  • Servo control system for carriage of matrix printer
    Patent number: 4459050
    Abstract: A servo control system for the carriage of a matrix impact printer allows printing to occur during both acceleration and deceleration of the carriage. This is especially useful where the carriage is transporting several ribbon cartridges of different colors. In addition, printing may occur during the midrange portion of the carriage which is driven at a variable velocity to compensate for differences in printing and resolution requirements.
