Zusammenfassung:	PURPOSE: A fluid injection system and an operation method thereof, and a fluid distribution method are provided to promote removal of air bubbles from the fluid injection system, and to distribute heat from the fluid injection system by circulating fluid with the fluid injection system. CONSTITUTION: A fluid injection system(30) of an inkjet print head assembly is composed of drop injection factors(31), and drop injection factors are arranged on a substrate(40) with a fluid or ink supply slot(41). Ink is supplied from the fluid supply slot to the drop injection factor. The drop injection factor has a thin film structure(32) having an injection resistor(34), an orifice(36) and a fluid supply channel(33) communicated with the fluid supply slot of the substrate. The substrate comprises a first side having a first opening, and a second side having second openings. The second openings are communicated with the first opening, and plural drop injection factors are formed on the first side of the substrate. Fluid is circulated via the second openings and the first opening of the substrate.
