    摘要: High image quality is maintained even on front and rear ends of a printing medium where deterioration in the image quality is more likely to occur due to reduction in conveyance accuracy of the printing medium. In printing on the front and rear ends, the printing medium being not supported by both conveying means respectively placed upstream and downstream of a printing point in a printing medium conveying direction, a print swath of a printing head and the amount of conveying a printing medium are reduced. Moreover, the reducing print swath and the reducing conveyance amount are designed to be decreased in the cases of selecting a printing medium for high-quality printing as well as a monochrome print mode where image distortion caused by deviation of ink-landing positions is more noticeable due to a small number of colors of ink to be used and low coverage thereof.

    摘要: An object of the present invention is to appropriately dispense treatment fluid to wipers, and to always wipe ejection-orifice formation surfaces in a favorable state regardless of an environmental change and the like. To this end, in the present invention, a treatment-fluid holding portion holds treatment fluid used in a wiping operation of wipers. When the wipers contact the treatment-fluid holding portion, the treatment fluid is transferred to the wipers. In an environment where the treatment fluid is thickened, the wipers with ink dispensed thereto are brought into contact with the treatment-fluid holding portion to supply ink to the treatment-fluid holding portion. Thus, the viscosity of the treatment fluid near a contact portion between the treatment-fluid holding portion and the wipers decreases, and the treatment fluid is sufficiently transferred to the wipers.

    摘要: Printing can be properly performed on a print medium other than print media preset in accordance with print modes of a printer. Specifically, when the print medium other than the print media preset in accordance with the print modes is used, patches are printed on the print medium in each combination of the ink ejection amount and the number of passes, and information regarding each evaluation of granularity and banding based on colorimetry of the patches is obtained for each combination of the ink ejection amount and the number of passes. Next, a combination of the maximum ink ejection amount and the maximum number of passes is selected from the combinations that each evaluation of the granularity and the banding satisfies a certain level. Then, a print mode having a combination nearest the combination is selected from the plurality of print modes.
