摘要： The present invention provides a liquid application device and an ink jet recording apparatus each capable of reducing deterioration in application quality due to an increase in the number of times of use of a roller, thereby improving durability. The present invention includes an application roller which applies liquid to an application medium, and a liquid retention member which retains the liquid in a liquid retention space formed by making the application roller be in contact with the retention member. With this structure, a pool of the liquid is formed, with rotation of the application roller, in an area upstream of a contact area, in a rotational direction, between the application member and the retention member at a side where a surface of the application member enters the contact area therebetween.

摘要： For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

摘要： A printing apparatus and a preliminary discharge control method are capable of efficient preliminary discharge control even in a case where a time interval to assure normal printing is equal or nearly equal to the period of one print scanning of an inkjet printhead. In the method, in an inkjet printhead which performs printing by discharging ink from plural print elements while being reciprocate-scanned by a carriage, the number of ink dischargings from each of the plural print elements is counted during print scanning by reciprocate scanning. It is determined whether or not the counted number of ink dischargings from each of the plural print elements is equal to or greater than a predetermined number at predetermined intervals. In accordance with the result of determination, a printable period is updated, and the updated printable period is compared with time necessary for the next print scanning upon completion of one print scanning by reciprocate scanning. Then, in accordance with the result of comparison, preliminary discharge is performed from the inkjet printhead.

摘要： The present invention provides a liquid applying apparatus and an ink jet printing apparatus which can reduce evaporation that may occur when a application liquid is left in a liquid holding member for a long time, the liquid holding means forming a space between an elastic member and a roller to hold the application liquid, the apparatuses also being capable of preventing the leakage of the liquid from the liquid holding member regardless of a variation in the posture of the apparatus. In collectitng the application liquid from the liquid holding member to a storage tank, the apparatuses switches a selector valve to allow an air communicating port and a tube to communicate with each other. The apparatuses further drive a pump to collect the application liquid from a liquid applying member and channels to the storage tank. Once the collecting is finished, the air communicating valve is closed.

摘要： For a liquid applying mechanism of an ink jet printing apparatus, a liquid to be used for applying it to a medium is prevented from evaporating and leaking from a liquid holding member. An applying roller and the liquid holding member contact with each other to hold the liquid and apply the held liquid to a printing medium by means of the applying roller. In this configuration, the surface of the applying roller has no irregularities. Thereby, the applying roller can contact with the liquid holding member to form an adequate liquid-tight seal therebetween.

摘要： A liquid application device includes a rotating unit for rotating an application member to apply liquid to a medium in contact with the application member, a liquid application unit including the application member, and a retention member for retaining liquid in a sealed liquid retention space formed to be in contact with the application member. The liquid application unit applies the liquid retained in the liquid retention space to the medium via the application member by rotating the application member. In addition, a control unit controls the rotating unit, wherein the control unit controls, after receiving information of instruction on applying liquid to the medium, the rotating unit to rotate, before the application member contacts the medium, the application member so that the rotating unit performs a preliminary rotation that forms a pool of the liquid in an area. The area is upstream, in a rotational direction, of a contact area between the retention member and the application member at a side where a surface of the application member enters a contact area with the retention member, and the area is downstream, in the rotational direction, of a contact area between the medium and the application member when transferring the medium.

摘要： The present invention provides a liquid application device, an inkjet recording apparatus and a recording apparatus, which are capable of performing an adequate application initial operation according to the length of waiting time and power-off time, as well as a method of controlling the liquid application device. In the present invention, information on an end time of the previous processing for collecting liquid is read from a nonvolatile memory, current time information indicating the current time is obtained, and information on a lapse of time from the end time of the previous collection to a start time of the current application. Thereafter, the number of preliminary rotations R of an application roller is decided based on the information on the lapse of time with reference to a look-up table. Sequentially, the application roller is rotated by the decided number of preliminary rotations R to perform preprocessing operation.

摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, when symmetrically arranged ejection opening rows for a cyan, magenta, and yellow inks are used in the print head, one-pass bidirectional printing is executed. On the other hand, if ejection opening rows for a black ink are used in addition to the above ejection opening rows, multi-pass printing is executed so that there are a number of dots formed with one application order for the black and other color inks and the same number of dots formed with another application order for the black and other color inks. This reduces the non-uniformity of the colors attributed to the difference in application order.
