8-1-8 Electrical specifications

8-1-8-1 The explanations of the circuit operations

1)Head Carriage Step Motor

-It rotates and moves the Dot Head by using the several gears and synchronous belt

-Print Speed : 4.6 Line/Sec

-This step motor is control by constant current method. So, current flows two red line of step motor is Max.560㎃

-This step motor is control by SMA7029M (Recommended)

2)Paper Feed Step Motor

-It is used when the paper is fed.

-The characteristics of step motor is as same as head carriage step motor

3)Home Sensor

-It detects the head position

-It decides the start point of printing

4)Solenoid

-It plays part in exchanging printing color (red → black)

5)Head

-It plays part in printing a character (Axiohn Co.)
