Abstract
A fluid cartridge has a bottle to retain a volume of fluid. An ejector chip resides in fluid communication with the bottle and causes ejection of fluid upon activation of fluid ejectors. Control logic coordinates ejector activation with dose control logic and temperature control circuitry. The dose control logic pre-specifies an amount of fluid to be ejected and prevents further ejection upon reaching the amount. Meanwhile, the temperature control circuit inhibits any ejection until a temperature of the fluid is within a predefined acceptable range. Bottle modularity, fluid dispense-areas and group-control of the ejectors facilitate certain designs.
