摘要： There is provided an inkjet printing apparatus which executes a proper recovery operation in accordance with the demounting time period of an ink tank and information of the ink tank. In the inkjet printing apparatus of this invention, the demounting time period and information of the ink tank are used as parameters for determining the condition of a recovery operation after the ink tank is once demounted and thereafter mounted again. Since recovery is done in consideration of the degrees of ink evaporation and an increase in viscosity, wasteful ink consumption can be suppressed while a necessary recovery operation is performed.

摘要： Even if an error occurred in a result of the detection by an optical detecting mechanism for optically detecting whether or not a remaining amount of ink in an ink tank is equal to or less than a predetermined amount, a correct situation of the remaining ink amount in the ink tank can be detected. A detecting method has a first discriminating step of discriminating whether or not a remaining ink amount in the ink tank is equal to or less than a predetermined amount by using an optical sensor and a second discriminating step of discriminating whether or not the remaining ink amount in the ink tank is equal to or less than the predetermined amount on the basis of information regarding an amount of ink consumed in the ink tank. If the absence of ink is determined in either the first or second discriminating step, information showing the absence of ink is notified.

摘要： A smooth, uniform image is produced by minimizing the occurrence of satellites of secondary color and dispersing landing positions of the satellites as uniformly as possible. For this purpose, the printing operation performed so that satellites of the two inks (cyan and magenta ink, foe example) ejected toward the same pixel are separated and landed on opposite sides of the main dots on the same pixel. This makes the distribution of satellites uniform and makes individual satellites less noticeable, maintaining the uniformity of an image.

摘要： In the ink-jet printing apparatus, the influence of displacements of printing positions caused by the excessive conveyance of a printing medium to the resultant image when the rear end of the printing medium exits from a nip portion between the roller pair in a conveying mechanism. More specifically, in the printing operation for the rear end portion of the printing medium in which the printing medium exits from the roller pair, the guide shaft for supporting the carriage is lifted at a position wherein a head-medium distance is changed to widen a distance between the printing had and the printing medium (S402). Thereby, the displacement of the landing position caused by the excessive conveyance of the printing medium is inconspicuous because of the variations of the landing positions due to the widening of the head-medium distance.

摘要： An inkjet printing apparatus and method can efficiently feed printing media stored in a media storage unit, while at the same time minimizing the reduction in a printing speed during the ejection recovery operation. The ejection recovery operation is performed during a period extending from the end of printing for a preceding printing medium which is fed first by a feeding unit, to start of printing for a succeeding printing medium. The recovery operation is controlled at this time in accordance with a feeding condition under which the feeding operation performed by the feeding unit is determined.

摘要： On performing a predetermined printing operation, whether or not, among a plurality of printing elements, only a part of the printing elements are applied is detected. If it is judged that only the part of the printing elements are used, a judgment is made whether or not the preliminary discharge operation is performed based on the number of discharges for the part of the printing elements, and if it is not judged that only the part of the printing elements are used, a judgment is made whether or not the preliminary discharge operation is performed based on the number of discharges for all of the printing elements of the printing head. This eliminates an unnecessary preliminary discharge for non-printing elements even in a printing operation mode in which only a part of the printing elements are applied.

摘要： 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.

摘要： A printing apparatus includes a plurality of inkjet print heads to which humidified air is supplied to retain the humidity in the print heads. Ink colors for the plurality of heads are arranged in a sequence corresponding to ink characteristics. The plurality of print heads are arranged in a sequence such that a print head configured to eject ink characterized by having a larger amount of volatile components evaporated within a predetermined time is located in a more upstream area.
