Patent ID: 7874645

Claim:
A printhead assembly that comprises an elongate casing; a plurality of printhead modules mounted serially on the casing, each printhead module comprising a fluid channel member defining a number of channels extending along a longitudinal axis of the casing; a printhead tile defining a fluid distribution assembly mounted on the fluid channel member in fluid communication with the channels, the fluid distribution assembly being defined by a laminated structure of the printhead tile; a micro-electromechanical printhead integrated circuit mounted on the tile to receive fluid from the fluid distribution assembly, the fluid distribution assembly being configured to supply the integrated circuit with at least ink and to adjust fluid flow to compensate for microscopic nozzles of the printhead integrated circuit; and a securing arrangement on the fluid channel member to secure each module to the casing in a replaceable manner; and drive circuitry arranged in the casing and connected to the printhead integrated circuits to control operation of the printhead integrated circuits.
