摘要： A liquid ejection apparatus includes: a head having ejection-opening groups and ejection-passage groups; caps for covering the respective ejection-openings groups; and suction passages connecting between the interiors of the respective caps and a sucking device. A method of manufacturing the liquid ejection apparatus includes: a step of classifying, as a first group, an ejection-opening group corresponding to an ejection-passage group having a resistance value not less than a first value and classifying, as a second group, another ejection-opening group corresponding to an ejection-passage group having a resistance value less than the first value; and a step of assigning at least one suction passage having a resistance value less than a second value to the ejection-opening group as the first group and assigning another at least one suction passage having a resistance value not less than the second value to the ejection-opening group as the second group.

摘要： There is provided an ink cartridge including a first ink chamber, a second ink chamber, an ink-flow check portion and a pressure control portion. The first ink chamber is configured to store ink therein. The second ink chamber is in fluid communication with the first ink chamber via a first path, the second ink chamber defining therein a volume. The ink-flow check portion is configured to allow the ink to flow from the first ink chamber to the second ink chamber and block the ink from flowing from the second ink chamber to the first ink chamber. The pressure control portion is configured to control an internal pressure of the second ink chamber.

摘要： An ink cartridge includes a case including an ink chamber configured to store ink therein, and a particular face facing an exterior of the case and having a first opening formed therethrough. The ink cartridge also includes an ink supply portion extending from a particular portion of the particular face in a particular direction, in which the particular portion surrounds the first opening, and the ink supply portion has a tube shape. The ink supply portion includes a particular chamber formed therein, an end wall having a second opening formed therethrough, and a peripheral wall extending from the end wall. The ink supply portion is configured to supply ink from the ink chamber to the exterior of the case via the particular chamber and the second opening. Moreover, the ink cartridge includes a plurality of protrusions. Each of the plurality of protrusions extend from the peripheral wall in a corresponding radial direction with respect to the peripheral wall, and extends in an axial direction of the peripheral wall. Each corresponding radial direction is perpendicular to the axial direction of the peripheral wall, and the axial direction of the peripheral wall is parallel to the particular direction. Moreover, each adjacent pair of the plurality of protrusions defines an ink holding space therebetween, and the ink holding space has a first end and a second opposite the first end, in which the first end is positioned closer to the end wall than the second end is positioned to the end wall, and the ink holding space is open at the first end.
