摘要： A capping assembly includes a capper having a perimeter seal for sealing engagement with the printhead. The capping assembly has an enclosed capping volume when the capper is sealingly engaged with the printhead, whereby the capping volume is variable in response to relative differences in pressures inside and outside the capping volume.

摘要： An inkjet printer includes a printhead having first and second ports; an ink container for supplying ink to the printhead, the ink container having a supply port and a return port; a first ink conduit interconnecting the supply port and the first port; a second ink conduit interconnecting the return port and the second port; an ink valve positioned in the first ink conduit; a first pump positioned in the second conduit; and a second pump positioned in a valve bypass conduit. The first and second pumps are employed during pressurized priming of the printhead so as to optimize a pressure gradient along a length of the printhead.

摘要： An ink tank for an ink delivery system includes: a housing having an ink inlet port and an ink outlet port; an air vent communicating with a headspace of the ink tank; a filter positioned in the housing for filtering ink supplied from the ink tank via the ink outlet port; and a baffle plate positioned in the housing between the ink inlet port and the filter. The baffle plate is configured for directing air bubbles entering the ink tank via the ink inlet port towards the headspace of the ink tank. A baffle opening is positioned towards a base of the ink tank, thereby allowing ink to flow from the ink inlet port towards the ink outlet port via the baffle opening.

摘要： An ink tank for an ink delivery system includes: a first ink chamber having an ink inlet port and an ink outlet port; a second ink chamber positioned above the first ink chamber and having a roof defining a tortuous vent pathway open to atmosphere via a gas port; and a diffusion tube interconnecting the first and second ink chambers. The first ink chamber has a smaller volume than the second ink chamber and the diffusion tube minimizes diffusion of air from the second chamber to the first chamber.

摘要： A method of de-aerating a filter chamber includes the steps of: providing a filter material positioned in the filter chamber between a filter inlet port and a filter outlet port; providing a liquid at the filter inlet at a positive hydrostatic pressure; and venting air bubbles from the filter chamber to atmosphere via a closed vent chamber connected to a vent port of the filter chamber. The vent chamber has a wall formed of an air-permeable polymer.
