Abstract
A method of obtaining a correction value of an optical sensor detecting an edge of the medium so as to generate detection information, includes: acquiring edge information on an edge position of one of opposite edges of the medium based on the detection information; forming on the medium a correction value obtainment pattern including lines that are arranged at a fixed interval in a first direction and parallel to a second direction perpendicular to the first direction and that include a reference line spaced a first distance from the edge position in the first direction and parallel to the second direction, based on the edge information; specifying a line spaced the first distance from the edge position in the first direction; obtaining a second distance in the first direction between the specified line and the reference line; and determining the second distance as an absolute value of the correction value.
