US Patent 7537317 Printhead assembly with end-to-end printhead integrated circuit carriers

A printhead assembly includes an elongate support structure. A series of side wall sections extend a length of the support structure and define ink supply channels. Edges of the walls delineate a gap. A plurality of carriers is positioned end-to-end in the gap and is supported by said edges of the walls. The carriers define a recess and ink supply passages in fluid communication with the recess and the ink supply channels. A printhead integrated circuit is mounted in each recess to receive ink from the ink supply channels.
