摘要： In an ink-jet apparatus employing an ink-jet head having a plurality of heaters corresponding to one ink ejection opening, appropriate preliminary ejection is performed per each ejection amount mode set by a heater to be used among a plurality of heaters. Depending upon a set printing mode, printing is performed in one of large, medium and small ejection amount modes. For example, after printing is performed for a predetermined amount by the small ejection amount mode, preliminary ejection during printing is performed in the medium ejection amount mode, which is greater in ejection amount than the small ejection amount mode. By this, the interval between preliminary ejections during printing can be set to be longer to prevent lowering of throughput due to the preliminary ejection operations.

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： An ink jet recording apparatus is provided that changes the adjustment temperature of a recording head depending on the number of recording media so that a favorable recording result can be maintained for any number of recording media and a time required for the recording can be reduced. Different adjustment temperatures T2 are used depending on the number of recording media. When the number of recording media is relatively small, T2 is determined to be low and, when the number of recording media is relatively large, then T2 is determined to be high. When the recording is started, when the head temperature is lower than the determined temperature T2, then ink is heated by a sub heater. Depending on the determined temperature, an interval with which a preliminary ejection is performed is changed.
