ABSTRACT:
A matrix printer, having a movable print head, a paper feed and advance mechanism and an ink ribbon system, is driven by two motors; one for the print head and one for paper feeding and ribbon movement. This second motor is a reversible one and drives the paper advance when rotating in one direction and the ink ribbon when rotating in the opposite direction. Speed control for the paper feed phase is derived from a cam on the input shaft for the paper advance. A reset mechanism for that shaft is also included.
