    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: The present invention aims to obtain preferable correction values to correct the conveying error of a conveying roller in accordance with the size of a printing medium, even when the conveying error caused by the eccentricity of the roller varies from a point to another in the longitudinal direction of a roller, depending on the amount and the state of eccentricity of the roller. To achieve this object, correction values are acquired using the whole part of or only a part of plural test patterns formed in the longitudinal direction of the roller. The correction values thus acquired correspond to the respective zones where the test patterns are formed.

    摘要: While a conveying error of a roller depends on the eccentricity of the roller, the amount and the state of the eccentricity sometimes makes the roller have different conveying errors from one point in the longitudinal direction of the roller to another. There is provided a construction for obtaining a correction value that is suitable for the correction of the conveying error even in such a case as described above. To this end, plural test patterns are formed in the longitudinal direction of the roller. Then, a suitable correction value for correcting the conveying error that depends on the eccentricity of the roller is obtained on the basis of these test patterns.
