  • Patent number: 10562308
    Abstract: A jumper is configured to replace a printhead connected to an ink delivery system to enable a controller operating the ink delivery system to prime the ink supply conduit and the ink waste conduit of the ink delivery system. The jumper includes a pressure impedance element that simulates a pressure drop across the printhead when the printhead is connected to the ink delivery system. The jumper enables the ink supply conduit and the waste ink conduit to be primed with reduced risk of air being urged into the inkjets of the printhead once the printhead is reconnected to the ink delivery system.
