Abstract
A method of cleaning a liquid discharging apparatus has a second flow path cleaning step of causing a cleaning liquid to pass through a second flow path so that the second flow path is cleaned, and also includes a first flow path cleaning step of causing the cleaning liquid that has passed through the second flow path to pass through a first flow path so that the first flow path is cleaned.
Claims4
A method of cleaning a liquid discharging apparatus, wherein
- the liquid discharging apparatus has
- a liquid tank that stores a liquid,
- a discharging head having a nozzle from which the liquid is discharged,
- a supply flow path through which the liquid in the liquid tank is supplied to the discharging head, and
- a valve disposed in the supply flow path, and
- when, with respect to a direction in which the liquid flows toward the discharging head, a flow path for the liquid, the flow path being disposed upstream of the valve, is taken as a first flow path and a flow path for the liquid, the flow path being disposed downstream of the valve, is taken as a second flow path, the second flow path has a smaller volume than the first flow path,
- the method comprising:
- a second flow path cleaning step of causing a cleaning liquid to pass through the second flow path so that the second flow path is cleaned;
- and
- a first flow path cleaning step of causing the cleaning liquid that has passed through the second flow path to pass through the first flow path so that the first flow path is cleaned.

- the liquid discharging apparatus has
- a liquid tank that stores a liquid,
- a discharging head having a nozzle from which the liquid supplied from the liquid tank is discharged,
- a supply flow path through which the liquid in the liquid tank is supplied to the discharging head, and
- a valve disposed in the supply flow path,
- when, with respect to a direction in which the liquid flows toward the discharging head, a flow path for the liquid, the flow path being disposed upstream of the valve, is taken as a first flow path and a flow path for the liquid, the flow path being disposed downstream of the valve, is taken as a second flow path, the method comprising
- a first flow path cleaning step of causing a cleaning liquid to pass through the first flow path so that the first flow path is cleaned, and
- a second flow path cleaning step of causing the cleaning liquid to pass through the second flow path so that the second flow path is cleaned, and
- there is at least a partial overlap between a period during which the first flow path cleaning step is executed and a period during which the second flow path cleaning step is executed.
