摘要： An optical sensor that outputs a signal based on reflected light intensity is moved in a second direction orthogonal to a transport direction of a medium. A pattern containing patches representing a plurality of gradation levels between a first gradation level and a second gradation level denser than the first is formed such that each patch is located at a different position in the second direction. Signals of the patch of the second gradation level and another patch are outputted. Then signals are outputted with respect to positions in the second direction in a blank region onto which ink has not been dispensed, one of the positions being located at the same position as the patch of the second gradation level, the other position being located at the another patch, so as to correct a dispensing amount corresponding to the gradation level of the another patch.

摘要： A printer includes an ejecting head, and a printing control section, in which the ejecting head ejects ink onto the sheet while performing scanning of a plurality of times with respect to a predetermined raster line which extends in the scanning direction. In addition, the printing control section sets a nozzle use rate of a first complementing nozzle which is higher than a nozzle use rate in normal operation as a nozzle use rate of a complementing nozzle which ejects ink to a pixel to which a defective nozzle should eject ink on the sheet, instead of the defective nozzle, when the defective nozzle is detected, and sets a nozzle use rate of a second complementing nozzle which is lower than that of the first complementing nozzle as a nozzle use rate of a supplementary complementing nozzle which is the peripheral nozzle of the complementing nozzle.
