Ink-jet recording apparatus

An ink-jet type recording apparatus comprising:

• an ink-jet recording head for ejecting ink droplets in correspondence with print data, said recording head having a plurality of nozzle openings;
• means for capping and sealing said recording head and communicating with the atmosphere selectively, and for receiving negative pressure from suction pump;
• a wiping blade for wiping a surface of said nozzle openings of said recording head;
• means for controlling flushing in which the ink droplets are ejected from said recording head to prevent clogging of the nozzle openings of said recording head;
• means for controlling cleaning of said recording head by allowing said suction pump to suck ink from said recording head and for allowing said wiping blade to wipe said recording head;
• and
• timing means for starting timing after completion of cleaning and for measuring a time duration required for at least one of disappearance and reduction of air bubbles occurring in a vicinity of the nozzle openings after cleaning;
• wherein said flushing controlling means executes flushing when the time duration measured by said timing means is up.
