    摘要: Provided is a leak tester for a carrier for printhead integrated circuits. The carrier has at least one fluid inlet in fluid communication with a plurality of fluid outlets via discrete fluid paths. The tester includes a support assembly that includes at least one receptacle shaped and configured to receive at least one respective carrier, and a pressurized fluid supply arranged on the support assembly and configured to supply pressurized fluid to the fluid inlets, the pressurized fluid supply incorporating a sealing mechanism configured to engage the fluid inlets in a sealing manner. The tester also includes a pressure measurement arrangement operatively arranged with respect to the pressurized fluid supply to measure pressure applied at the fluid inlets, and a controller operatively connected to the pressure measurement arrangement and pressurized fluid supply, the controller being configured to control the fluid supply to charge the carrier with pressurized fluid until a predetermined pressure is reached, and to monitor the pressure for a predetermined period of time.

    摘要: A printhead maintenance station (20) for maintaining a printhead (5) in an operable condition is provided. The maintenance station (20) comprises an elastically deformable pad (6) having a contact surface (7) for sealing engagement with an ink ejection face (8) of the printhead (5). The maintenance station (20) also comprises engagement mechanism (25) for moving the pad (6) between a first position in which the contact surface (7) is sealingly engaged with the face (8), and a second position in which the contact surface (7) is disengaged from the fac (8). The maintenance station (20) is configured such that the contact surface (7) is progressively contacted with the face (8) during sealing engagement and peeled away from the face (8) during disengagement.

    摘要: There is provided an ink pressure regulator for regulating a hydrostatic pressure of ink supplied to an inkjet printhead. The regulator comprises: an ink chamber having an ink outlet for fluid communication with the printhead via an ink line; an air inlet; a regulator channel having a first end communicating with the air inlet and a second end communicating with a headspace of the chamber, the second end defining a bubble outlet; and a wetting system for maintaining at least some liquid in the regulator channel, thereby ensuring that air entering the headspace first passes through the liquid. The wetting system comprises a first wetting chamber connected to the first end, a second wetting chamber connected to the second end, and a liquid-retaining structure positioned in the second wetting chamber. The regulator channel, the first wetting chamber, the second wetting chamber and the liquid-retaining structure are all in fluid communication with each other. The regulator channel is dimensioned to control a Laplace pressure of air bubbles drawn from the bubble outlet as result of supplying ink to the printhead, thereby regulating a hydrostatic pressure of the ink.
