Modular printhead assembly with serially mounted printhead modules

摘要

A printhead assembly has an elongate casing. A plurality of printhead modules is mounted serially on the casing. Each printhead module has a fluid channel member defining a number of channels extending along a longitudinal axis of the casing. A printhead tile defines a fluid distribution assembly mounted on the fluid channel member in fluid communication with the channels. The fluid distribution assembly is defined by a laminated structure of the printhead tile. A micro-electromechanical printhead integrated circuit is mounted on the tile to receive fluid from the fluid distribution assembly. The fluid distribution assembly is 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. A securing arrangement is on the fluid channel member to secure each module to the casing in a replaceable manner and drive circuitry is arranged in the casing and connected to the printhead integrated circuits to control operation of the printhead integrated circuits.
