摘要:
An ink jet recording apparatus records by discharging ink from plural recording heads toward a recording medium. Each of the recording heads has a heat pipe mounted thereon, and protruding therefrom so as to have a length which is greater than the recording width of the corresponding recording head. The protruding portions of each heat pipe extending from the recording heads have a heat discharging member attached thereto. That member constitutes a single blower fan for applying an air stream to the heat discharging members corresponding to the recording head, and plural air stream control means for applying the air stream produced by the blower fan to the heat discharging members individually or independently.
摘要:
A recording head has a plurality of arranged recording elements, wherein the recording elements are selectively supplied with driving signals and driven by electrical energy. The head includes a dividing unit for dividing a plurality of arranged recording elements into at least two blocks each simultaneously operable, and correcting unit for correcting the characteristics of the recording elements in accordance with electrical energy at respective blocks, whereby the recording head's life is prolonged and a high quality picture image can be obtained.
