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.
