3.2. Connector for Power Supply

Connector used: CN1: MOJ-D14 (Iizuka Electric)

Electrical Specifications

Input volt a ge: 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 val u e is at temperature of 25 °C a nd normal humid it y.
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 co nnecting or discon ne cting a connecto r, make sure the prin ter power is turned off.

2. Always use t he power voltage with i n the specified range.

Caution

• When the power supply other than specified is used, bad effect may occu r on printing operation, etc.
When the printer is operated continuously, electronic components in the board may generate heat. Use

the printer pa ying ful l at tent io n to heat dissi pat io n.

• When the power supply with insufficient peak current is used, degradation of print quality may occur
dependi ng on the printing st ate.

• Be sure to prepare for easy tur ni ng off the power sup ply in ca se of power failu re.

• Power supply with var ious kinds of protect ive circui ts such as ove rvolta ge protec tion and ove rcurrent

protection is recommended.

• If any abnormality such as abnormal odor is sensed during operation, turn the power supply off
quickly.
