    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： 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.

    摘要： In the case of printing a test pattern with an inkjet print apparatus, there are two printing mode are prepared. In one printing mode, a preliminary ejection on the printing medium is performed during printing a test pattern, and in the other print mode, the preliminary ejection on the printing medium is not performed during printing a test pattern. For a test pattern that is, if the test pattern is printed under the same condition as that for an actual image, convenient for a subsequent correction, the preliminary ejection on the printing medium is performed during printing of the test pattern. On the other hand, for a test pattern in which, if an irrelevant dot is printed within the pattern, inconvenience is taken into consideration in a subsequent correction, the preliminary ejection on the printing medium is not performed during printing of the test pattern.

    摘要： An inkjet printing device that performs printing on a print medium with a print head including a nozzle for discharging ink, includes: a transport unit transporting the print medium; a printing unit discharging the ink while transporting the print medium such that the printing unit prints an image for printing and an image formed by a preliminary discharge; a first limiting unit limiting, based on image data on the image for printing, an ink amount to be discharged such that the amount of ink per unit area is equal to or less than an upper limit Alim; and a second limiting unit limiting an ink amount to be discharged for the image formed by the preliminary discharge such that the amount of ink per unit area is more than the upper limit Alim and is equal to or less than an upper limit Blim.

    摘要： A drying apparatus includes: a rotatable belt which has an outer surface and an inner surface, the outer surface contacts a sheet; a blowing mechanism which blows hot air on the sheet at a side of the outer surface; and a heating unit which includes a heating element and a contact surface which is disposed in contact with the inner surface. A plurality of rollers are arranged in a direction in which the sheet travels. The rollers are pressed against the outer surface of the belt with the travelling sheet being held between the rollers and the outer surface of the belt.
