1. A printing apparatus producing method for producing a printing apparatus adjusted from a printing apparatus before adjustment, the printing apparatus producing method comprising:
causing a printing section of the printing apparatus before adjustment to print a multiple circle pattern and an adjustment pattern in predetermined relative positions on a medium, the multiple circle pattern being a pattern indicating a plurality of circumferences of concentric circles having different radii;
setting the printed medium with respect to a scan section;
scanning the printed medium and generating a scan image;
detecting the multiple circle pattern from the scan image;
detecting the adjustment pattern based on the relative positions and a detection position of the multiple circle pattern;
calculating adjustment parameters based on a detection result of the adjustment pattern; and
storing the adjustment parameters in a nonvolatile memory of the printing apparatus before adjustment.
