  • Method for printing on a print media
    Patent number: 7648216
    Abstract: In a method for printing on a print media using nozzles in a printhead, it is determined as to whether one or more of the nozzles are out. In response to the one or more of the nozzles being out, the print media is micro-linefed between at least two printing passes of the printhead when the printhead is substantially in position to print onto a margin section of the print media. The micro-linefeeding includes activation of a print media feed means to advance the print media for a distance that is substantially smaller than a normal advance of the print media, to thereby reduce printing defects in the margin section caused by one or more nozzles that are out.
