Abstract
A multi-fluid body and an ejection head substrate connected in fluid flow communication with the multi-fluid body for ejecting multiple fluids therefrom. The multi-fluid body includes at least two segregated fluid chambers. Independent fluid supply paths lead from each of the fluid chambers providing fluid to multiple fluid flow paths in the ejection head substrate. The ejection head substrate is attached adjacent an ejection head area of the body. The fluid flow paths in the ejection head substrate have a flow path density of greater than about one flow paths per millimeter.
