Goes off when the SEL switch is pressed after paper is set.
2) Blinks at intervals of 1/4 s at the occurrence of Alarm state
(blinking state) due to the cause other than Paper End. This lamp
goes off when the SEL switch is pressed after removing the cause
of the alarm or when printer power is reset.
c) LF switch: Pressing this switch causes a paper feed (only in Deselect state).
This switch is used when loading a paper or when using a space.
d) SEL switch: When this switch is pressed, this board is set to the Select (online)
state. Pressing this switch again causes the board to be set to the
Deselect (offline) state. This switch is also used when removing the
alarm state. When the printer is set to the Deselect state, all data, if
present in the input buffer, is printed.
gConnector for Paper Near
End sensor (CN5): Connector for Paper End (paper detection)

hConnector for winder
(CN6): Connector for connecting Winder (for controlling the motor for auto paper winding device) (Option)
iConnector for Interface
(CN3): Either parallel or serial connector is present depending on the board type.
Connects to each host through a cable. Before connecting the
connector, make sure the host and board are powered off.
3.2. Connector for Power Supply
Connector used: CN1: MOJ-D14 (Iizuka Electric)
Electrical Specifications
Input voltage: 7 to 15 V DC
Current at non printing: 0.15 A average
Current at printing: 0.80 A average (approx. 7.5 A at peak)
The above value is at temperature of 25°C and normal humidity.
Average current is the value with print rate of 12.5%.
The values vary with the printing condition, environment of use, operating conditions, etc.
Precautions
1. Before connecting or disconnecting a connector, make sure the printer power is turned off.
2. Always use the power voltage within the specified range.
Caution
•When the power supply other than specified is used, bad effect may occur on printing operation, etc.
When the printer is operated continuously, electronic components in the board may generate heat. Use
the printer paying full attention to heat dissipation.
•When the power supply with insufficient peak current is used, degradation of print quality may occur
depending on the printing state.
•Be sure to prepare for easy turning off the power supply in case of power failure.
•Power supply with various kinds of protective circuits such as overvoltage protection and overcurrent
protection is recommended.
•If any abnormality such as abnormal odor is sensed during operation, turn the power supply off
quickly.

6 GND — GND
Caution
(1) For the POWER and SEL LEDs, a resistance of 330 Ωis provided at the circuit side to adjust the
current to 10 mA. Use the LED with forward voltage of about 2 V. Do not use LED exceeding 10
mA. Otherwise, the control may be damaged.
(2) The input terminals for LF-SW and SEL-SW have the above circuit. Though a ceramic capacitor is
inserted in the circuit for preventing chattering, large chattering may occur depending on the switch.
(3) Apply insulation processing to the terminal not in use to prevent the end of the cable from contacting
other terminal or parts.

3.5. Connecting Paper Near End Sensor
Connector used: CN5: 5267-03A (Molex)

When using switch Sensor Paper
* The above circuit is an example of reflection type photo interrupter.
When using the above sensor, allow a clearance of approx. 1 mm from paper.

As the sensor used is different in electrical characteristics, use the sensor after fully recognizing it.
* The voltage detection range of the board (between 2 and 3) is as follows:
0 to 0.4 V: With paper
1 V or more: Without paper
Detection status other than the above is out of warranty.
3.6. Connecting Winder
Connector used: CN6: B2B-XH-A (JST9
Set up the connection shown in the following figure.
Voltage for the winder motor is applied at the same timing as that for the motor for printer mechanism.
Printing deviation may be caused by the torque of winding.
