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： The present invention provides an ink jet printing apparatus that can substantially prevent possible variation in the color of an image on a print medium discharged from an ink jet printing apparatus. A drying condition is determined under which the color of the image varies until the color of the image becomes a target one having a color difference ΔE of at most 3 from a stable color with substantially no temporal variation. The image is dried according to the drying condition. The print medium is then discharged from the printing apparatus. This enables variation in the color of the image on the print medium discharged from the printing apparatus to be prevented from exceeding 3 in terms of color difference ΔE. As a result, a user can be prevented from perceiving variation in color.

摘要： A recording apparatus has: a recording head having a liquid chamber and nozzles; a tank that stores the liquid which is supplied to the recording head; a liquid supply path that supplies the liquid from the tank to the liquid chamber; a supply pump provided on the liquid supply path; a liquid return path that returns the liquid from the liquid chamber to the tank; a return pump provided on the liquid return path; and a control unit that controls the supply pump and the return pump, wherein when the liquid is initially filled into the liquid chamber, the control unit drives the return pump so as to set the liquid chamber into a negative pressure state and subsequently drives the supply pump. The recording apparatus which can fill the liquid at a high speed without raising a pressure of a flow path can be provided.
