Abstract: The disclosure describes a passive lubrication system for use in a high speed print hammer mechanism to provide continuous lubrication to all print hammer elements. Channels are formed along the length of a pivot pin and filled with a porous material having a finer porosity than the sintered print hammer block serving as the principal reservoir. Fins located at each side of print hammer elements also are of the same porosity as the print hammer block and communicate lubricant to the material in the pivot pin channels. From the channels, lubricant is conveyed to the interface between each print hammer element and the pivot pin by capillary action.
