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： In-image preliminary ejection is performed by use of nozzles used to print an image out of the nozzles included in an overlapping link region, and between-image preliminary ejection is performed by use of nozzles which are not used to print the image. Thus, a reduction in image quality is inhibited, while the amount of print media used in the between-image preliminary ejection is reduced.

摘要： The invention provides a printing apparatus and a recovery method therefore which can minimize ink consumption in a recovery process for a print head of the apparatus. The invention has a control unit to cause a print head to eject ink from nozzles arrayed on the print head so as to recover ink ejecting function of the nozzles, and a specification unit to specify a set print mode selected from among a plurality of print modes. The print modes define number and position of nozzles in use for printing an image. The control unit executes a first preliminary ejection process before or after printing an image on a print medium. The first preliminary ejection process has selectively ejecting ink from both of the nozzles in use selected by the currently set print mode and the unused nozzles in the vicinity of the nozzles in use.

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.

摘要： An inkjet printing apparatus and a print head recovery method are provided according to which, in an environment in which dust (e.g., paper dust) is easily attached to the periphery of an ejection port of a print head, the print head is subjected to a recovery operation depending on the level of the attached dust. The inkjet printing apparatus has a cutter unit for cutting a print medium and a recovery unit for performing the recovery operation by wiping the ejection port formation portion at which the ejection port is formed of the print head while sucking the ejection port formation portion. When the passing number showing how many times the cut part of the print medium cut by the cutter passes the printing position is equal to or higher than a threshold value, the recovery means subjects the print head to the recovery operation.

摘要： A process of detecting a defective recording element and a process of correcting the defective recording element are performed with appropriate processing loads. When the detection process and the correction processes are performed with small loads, for example, at a time of recording, a resolution used for reading an inspection pattern is set lower than that set in a case where the processes can be performed with small loads, for example, at down time before recording. The reading resolution to be set may be determined by an apparatus in accordance with a processing load or may be arbitrarily determined by a user.

摘要： First humidified gas is supplied from a first supply port to a sheet to be conveyed, thereby increasing the moisture content of the sheet. Simultaneously, second humidified gas is supplied to a space where nozzles of the inkjet recording head are exposed, from a second supply port provided at a position closer to the inkjet recording head than the first supply port, thereby increasing the atmosphere humidity of the space. The part of the sheet of which the moisture content has been increased is made to enter the space where the atmosphere humidity has been increased, and recording is performed by the inkjet recording head.
