5-9. Printer drive circuit
When CPU wants to rotate the mortor, CPU outputs “Motor” signal (L
➔
H), and Motor signal goes
through the motor drive circuit and then it become “L”.Then Motor rotates because of difference voltage
between Motor and Motor COM TERMINAL.
Head drive signal is same as Motor drive.
