Abstract: A thermal bubble inkjet print head chip has a substrate (11), a heating resistor (12) formed at a first side of the substrate, and an ink accommodating cavity (13) formed at one side of the heating resistor distant from the substrate. A low heat conduction cavity (14) is formed in the substrate; the low heat conduction cavity is located at one side of the heating resistor distant from the ink accommodating cavity; the low heat conduction cavity is filled with a material having a heat conduction efficiency lower than the substrate. By means of the low heat conduction cavity, the amount of heat generated by the heating resistor and diffusing to the substrate is reduced, and the heating efficiency of the heating resistor is improved; therefore, the working current of the heating resistor can be correspondingly lowered.

Fluid wells reside in the flow feature layer under a cover and connect to the channel whereby fluid can dwell for diagnostic applications.

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.
