Abstract
A liquid discharge apparatus includes a plurality of liquid dischargers and circuitry. The plurality of liquid dischargers is configured to discharge liquids of a plurality of colors from discharge holes to form an inspection image on a recording medium. The circuitry is configured to detect a failure of the discharge holes, based on the inspection image formed on the recording medium with the liquids of the plurality of colors. The inspection image includes linear images of the plurality of colors extending in a first direction and arrayed in a second direction intersecting the first direction. Linear images of at least two colors, of the linear images of the plurality of colors, are positioned to overlap each other in the first direction.

A liquid discharge apparatus comprising:
- a plurality of liquid dischargers configured to discharge liquids of a plurality of colors from discharge holes to form an inspection image on a recording medium;
- and
- circuitry configured to detect a failure of the discharge holes, based on the inspection image formed on the recording medium with the liquids of the plurality of colors,
- the inspection image including linear images of the plurality of colors extending in a first direction and arrayed in a second direction intersecting the first direction,
- linear images of at least two colors, of the linear images of the plurality of colors, being positioned to overlap each other in the first direction, and
- wherein a linear image of a first color is arranged at substantially the same position as a linear image of a second color in the first direction;
- the second color differing from the first color.
An inspection method comprising:
- discharging liquids of a plurality of colors from discharge holes of a plurality of liquid dischargers to form an inspection image on a recording medium;
- and
- detecting a failure of the discharge holes, based on the inspection image formed on the recording medium with the liquids of the plurality of colors,
- the inspection image including linear images of the plurality of colors extending in a first direction and arrayed in a second direction intersecting the first direction,
- linear images of at least two colors, of the linear images of the plurality of colors, being positioned to overlap each other in the first direction, and
- wherein a linear image of a first color is arranged at substantially the same position as a linear image of a second color in the first direction;
- the second color differing from the first color.
A non-transitory, computer-readable storage medium storing computer-readable program code that causes a computer to perform an inspection method, the method comprising:
- discharging liquids of a plurality of colors from discharge holes of a plurality of liquid dischargers to form an inspection image on a recording medium;
- and
- detecting a failure of the discharge holes, based on the inspection image formed on the recording medium with the liquids of the plurality of colors,
- the inspection image including linear images of the plurality of colors extending in a first direction and arrayed in a second direction intersecting the first direction,
- linear images of at least two colors, of the linear images of the plurality of colors, being positioned to overlap each other in the first direction, and
- wherein a linear image of a first color is arranged at substantially the same position as a linear image of a second color in the first direction;
- the second color differing from the first color.
