Pagewidth printhead with flexible ink delivery extrusion

摘要

A flexible ink delivery extrusion feeds ink and air to a series of printhead modules in an ink jet printhead assembly. A repeating pattern of holes is laser ablated into the extrusion. These interface with inlets on each of the printhead modules of the assembly and relay ink and air from respective longitudinal channels of the extrusion. A rigid support beam determines the overall configuration of the series of modules. The extrusion is flexible enough to accommodate the configuration set by the support beam while not compromising the ink and air flow to the nozzles on each module.
