ABSTRACT:
If one page of recording is terminated, a carriage moves to a position at which a recording head is located opposite a cap. Then, the ink is discharged through nozzles of the recording head onto temperature detecting element within the cap. Temperature change of the temperature detecting element upon contact with the ink is output from a detecting circuit, and the normal discharge of ink is detected by discharge detecting means. In this way, a decrease in the ink remaining or the detection of ink nondischarge can be securely made.
