摘要： A liquid applying apparatus can prevent an applying roller from being degraded while contacting with an application liquid for a long time. Specifically, once an applying operation has been completely executed on an applying medium, the apparatus stands by for 60 seconds while holding the application liquid in a liquid holding member. When an applying instruction is not given during this period, the apparatus performs an application liquid collecting operation of discharging the application liquid from the liquid holding member. Thus, upon determining that no applying operation has been performed for a certain period after one applying operation has finished, the apparatus collects the application liquid from the liquid holding member. This avoids immersing the applying roller in the application liquid for a long time. Therefore, the applying roller is prevented from being degraded by the application liquid.

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.

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 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： A liquid applying apparatus and an ink jet printing apparatus can reduce evaporation that may occur when an application liquid is left in a liquid holding member for a long time. The liquid holding member forms a space between an elastic member and a roller to hold the application liquid. The apparatuses also are capable of preventing the leakage of the liquid from the liquid holding member regardless of a variation in the posture of the apparatus. In collecting the application liquid from the liquid holding member to a storage tank, the apparatuses switch 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 channel to the storage tank. Once the collecting is finished, the air communicating valve is closed.

摘要： An inkjet recording apparatus suppresses defective ejection while reducing a consumed ink amount. In the apparatus, a cap-open period, during which a cap member does not cap ejection ports of a recording head of the apparatus, is measured, and a recovery operation executed by a recovery unit is controlled based on a cumulated cap-open period. With the above arrangement, there can be solved a problem that the ink ejecting state of the recording head is deteriorated depending on a recording operation because a cap-open state, in which the cap member does not cap the ejection ports of the recording head, continues while the inkjet recording apparatus executes the recording operation, thereby the reliability of the inkjet recording apparatus can be improved.

摘要： A present invention reduces the generation of periodic uneven print density in the image in a main scanning direction. The present invention focuses attention on a fact that, when a printing head including a plurality of nozzle arrays for ejecting different inks is used to print an image and when the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively short, the displacement of ink impact positions is smaller when compared to a case where the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively long. Thus, a dot arrangement pattern allocated to the pixel data is selected so that the same pixel is printed by a combination of nozzle arrays in which an interval in the main scanning direction is relatively short.
