Abstract
In a fluid ejection apparatus, fluid flows from a tank, through a fluid inlet, to a fluid supply passage which extends to nozzles. A driver is configured to apply energy to fluid in the fluid supply passage to eject fluid from the nozzles. A purge unit is configured to purge fluid from the nozzles to execute first purging. A controller is configured to receive, from a user input unit, a refill completion signal indicating that the tank is refilled with fluid, obtain an amount of fluid consumed since receipt of the refill completion signal by counting an amount of fluid discharged from the nozzles, and determine an amount of fluid to be purged by the first purging by subtracting the amount of fluid consumed from a total capacity of the fluid supply passage.
