ABSTRACT:
An inkjet printhead assembly includes an elongate casing that defines a longitudinally extending printhead module channel. A printhead module is positioned in the channel and has a fluid channel member that defines a number of longitudinally extending channels. A plurality of printhead tiles is mounted on the fluid channel member. Each printhead tile is in fluid communication with the channels via outlet ports in fluid communication with said respective channels. A printhead integrated circuit is mounted on each printhead tile. The tiles are configured to nest with each other and the printhead integrated circuits are oriented to have adjacent overlapping end portions. Power and control circuitry is mounted on the casing. Flexible printed circuit boards interconnect the printhead integrated circuits and the power and control circuitry.
