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.
