Abstract: Embodiments described herein provide ink recirculation capabilities for Drop-On-Demand (DOD) printing systems. One embodiment comprises a system that includes a controller, a DOD print head, an ink tank, an ink pump, and a recirculation cap. The ink pump transports ink from the ink tank to the DOD print head, and the recirculation cap captures ink ejected by the DOD print head. The recirculation cap also transports the capture ink to the ink tank. In response to detecting a start of an ink recirculation cycle, the controller collocates the recirculation cap proximate to nozzles of the DOD print head, and directs the DOD print head to begin ejecting ink through the nozzles into the recirculation cap for transport of the captured ink to the ink tank. The controller detects an end to the ink recirculation cycle, and directs the DOD print head to stop ejecting ink into the recirculation cap.

Abstract: System and methods for cleaning printheads and printhead wipers. One embodiment is an apparatus that includes a belt configured to rotate in a loop, and a wiper attached to the belt configured to wipe ink from a printhead. The apparatus also includes a tank configured as a reservoir for a cleaning solution, and a controller configured to drive the belt so that an end of the wiper drags across the printhead when in an upper portion of the loop and submerges in the cleaning solution of the tank when in a lower portion of the loop.
