Abstract
A micro-fluid ejection head has multiple ejection chips joined adjacently to create a lengthy array across a media to-be-imaged. The chips have fluid firing elements arranged along multiple fluid vias skewed variously to enable seamless stitching of fluid ejections. The firing elements are energized to eject fluid and individual ones are spaced according to colors or fluid types. Overlapping firing elements serve redundancy efforts during imaging for reliable print quality. Variable chips sizes and shapes, including chevrons, are disclosed as are relationships between differently colored fluid vias. Skew angles range variously each with noted advantages. Singulating chips from larger wafers provide still further embodiments as does increased usage of the wafer.
