Abstract: A ribbon lift guide for a serial printer comprising a generally circularly shaped flexible disc member coupled to the hub of the print wheel element on the side of the print wheel containing the print surface of the character slug and positioned parallel to a plane formed by the spokes. The ribbon lift guide has a radius less than the distance from the center of the hub to the closest point on the print surface of the character slug. The guide is mounted coaxially with the print wheel to guide the ribbon during ribbon lift operation.

Abstract: A print wheel mounting assembly for a daisy type print element comprising a generally circular disc section coupled to the hub of the print element, a generally cylindrical section, an end cap section pivotally coupled to the cylindrical section and having a shaft portion extending at right angles therefrom and back toward the hub of the print element and a coil spring positioned around the generally cylindrical section with the end portions positioned such that when the shaft portion of the end cap is inserted therebetween, the coil spring is tightened around the generally cylindrical portion to clamp the print element firmly to the shaft of the print element motor.
