Abstract
A liquid discharger includes a head including nozzles to discharge liquid from the nozzles, a detachable first container attached to the liquid discharger to accommodate the liquid, a second container connected to the head to accommodate the liquid to be supplied to the head, a supply channel to connect the first container and the second container, an irreversible pump connected to the second container, and a controller to control the irreversible pump to pressurize and decompress the second container to reciprocally move the liquid between the first detachable container and the second container via the supply channel.
Claims15
A liquid discharger comprising:
- a head including nozzles, to discharge liquid from the nozzles;
- a detachable first container attached to the liquid discharger to accommodate the liquid;
- a second container connected to the head to accommodate the liquid to be supplied to the head;
- a supply channel to connect the first container and the second container;
- an irreversible pump connected to the second container;
- and
- a controller to control the irreversible pump to pressurize and decompress the second container to reciprocally move the liquid between the first container and the second container via the supply channel.
A liquid discharger comprising:
- a head including nozzles to discharge liquid from the nozzles;
- a container connected to the head to accommodate the liquid to be supplied to the head;
- an irreversible pump connected to the container;
- a first three-way valve connected to a first end of the irreversible pump and the container;
- a second three-way valve connected to a second end of the irreversible pump and the container;
- and
- a controller to control the irreversible pump, the first three-way valve, and the second three-way valve to alternately pressurize and decompress the container.
A liquid stirring method for a liquid discharge device including a first container, a second container connected to the first container, and an irreversible pump connected to the second container,
- the method comprising pressurizing and decompressing the second container with the irreversible pump to reciprocally move liquid between the first container and the second container.
