  • Patent number: 6669320
    Abstract: A serial recording apparatus in accordance with the present invention appropriately selects ink nozzles of an ink head and prints on a sheet so that the amount of printing is substantially equal to an ordinary amount, when an inadequate amount of sheet feed occurs, and then, selects the ink nozzles of the ink head in accordance with how the inadequate amount of sheet feed is so as to carry out the next printing. This avoids that the inadequate sheet feedings are accumulated in the succeeding printings. Accordingly, even when a plurality of inadequate sheet feedings occur during the printings with respect to a single sheet, the inadequate sheet feedings are not accumulated, thereby avoiding that the quality of the printing deteriorates. Thus, it is possible to provide a serial recording apparatus which can resolve the inadequate printing by detecting the amount of sheet feed for each feeding, determining the print area in accordance with each amount of sheet feed, and carrying out the printing.
