Abstract:
An ink jet printer system, comprising:a. an ink jet printhead having a drop generator and a catcher located adjacent to the ink drop generator; b. an eyelid for sealing against the catcher to contain ink within the printhead on startup and shutdown of the printer system; c. an eyelid actuator assembly means for moving the eyelid into a sealed position for startup and shutdown and into an open position so that ink jets comprised of ink drops can exit an array of orifices and pass between the catcher and the eyelid to print on a print media; and d. at least one alignment flexure means for precisely positioning the eyelid relative to the catcher or the drop generator during assembly of the printer system, wherein the at least one alignment flexure means remains essentially rigid during the actuation of the eyelid.
