摘要： For a liquid applying mechanism of an ink jet printing apparatus, a liquid to be used for application 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 way of the applying roller. In this configuration, the surface of the applying roller has no irregularities. Thereby, the applying roller can contact the liquid holding member to form an adequate liquid-tight seal 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： 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： A liquid applying apparatus can prevent an applying liquid from evaporating while an applying operation is stopped and can reliably prevent the liquid from leaking even when, for example, the posture of the apparatus is tilted. An abutting member of a holding member is abutted, under an urging force of a spring, against an applying surface of an applying roller. Thus, a liquid holding space is formed between the applying roller and a holding member to hold the applying liquid. The abutting member is annularly formed of a single member. The applying roller rotates to cause the applying liquid held in the holding space to adhere to an outer peripheral surface of the applying roller. The applying liquid is then applied to the applying medium.

摘要： In an ink jet printing apparatus using many types of inks to execute bidirectional printing, if ejection opening rows for yellow, magenta, and cyan inks are symmetrically arranged, ejection opening rows for a black ink are arranged adjacent to the most inside ejection opening rows for the yellow ink. Thus, a difference in color between forward scanning and backward scanning is determined by a difference in coloring between the black ink and the yellow ink. In this case, a possible color drift attributed to bidirectional printing can be suppressed by selecting the inks so that the difference in coloring between the black ink and the yellow ink is smaller than that between the black ink and the other color inks.
