THEORY OF OPERATION
2.4.2 Print Head Carriage Mechanism
This print head carriage mechanism consists mainly of the carriage, carriage motor, gear train, home position detector, and timing detectors. When the carriage motor rotates, the drive shaft (cylindrical cam) is rotated by the reduction gear. The print head supported by the carriage moves right and left. The print head position is determined by timing signals generated by the timing detectors and the home position signal generated by the home position detector.
