Abstract
The present invention provides a bi-directional drive printer actuator with position feedback control and methods of operation to optimize the performance of impact type printers. By monitoring the position of the print wire, a forward input power pulse can be varied as to magnitude and duration to maintain a desired predetermined velocity of the print wire up until the time of impact. Further, by monitoring position feedback signals generated as the print wire returns to an at-rest position, a reverse input power pulse and forward input power pulse can be modulated for magnitude and duration to maintain a desired rearward velocity of the print wire, and bring the print wire to an at-rest position with a minimum of rebound off a back stop.
