Abstract:
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.
