Abstract: In a line-head type inkjet printing apparatus that ejects a plurality of types of inks, an inkjet printing apparatus is provided in which the change of its ejection properties different depending on the type of ink is prevented from occurring. The line-head type printing apparatus includes an acquisition unit that counts the ejection number of liquid from each of print heads in each of a plurality of print heads. Furthermore, the printing apparatus compares the ejection number of liquid from each of the print heads counted by the acquisition unit with a threshold value set for each of the print heads. The printing apparatus includes a change unit that can move a holder in the main scanning direction when the counted ejection number of liquid exceeds the threshold value set for the print head.

Abstract: There is provided an inkjet printing apparatus which can output a stable image without density unevenness by performing appropriate drive control to print elements based upon an appropriate representative temperature of a chip whatever image data is printed on a print medium. For this purpose, detection temperatures of a plurality of temperature sensors are lined up in high temperature order, and coefficients by which the respective detection temperatures are multiplied, are determined to be associated with that order at the lining-up, determining a representative temperature by the weighted average method. The common drive pulse associated with to the individual chip based upon the representative temperature thus obtained, to be applied thereto. Thereby even if temperature variations of print elements on the chip exist, it is possible to appropriately control the entire chip in temperature.

Abstract: A recording apparatus to record an image on a recording medium using a recording head includes a first conveying roller, a second conveying roller, and a controller. The first conveying roller is positioned upstream of the recording head in a conveying direction and the second conveying roller is positioned downstream of the recording head in the conveying direction. In response to a first conveying mode being selected, the controller performs a rotational phase control in which the controller controls rotational phases of the first conveying roller and the second conveying roller such that the recording medium is conveyed by predetermined sections of circumferences of the first conveying roller and the second conveying roller when a trailing end of the recording medium passes the first conveying roller. In response to the second conveying mode being selected, the controller does not perform the rotational phase control.

Abstract: 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.
