Beschreibung
Zusammenfassung:	A system for performing a carrier return operation in a typewriter, printer, etc., having a leadscrew controlled carrier, and controlling when the carrier is to be returned dependent upon a carrier return signal generated in conjunction with combinations of generated signals indicative of rotation and non-rotation of the leadscrew, and the leadscrew rotational position. The system is structured such that the carrier will be returned and properly positioned at the left margin or starting line upon termination of escapement, and upon signals being generated indicating that the leadscrew is in its home rotational position.
