Abstract: While moving an ejecting unit, first patterns and second patterns are formed in a first direction on a medium. Third patterns corresponding to the first patterns are formed while changing a shifted amount by which the third patterns is shifted from the first patterns by a first shift amount in the second direction. Fourth patterns corresponding to the second patterns are formed while changing a shifted amount by which the fourth patterns is shifted from the second patterns by a first shift amount in the second direction. In a rough adjustment pattern, image density of a pair of patterns, which are formed of the first pattern and the corresponding third pattern, changes in the first direction in a first cycle. In a fine adjustment pattern, image density of a pair of patterns, which are formed of the second pattern and the corresponding fourth pattern, changes in a second cycle.

Abstract: In a printer configured to perform two-sided recording, a control unit generates a first correspondence relationship that associates a reference pattern with raster data of a first image in a medium transport direction, and a second correspondence relationship that associates the reference pattern with raster data of a second image in the medium transport direction, and, when the second image is recorded on a second surface, performs determination processing for determining whether the reference pattern detected by a detection unit and the raster data of the second image, which a recording unit records when the reference pattern is detected, match the second correspondence relationship.

Abstract: While moving an ejecting unit, first patterns and second patterns are formed in a first direction on a medium. Third patterns corresponding to the first patterns are formed while changing a shifted amount by which the third patterns is shifted from the first patterns by a first shift amount in the second direction. Fourth patterns corresponding to the second patterns are formed while changing a shifted amount by which the fourth patterns is shifted from the second patterns by a first shift amount in the second direction.

In a fine adjustment pattern, image density of a pair of patterns, which are formed of the second pattern and the corresponding fourth pattern, changes in a second cycle.
