Perforation cutter motor
As shown below, the perforation cutter is secured to the belt which runs between the
front and rear sides of the printer. When the cutter motor rotates this belt, the cutter
reciprocates.

Perforation Cutter Motor
When the High level cutter motor signal (start instruction) and High level cutter
motor rotation direction signal (rearward direction instruction) are asserted while the
cutter is in the home position (front side), the cutter motor is activated to move the
cutter rearward. When the cutter is detected by cutter sensor 1, the cutter motor signal
goes Low to stop the motor. When the High level cutter motor signal and Low level
cutter motor rotation direction signal (forward direction instruction) are asserted, the
cutter moves forward until it is detected by cutter sensor 0. To operate the cutter, the
cutter solenoid (CSL) turns ON and the paper retainer actuates.
