Abstract: In a printer that uses a prithead (22 min ) with multiple electrodes (56) for supplying current to a ribbon (24 min ), the electrode voltage levels for a plurality of non-adjacent electrodes are combined to provide a resultant voltage level that is examined in threshold detector (72) to detect abnormalities. By so combining voltages, insignificant excursions in electrical characteristics as might result from minor ribbon imperfections are generally eliminated from the triggering of a shutdown response, while still retaining a rapid response for preventing further heat generation in those situations where a serious ribbon failure has occurred.

Abstract: Printhead assembly for a printing mechanism of the kind that swipes a printhead (109) along a ribbon (116) in producing marks on a receiving medium (106) mounted to pivot and includes a ribbon guide (36) that serves to wrap the ribbon around the trailing side of the printhead (10). The assembly is positioned to permit the printhead (10) to be rotated to a normal printing position at a printing line. By so arranging the ribbon path that the ribbon directions for arrival and departure of the assembly intersect the pivot axis, essentially zero resultant torque may be applied to the assembly by ribbon tension forces and the printing pressure at the receiving medium is, accordingly, unaffected by ribbon tension variations.
