Abstract
An ink priming system for a cartridge includes a priming inlet provided on a pagewidth printhead assembly, the priming inlet including a valve incorporating an elastomeric seal; an ink flow passage providing fluid connection between the pagewidth printhead assembly and an ink storage compartment of the cartridge, the ink flow passage terminating at the ink storage compartment to form an ink outlet; an ink filter provided across the ink outlet; a vent hole defined through a surface of the ink storage compartment, the vent hole being defined through a surface opposite the ink outlet; and an ink retaining member provided within the ink storage compartment for receiving and storing ink, the ink retaining member being interposed between the ink outlet and the vent hole. Ink is supplied to the priming inlet of the pagewidth printhead assembly to flow from the pagewidth printhead assembly into the ink storage compartment via the ink flow passage and across the ink filter. The ink received via the ink flow passage primes both the printhead assembly and the ink retaining member of each ink storage compartment with ink substantially simultaneously.
