摘要： A printhead purging system comprises an ink conduit for supplying ink to a printhead, a hammer head for hammering a wall of a compressible part of the conduit, a spring-loading mechanism for priming the hammer head, and a release mechanism for releasing the primed hammer head. Release of the primed hammer head compresses the ink conduit and results in purging of ink from the printhead.

摘要： An inkjet printer has an inkjet printhead and a printhead maintenance station. The maintenance station includes a maintenance roller which is rotatable and moveable between a first position in which a capping portion is sealingly engaged with the printhead and a second position in which the capping portion is disengaged from the printhead. The maintenance roller is mounted on a chassis which is reciprocally moveable between the first and second positions. The printer includes an engagement mechanism for moving the chassis between the first and second positions by complementary engagement with engagement formations on the chassis.

摘要： An inkjet printer includes a printhead integrated circuit (IC) with an array of nozzles for ejecting ink on to print media; an ink supply reservoir for storing ink; an ink supply line defining a flow path from the ink supply reservoir to the printhead IC; a valve in the ink supply line proximate the printhead IC selectively closing the flow path to the printhead IC; an ink purge actuator for forcing a volume of ink out of the printhead under pressure; a printhead maintenance system having a collection roller for rotating such that the collection roller surface collects ink purged from the printhead and draws the ink away; and a pressure regulator provided in the ink supply reservoir downstream from the ink supply reservoir. The pressure regulator is normally biased shut, and operable to open upon a threshold pressure difference between ink upstream of the pressure regulator and ink downstream of the pressure regulator.

摘要： An inkjet printer that has an ink supply, an ink manifold in fluid communication with the ink supply, a printhead IC with and array of ink ejection nozzles mounted to the ink manifold, a pump in fluid communication with the ink manifold and, a gas inlet that can be opened to establish fluid communication between the ink manifold and a supply of gas, and can be closed to form a gas tight seal. The ink manifold can be primed using the pump by closing the gas inlet, and de-primed when the gas inlet is open. This allows the printhead to be deprimed during storage and transport and it allows the printhead IC to be cleaned by a foam formed by air forced through the ink election nozzles.
