Abstract
A recording apparatus performs recording with an ink jet recording head that is capable of ejecting ink onto a recording medium. The recording apparatus includes an ink receiving section disposed at a position to be able to oppose an orifice-formed face of the recording head, a preliminary ejection unit for causing ink ejection from discharging orifices toward said ink receiving section by driving said recording head to remove causes of defective ink ejection, an absorption unit for absorbing ink remaining in the ink receiving section as a result of ink ejection by the preliminary ejection unit, and a dry absorption control unit. The dry absorption control unit causes ink absorption by driving the absorption unit when a number of preliminary ejection caused by the preliminary ejection unit, from the time of an absorption previously executed by the dry absorption unit during recording, exceeds a predetermined number.
