Abstract:
1. An ink jet printing apparatus that performs printing by ejecting ink from a print head, said apparatus comprising: a first conveying roller configured to convey a print medium; a second conveying roller located downstream of the first conveying roller in a conveying direction of the print medium and configured to convey the print medium; a recovery unit configured to perform a recovery operation of the print head; a motor rotatable in first and second directions and configured to produce a drive force for the first conveying roller, the second conveying roller, and the recovery unit; a drive force transmission unit configured to transmit the drive force of the motor so as to rotate the first conveying roller in a forward direction and rotate the second conveying roller in the forward direction when the motor rotates in the first direction, and rotate the first conveying roller in the forward direction, rotate the second conveying roller in a reverse direction, and perform the recovery operation when the motor rotates in the second direction; a detection unit located between the first conveying roller and the second conveying roller in the conveying direction and configured to detect a leading edge of the print medium; and a control unit configured to stop the motor if the detection unit detects a leading edge of the print medium while the recovery unit is performing the recovery operation when the motor rotates in the second direction.
