As the value is larger, the density becomes lighter. As the value is smaller, the density
becomes darker.
Enter the adjustment value in a unit of +/- 30 gradually, output the test pattern and make
adjustment while checking the test pattern. If the value is changed dramatically, the image
error (while line) may occur.
5-3) After the adjustment, output a test print and check the image.
When uneven density is seen: Go to 5-4).
When uneven density is not seen: Procedure is ended.
