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 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 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： In the case of printing in three-value level utilizing two kinds of inks mutually different densities for one color (higher and lower density inks), it is assumed that a reflection density of a region having a predetermined area when solid print is performed only by the lower density ink, and that when solid print is performed only by the higher density ink are expressed ODt and ODn, respectively. Since the granular appearance of the ink dots is expressed in terms of reflection density of one dot, the granular appearance of a lower density ink dot at a portion of image formed only by the lower density ink dots and the granular appearance of a higher density ink dot at a portion of image formed by the higher and lower density ink dots are expressed in terms of values of ODt and (ODn-ODt) divided by the number of pixels included in the above region, respectively. Accordingly, by making the reflection density ODt to be approximately one half of the reflection density ODn, the granular appearance produced by the lower density ink dot at the highlighted portion and the granular appearance produced by the higher density ink dot at the portion where the higher density ink dots scattered in the lower density ink dots can be made substantially equal to each other. For this purpose, it is preferable that a dye concentration of the lower density ink is to be about one fourth of that of the higher density ink.

摘要： It is checked whether an ink used in a printhead has a high density. The type of a printing medium used for a print operation is also identified. An image is printed by scanning the printhead once or a plurality of times. When a print operation is to be performed by using a thick ink, an image is printed by using mask data and the driving frequency of the head which are set for the thick ink. When a print operation is to be performed by using a thin ink, an image is printed by using mask data and the driving frequency of the head which are set for the thin ink and the type of printing medium used for the print operation. Codes of the respective color data of print data are determined in accordance with the types of inks used for a print operation, and an image is printed by printing a plurality of dots or dots in an overlapping state by the multi-pass method.

摘要： Print codes supplied from a host computer are received and analyzed to generate print data for the individual colors, and the generated print data are stored in print buffers corresponding to the colors. The print data corresponding to yellow ink with high lightness is expressed by binary data, and is printed by one dot per pixel by a single print scan. The print data corresponding to each of the remaining high-density (thick) inks is expressed by multi-valued data having a larger number of bits than the yellow data, and is printed by a plurality of print scans.
