    摘要： Image deterioration due to decrease in transfer amount, which arises when a remaining amount of wetting liquid for wet wiping is decreased, is reduced in an ink-jet printing apparatus. When the remaining amount of the wetting liquid decreases to reach a predetermined amount or less, a wetting liquid tank is moved down, and thereby an intrusion amount of a wiper into a transfer portion is made larger than a standard value. This increases an area of the wiper where the wiper comes into contact with the transfer portion, which allows the transfer amount to be maintained at a substantially same level as the reference value. This enables the transfer amount to be prevented from decreasing when the remaining amount decreases, and the transfer amount almost the same as that in an initial stage to be ensured even in a later stage of an apparatus life time.

    摘要： When the head temperature Tfinish, which is the head temperature at the time of completion of a preceding scan, is higher than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT lower than the head temperature Tfinish. On the other hand, when Tfinish, the head temperature at the time of print completion, is lower than the stable ejection temperature Tstable, the target temperature is made a temperature that is only a temperature value ΔT higher than the head temperature Tfinish. Because of this it is possible to inhibit head temperature rise in the case where an image with a high print density is printed.

    摘要： A content of (an amount of ink to be suctioned for, or the number of times ink is preliminarily ejected for) the maintenance process to be performed after the ink tank replacement is made different depending on the amount of ink so far consumed from a tank which is replaced. This makes it possible to check the color mixture which would otherwise occur after the new ink tank is attached to the printing apparatus, and to concurrently manage an amount of waste ink in order that ink should not be consumed more than necessary in a case where the color mixture is less likely to occur.

    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 ink jet recording apparatus is structured to perform discharges in the capping status when preliminary discharges are performed in a shot number larger than a predetermined number, and perform discharges in a cap or a preparatory port other than the cap when the preliminary discharges are performed in a shot number less than the predetermined number. With the structure thus arranged, it is made possible to implement the suppression of the mist generation due to the preliminary discharges, and to make the time of recording on a recording medium shorter as well.
