    Abstract: A system for an ink delivery system comprises a feed path having an insertion end and a melt end, and an ink stick transport for moving at least one ink stick between the insertion end and the melt end of the feed path. At least one sensor is positioned along the feed path. A controller is configured to actuate the transport to move at least one ink stick in a first direction from the insertion end toward the melt end of the feed path so that a coded sensor feature of the at least one ink stick actuates the at least one sensor to generate a signal. The controller is configured to actuate the transport to move the at least one ink stick in one of the first direction and a second direction toward the insertion end of the feed path in response to the signal.
