Abstract
A fluid ejection device includes a body defining an interior bore, a fluid reservoir, and a fluid ejection chip. The fluid reservoir defines an interior passage that receives a fluid, the interior passage in fluid communication with the interior bore of the body. The fluid ejection chip is coupled with the body and includes one or more fluid ejection actuators. The fluid ejection chip has one or more interior fluid paths in fluid communication with the interior bore of the body so that the fluid ejection chip ejects the fluid upon activation of the one or more fluid ejection actuators. The interior passage of the fluid reservoir and the one or more interior fluid paths are substantially devoid of obstructions such that the fluid is gravity fed to the fluid ejection chip upon entry into the interior passage of the fluid reservoir.
