ABSTRACT:
A machine for re-inking printing ribbons for line printers and the like includes a pair of spaced apart spool mechanisms which receive the supply and take-up spools of the ribbon. Disposed between the spool mechanisms is an inking roller which is partially submerged in an ink tank. Adjacent to the tank is a light source and light pipe assembly for detecting holes in the ribbon to be inked. The device accommodates ribbon spools of differing lengths, and is also provided with a ribbon edge sensor which controls the axial position of the ribbon as it is wound onto one of the spools. The spool mechanisms drive the ribbon past the hole detector in one pass, and a pressure roller urges the ribbon onto the inking roller in another pass to re-ink the ribbon.
