Abstract: An air removing device is connected to a tank to contain ink through a first supply tube, and an ink-jet head is connected to the air removing device through a second supply tube. The first supply tube and ink-jet head are heated and controlled. Air dissolved in ink is sucked out through a hollow fiber membrane provided in a housing by operating a vacuum pump by supplying ink to the hollow fiber membrane while heating and controlling atmosphere in the housing. Thus, air dissolved in ink is removed, and ink heated to a temperature suitable for ejection is supplied to the ink-jet head.

Abstract: An ink jet recording apparatus having an ink jet head to discharge supplied ink from a nozzle, a deaeration device to deaerate dissolved gas from the ink supplied to the ink jet head, an ink reservoir, provided in an ink channel between the deaeration device and the ink jet head, to apply negative pressure by a difference in level of the ink reservoir surface and the nozzle, and a preventative member, floated on the surface of ink in the ink reservoir, to prevent contact between the ink and air. Even when the ink, from which dissolved gas has been deaerated by the deaeration device, is stored in the ink reservoir in a course of supplying process of the ink, re-dissolution of gas in the ink in the ink reservoir can be suppressed. Further, the ink can be reliably pressurized in the ink jet head, and ink droplets can be excellently discharged from the nozzle.

Abstract: In an ink jet recording apparatus having two head units, each having a large number of ink nozzles arranged in a line, assembled so that they overlap with each other, an 8-shade image signal is entered into a correction circuit and a line direction position signal is input into a position signal decision circuit. When the position signal decision circuit decides that the position signal represents the overlapping zone of the head units, the shade level of the image signal is divided between the head units. For example, when the shade level of the image signal is 7, one of the head units is allotted the shade level and the other is allotted the shade level. The overlapping nozzles in a pair eject droplets of ink to form one dot.

Abstract: An ink jet head is provided having ink chambers, energy-generating elements provided in the ink chambers, respectively, and ink outlet ports communicating with the ink chambers, respectively. The ink jet head may be left unused for a time longer than a predetermined time, with a meniscus formed in each ink outlet port. In this case, a drive pulse is applied to each energy-generating element several times, thereby forcing the ink outwards from the ink outlet ports and increasing a surface area of the ink from a surface area of the meniscus. Then, a negative pressure is applied in each ink chamber, thereby drawing the ink back toward the ink chambers, thus forming a meniscus again in the ink outlet ports. In this condition, a drive pulse is applied to the energy-generating elements, thus ejecting an ink droplet from the ink outlet ports to record data.

Abstract: An ink-jet head includes a nozzle array including plural nozzles. The nozzle array has a first nozzle group arranged in the center thereof and second nozzle groups arranged further on outer sides than the first nozzle group. Inter-nozzle pitches of the second nozzle groups are larger than inter-nozzle pitches of the first nozzle group. A direction in which nozzles of the second nozzle group eject an ink and a direction in which nozzles of the first nozzle group eject the ink are different.
