The invention provides an ink-jet printer for enabling precise and automatic detection of an ink jetting failure in an ink-jet head. When ink in an ink tank decreases up to an ink supplement level, a fixed quantity of ink in the shape of a pellet is supplied the number of jetted ink droplets corresponding to print data and the like, are counted, and the printing operation is executed. When ink again decreases up to quantity for ink to be supplemented, the calculated ink consumed quantity calculated based upon the counted number of jetted ink droplets and the quantity of ink in the ink pellets, are compared. If both are not equal, it is determined that an ink jetting failure has occurred. Then, after a maintenance operation is executed, ink is again supplied and the printing operation is continued.
