ABSTRACT:
An ink-jet recording apparatus periodically performs the purge process and the wiping process. When the instruction is made to start the recording operation, a control unit judges whether or not the purge process and the wiping process have been performed after the previous recording operation. If it is judged that the purge process and the wiping process have been performed, the recording operation is started after executing the flashing process. Bubbles generated by the purge process are decreased by being dissolved in the ink during the period until the recording operation is started. Therefore, it is possible to avoid any occurrence of the discharge failure which would be otherwise caused by the bubbles contained in the ink. The purge process and the wiping process are separated from the flashing. Therefore, the period of time required for the processes is scarcely inhibits the demand of the user to start the printing.
