Modular printhead assembly with carrier for maintaining data and power connections

摘要

A printhead assembly for an inkjet printer includes an elongate carrier. A number of printhead modules are mounted on the carrier. Each printhead module includes an ink delivery assembly and a printhead chip mounted on the ink delivery assembly. Flexible printed circuit board assemblies are attached to the carrier and to respective printhead modules for carrying data and power to said modules. A pair of busbars is electrically connected to the flexible printed circuit board assemblies for carrying power to the flexible printed circuit board assemblies. The carrier has a bearing surface and a biasing structure for individually urging the printhead modules against the bearing surface and maintaining the electrical connection between the flexible printed circuit board assemblies an the pair of busbars
