This article describes a ribbon shield device which prevents ribbon lift, ribbon foldover and ink smear on continuous paper forms. The device accomplishes this by eliminating as much contact as possible between the inked ribbon and the continuous forms. The printing device utilizing the structure of the present disclosure is a wire matrix printer with a lateral moving printing device and a solid stationary platen. The gap between the printhead and the platen is necessarily close, due to the limited stroke of the print actuators. For this reason, it is necessary to introduce a thin film between the print actuator carrier and the platen. The limited thickness of this thin film does not provide adequate support for itself when mounted in the machine.
