DC Jack: |
Plug the AC adapter or DC output plug of the power supply. |
|
d |
Power switch: |
When this Power switch is turned ON, power is supplied to the board |
|
|
|
|
and initializing operation starts. |

Connector for mechanism |
Connected to MD910 (24 digits) or MD911 (40 digits). |
|

connection (CN2): |
|
|
f |
Connector for operation |
Connected to the operation panel. For the functions, refer to the |
|
|
panel (CN4): |
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. |

Connector for winder |
Connector for connecting Winder (for controlling the motor for auto |

paper winding device) (Option) |
i |
Connector for Interface |
Either parallel or serial connector is present depending on the board |
|
(CN3): |
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.
