ABSTRACT:
An image recording apparatus includes a recording head which includes nozzles, a paper feeding mechanism which feeds a recording medium to the recording head, a paper discharge mechanism which discharges the recording medium from the recording head, a detecting mechanism which detects a change occurred in the paper feeding mechanism or the paper discharge mechanism, a recovery mechanism which recovers a jetting state of the nozzles, a timer which measures a time elapsed after the recovery operation is carried out, and a controller which controls the recovery mechanism according to the elapsed time. When the recovery operation for the nozzles is necessary, an operation preceding the recording operation is detected, and the recovery operation is carried out promptly before the recording operation, thereby shortening a waiting time of a user.
