Abstract
In a matrix print head, a plurality of elongated printing elements, mounted in a frame, are driven axially by electromagnetic means to effect printing on record media positioned adjacent to the printing ends of the printing elements. A dampening element, of generally conical configuration, is centrally disposed in the frame, within the volume defined by the plurality of printing elements, in order to dampen the bending and vibration of the printing elements, and thus reduce or eliminate consequent fatigue failure.
