The printer supplies DC + 27 V to the cutter motor to rotate the cutter motor and clutch counter clockwise.
The arm swings like a pendulum and moves the fixed slide cutter up and down to make a cut.

After making a cut, the arm turns the micro switch off and the cutter home position is detected.
When the cutter does not return to the home position because of a paper jam, an error occurs and the
