摘要： In a method of cleaning an ejection face by supplying a head liquid on a surface (ejection face) of an inkjet head provided with ink ejection outlets, and then by performing wiping operations thereon, an ink residue on the ejection face is efficiently and surely removed from the ejection face to achieve a sufficient cleaning thereon. For this purpose, a first wiping operation is first performed such that a wiper (9A) is relatively largely bent, and slidingly contacts the ejection face at an abdomen thereof to efficiently perform the application, stirring and mixing of the head liquid. Then, a second wiping operation is performed such that an edge portion of the top end of a wiper (9B) slidingly contacts the surface to efficiently scrape the mixture of the head liquid and the ink residue.

摘要： To relate to a head liquid which is supplied to efficiently remove ink residues and the like which are attached to the surface of an inkjet head provided with ejection openings through which an ink containing a color material is ejected. In a case where a nonvolatile solvent such as glycerin is used as the head liquid, the nonvolatile solvent absorbs moisture, and thereby an extremely large change in mass is exhibited. As a result, the above supply amount is varied. To solve the problem, it was found that the previous mixing of water with the nonvolatile solvent can provide a smaller change in mass than that in a case where the nonvolatile solvent by itself is caused to absorb moisture. Accordingly, a mixture prepared by mixing the nonvolatile solvent and water in an appropriate predetermined ratio is used as a head liquid.

摘要： A method of a cleaning of an ejection face by supplying a head liquid on the face of an inkjet head provided with ink ejection openings and then by performing a wiping operation. Sufficient cleaning is achieved by appropriately specifying relative relationships among the surface tensions of the face, the ink and the head liquid, and by efficiently and surely removing an ink residue from the face. By supplying the head liquid to the ink residue on the face, both are mixed with each other, and thereby the ink residue is incorporated into the head liquid. In this respect, by using the ink and the head liquid both having a surface tension higher than that of the face, a wetting of a dissolved matter of the ink residue with respect to the face is reduced, and the dissolved matter of the ink residue is smoothly moved by the wiping operation.

摘要： An ink jet printing apparatus according to the present invention includes a dryer configured to dry ink on a print medium. The dryer includes a heating unit configured to heat air in the dryer, and an outside air adjustment mechanism configured to adjust the amount of outside air introduced into the dryer. When the outside air adjustment mechanism is controlled so that the outside air introduction amount is increased, before the control of the outside air introduction amount, the heating unit is controlled so that heated air heated by the heating unit is preheated to a second target temperature higher than a predetermined first target temperature for a normal operation. Even if the outside air introduction amount is actually increased to temporarily reduce the temperature of heated air, the temperature of the heated air can be maintained at a value required for sufficient drying.

摘要： There is provided an inkjet printing apparatus which are used to obtain a printed matter having a small degree of glossiness unevenness and a flat surface. The apparatus is the inkjet printing apparatus for forming an image on a print medium by relatively scanning a first ejection unit for ejecting a first ink and a second ejection unit for ejecting a second ink to the print medium. The apparatus includes forming unit configured to form the image with the first and second inks on the print medium in each of a first printing mode for completing an image by scanning the first ejection unit one time and a second printing mode for completing an image by scanning the second ejection unit plural times. A gloss value of a solid image with the second ink is greater than a gloss value of a solid image with the first ink.
