    摘要： A striker bar assembly includes a striker bar body having a recess at each of its opposite ends opening through top, bottom and end wall surfaces. The striker bar body has a flat impact surface perpendicular to the top and bottom surfaces. Generally T-shaped end members have legs for disposition in the striker body recesses. The wall surfaces of the striker body and legs of the members are spaced to provide a gap into which dampening material is provided. The gaps at each end of the striker bar assembly are of identical width in a front-to-back direction.

    摘要： A paper shear includes a flat disk with unsharpened edges pivotally mounted on an assembly carried by the printer carriage. The paper shear is pivoted between paper shearing engaged and disengaged positions relative to a shear platen. The mounting assembly includes a linear actuator and a mounting plate cooperable to pivot the paper shear into the engaged position at an extreme end of carriage travel and maintain it in the engaged position upon movement of the carriage in the opposite direction to shear the paper. The actuator and plate are then relatively displaced at the opposite extreme end of travel to pivot the paper shear into its disengaged position, whereby printing can be resumed.

    摘要： A printer has one or more tractor sets for continuously feeding paper along first and second paper paths. One tractor set may be pivoted between positions for feeding paper from the front or bottom of the printer along the first paper path. Where one tractor set is used, it may be removed from the first feed path and disposed along the second paper path to feed paper along the second paper path for printing. Where two tractor sets are provided, the second set is disposed along the second paper path to feed the paper along the second path for printing. The tractor sets are detachable and usable in each of the three tractor set feed positions. Other features include eccentric bearings, resilient roller assemblies, an integrally molded mainframe and a cartridge assembly having a one-way ribbon advance clutch and a tensioning device before the mobius loop.
