Abstract
A liquid discharge apparatus to apply liquid to an application surface includes a head and processing circuitry. The head applies the liquid discharged from a nozzle to the application surface. The processing circuitry outputs abnormal discharge information of the nozzle. The abnormal discharge information is detected based on a shape of the liquid applied to the application surface.
Claims20
A liquid discharge apparatus to apply liquid to an application surface, the liquid discharge apparatus comprising:
- a head configured to apply the liquid discharged from a nozzle to the application surface;
- and
- processing circuitry configured to control the head during relative movement between the head and the application surface to form a linear pattern of the liquid on the application surface extending in a pattern extending direction, and to output abnormal discharge information of the nozzle detected based on a shape of the liquid, as applied to the application surface in the linear pattern, along a line substantially orthogonal to the pattern extending direction.
A liquid discharge method to be executed by a liquid discharge apparatus that applies liquid to an application surface, the method comprising:
- applying the liquid discharged from a nozzle to the application surface by a head;
- controlling, with processing circuitry, the head during relative movement between the head and the application surface to form a linear pattern of the liquid on the application surface extending in a pattern extending direction;
- and
- outputting, with the processing circuitry, abnormal discharge information of the nozzle detected based on a shape of the liquid, as applied to the application surface in the linear pattern, along a line substantially orthogonal to the pattern extending direction.
A non-transitory, computer-readable storage medium storing computer-readable program code that causes a liquid discharge apparatus that applies liquid to an application surface, to perform:
- applying the liquid discharged from a nozzle to the application surface by a head;
- controlling, with processing circuitry, the head during relative movement between the head and the application surface to form a linear pattern of the liquid on the application surface extending in a pattern extending direction;
- and
- outputting, with the processing circuitry, abnormal discharge information of the nozzle detected based on a shape of the liquid, as applied to the application surface in the linear pattern, along a line substantially orthogonal to the pattern extending direction.
