    摘要: A method for preserving a liquid-ejection head is disclosed. The method uses the liquid-ejection head having a first liquid-flowing passage that receives a supply of a first liquid and communicates with an ejection port; a second liquid-flowing passage that receives a supply of a second liquid that differs from the first liquid; a bubble generation area formed on the second liquid-flowing passage for heating the second liquid to generate a bubble in said second liquid; and a movable member positioned between the bubble generation area, having a free end on an ejection port's side of the first liquid-flowing passage and a supporting end on other side of the first liquid-flowing passage, where the free end of the movable member is displaced toward the first liquid-flowing passage by a pressure caused by a generation of the bubble when said second liquid is heated. The method includes a step of performing a replacement of one of the fist liquid and the second liquid with the other at least at a periphery of the ejection port or a periphery of the movable member. Thus the liquid-ejection head is able to perform an excellent recording whether it has not been used for a long time.

    摘要: An apparatus uses a liquid ejection head including a first liquid passage communicating with an ejection port, a second liquid passage separated from the first liquid passage by a separation wall, and a movable member formed as a part of the separation wall. In the second liquid passage, a thermal energy generation device is arranged at a position opposing to the movable member. The movable member has a free end portion and a fulcrum. Recovery of the first and second liquid passages is performed by suction and/or pressurization. Upon recovery by discharging the liquid in respective liquid passage having higher flow resistance, the pressurizing force and/or the suction force for the liquid passage having higher resistance is set to be greater that the pressurizing force and/or the suction force for the other liquid passage having lower flow resistance.

    摘要: A liquid jet head is provided with discharge ports for discharging liquid, liquid flow paths conductively connected with the discharge ports, air bubble generating areas for creating air bubbles in the liquid, and movable members arranged to face the air bubble generating areas, each having a free end in a position relatively near to the discharge port with respect to a fulcrum thereof. This movable member is inclined to position the free end of the movable member to release the air bubble generating area partly to the discharge port so as to enable the tangential line of the free end of the movable member on the side of the air bubble generating area or the extended line thereof to reach directly the discharge port formation area having the discharge port on the liquid flow path side before the creation of air bubble on the air bubble generating area, and with this position as reference, the movable member is displaced following the creation of air bubble on the air bubble generating area. With this arrangement, the liquid discharging efficiency and speed are significantly enhanced as compared with the conventional liquid jet head, and due to more stabilized discharge of droplets from the discharge ports, the quality of recorded images is improved.

    摘要: An ink jet recording apparatus and ink jet recording method record using different kinds of ink each having the same series color and a different density. The jet recording apparatus includes a converting unit for converting an input image density signal into an output image density signal, a binary unit for converting the output image density signal into binary data, an inverting unit for inverting the binary data, and a distributing unit for the binary data inverted and binary data to be inverted to drive data for an ink discharge unit and drive data for another ink discharge unit. Density unevenness and texture which arise from an image process, particularly a binary process, can be prevented. Different kinds of ink, each of which has the same series color and a different density, are respectively scanned so as not to overlap on the same pixel. Density unevenness due to ink soaking can be suppressed because different kinds of ink each having the same series color and a different density are not shot at the same position.

    摘要: A method and an apparatus for ink jet printing use a print head including a first nozzle group for discharging a first ink, a second nozzle group for discharging a second ink and a third nozzle group for discharging a printability improving solution. The third nozzle group is displaced between the first nozzle group and the second nozzle group. The first nozzle group discharges the first ink on the printing medium based on image data to form an image, the third nozzle group discharges the printability improving solution on the image formed on the printing medium by means of another step, and the second nozzle group discharges the second ink on the image formed on the printing medium. The printability improving solution has higher penetrability into the printing medium compared to the ink.The method and apparatus can attain a clear colored, high density image without color mixing, which has high water resistance on plain paper, with a low running cost.

    摘要: This invention relates to an ink jet recording apparatus and a recording method for recording images of high dignity with the amount of ink placed per unit area of a recording medium being always kept constant even if the resolvability when recording is effected changes. When the amount of ink of an ink droplet discharged from a recording head is constant (25 pl), the average number of recorded dots conformity to the resolvability is found on the basis thereof, and the number of recordable dots is found from this average number of dots. The difference between this number of actually recorded dots and the average number of recorded dots is adjusted by reducing the value of recording data in advance.
