Abstract

A first reference portion includes a lower surface of a first color. A second reference portion is adjacent to the first reference portion in a first direction, and includes a lower surface of a second color. An end reference portion is arranged in an end portion of a movable region for a scanning unit to be adjacent to the first reference portion in a second direction. The end reference portion includes a lower surface that includes surfaces of a plurality of specific colors that are aligned in a primary scanning direction. One of the plurality of specific colors is a third color. A data processing section performs a color determination process to determine a color for reference pixel data being included in line image data and corresponding to a reference region. A unit driving apparatus performs drive operations to position the scanning unit at a home position, where the drive operations performed by the unit driving apparatus are successively selected from a plurality of trial drive operations according to a determination result obtained by the color determination process, and the scanning unit is moved a different distance or in a different direction in each of the plurality of trial drive operations.
