Ink jet recording apparatus

Abstract

Activation/deactivation of a pump 50 is executed with a delay of a predetermined time from a forward/reverse switching of rotation of a conveying roller 2, while an activation/deactivation of lock means 20 is executed simultaneous with a forward/reverse switching of rotation of the conveying roller 2, and, at the switching of the driving direction of the conveying roller, a difference in timing is provided in the drive transmission so as not to transmit the driving power to the pump for a time necessary for the activation/deactivation switching of the lock means. By separating the cap from the recording head while retaining a negative pressure in the cap after the ink suction operation, thereby reducing the ink amount remaining on the discharge port face or in the cap after the ink suction operation.
