摘要： An inkjet printer includes at least one head for ejecting ink in the form of droplets, the ink being supplied from an ink tank. The head includes: a plurality of nozzles; an interior flow passage for supplying the ink to the nozzles; and a pressure adjustment part. The pressure adjustment part is connected to the interior flow passage. The pressure adjustment part has a damper space filled with a fixed amount of gas. The gas in the damper space is in contact with the ink filling the interior flow passage. When a negative pressure is developed in the nozzles by the ejection of the ink, the gas in the pressure adjustment part expands, so that the negative pressure in the nozzles is rapidly relieved. This prevents outside air from entering the nozzles.

摘要： A technique is provided with which the concentration in liquid to be supplied to a liquid ejection apparatus is less likely to be uneven. A liquid container for supplying a liquid having a precipitating component to a liquid ejection apparatus includes: a liquid container; a liquid leading portion for leading the liquid in the liquid containing portion to the liquid ejection apparatus; a liquid flow tube that has a base end connected to the liquid leading portion, the liquid flow tube extending within the liquid containing portion from the liquid leading portion toward the second end; and a spacer member that is provided in the liquid containing portion and has a spacer body forming a liquid-retaining space for retaining the liquid in the liquid containing portion. The spacer member is coupled to the liquid leading portion. The liquid flow tube is coupled to the spacer member.

摘要： In one embodiment, a printing system includes a printhead module that has a printhead and a regulator chamber. The regulator chamber contains ink and a regulator air bag. The regulator air bag and the printhead are in fluid communication with the ink, and the printhead includes a plurality of ejection nozzles. The printing system includes a pressure source to inflate the air bag, thereby displacing an amount of ink sufficient to agitate menisci in the ejection nozzles without pushing ink out of the nozzles.

摘要： A container assembly may include a regulated tank to contain a fluid, a free tank to replenish the fluid in the regulated tank, a first expandable member between an interior of the regulated tank and ambient atmospheric pressure, a second expandable member between the interior of the regulated tank and an inflation port, a first valve to selectively connect the free tank to the regulated tank based upon a pressure differential between the interior of the regulated tank and an interior of the free tank and a second valve actuatable between an open state permitting an interior of the free tank to be pressurized and a closed state. The second valve is actuatable between the open state and the closed state based upon a position of the first expandable member.
