Abstract
A liquid ejection apparatus includes: a liquid ejector that ejects liquid; a liquid deliverer that delivers liquid to the liquid ejector; and a hardware processor. The liquid deliverer includes a first liquid storage and a second liquid storage that store liquid, and a first liquid channel including a first liquid deliverer that delivers the liquid in the first liquid storage to the second liquid storage. The hardware processor senses an abnormality of the first liquid channel based on a liquid delivery by the first liquid deliverer. The hardware processor is configured to, in a case in which a predetermined condition is satisfied, reduce a liquid level height in the second liquid storage by causing the liquid in the second liquid storage to be discharged.
Claims17
A liquid ejection apparatus comprising:
- a liquid ejector that ejects liquid;
- a liquid deliverer that delivers liquid to the liquid ejector;
- and
- a hardware processor,
- wherein,
- the liquid deliverer includes a first liquid storage and a second liquid storage that store liquid, and a first liquid channel including a first liquid deliverer that delivers the liquid in the first liquid storage to the second liquid storage,
- the hardware processor senses an abnormality of the first liquid channel based on a liquid delivery by the first liquid deliverer, and
- the hardware processor is configured to, in a case in which a predetermined condition is satisfied, reduce a liquid level height in the second liquid storage by causing the liquid in the second liquid storage to be discharged.
A liquid level height control method executed by a liquid ejection apparatus including a liquid ejector that ejects liquid;
- and a liquid deliverer that delivers liquid to the liquid ejector, wherein the liquid deliverer includes a first liquid storage and a second liquid storage that store liquid, and a first liquid channel including a first liquid deliverer that delivers the liquid in the first liquid storage to the second liquid storage, the liquid level height control method comprising:
- sensing an abnormality of the first liquid channel based on a liquid delivery by the first liquid deliverer, and
- in a case in which a predetermined condition is satisfied, adjusting and reducing a liquid level height in the second liquid storage by causing the liquid in the second liquid storage to be discharged.
A non-transitory computer-readable storage medium storing a program that causes a computer of a liquid ejection apparatus including a liquid ejector that ejects liquid;
- and a liquid deliverer that delivers liquid to the liquid ejector, wherein the liquid deliverer includes a first liquid storage and a second liquid storage that store liquid, and a first liquid channel including a first liquid deliverer that delivers the liquid in the first liquid storage to the second liquid storage, the program causing the computer to perform:
- sensing an abnormality of the first liquid channel based on a liquid delivery by the first liquid deliverer, and
- in a case in which a predetermined condition is satisfied, adjusting and reducing a liquid level height in the second liquid storage by causing the liquid in the second liquid storage to be discharged.
