Abstract:
A controller for a fluid ejecting system having a refillable container includes an ejection count initializing circuit, routine or application, a count incrementing circuit, routine or application, at least one fluid level indicator, and a fluid quantity circuit, routine or application for determining an expended quantity of fluid, a fluid reserve capacity circuit, routine or application for determining a fluid reserve capacity in the container, an ejection job determining circuit, routine or application for determining a fluid job requirement, a reserve comparing circuit, routine or application to compare the fluid reserve capacity and the fluid job requirement, and a refill condition determining circuit, routine or application to determine that the container is to be refilled. Counts for a ejection amount and a reserve capacity are incremented in response to a specific amount of fluid being ejected from the container. The expended quantity of fluid is based on the ejection amount count subsequent to the fluid level being indicated.
