Method for hydrophilizing surfaces of a print head assembly

摘要

A method for hydrophilizing surfaces of a printhead assembly includes decontaminating the printhead assembly; plasma activating the surfaces of the printhead assembly; treating the surfaces of the printhead assembly with a treatment solution; drying the printhead assembly; baking the printhead assembly; and performing a print quality and electrical test on the printhead assembly. The step of decontaminating the printhead assembly is performed before the step of plasma activating the surfaces of the printhead assembly.

1. A method for hydrophilizing surfaces of a printhead assembly, the method comprising steps of:
plasma activating the surfaces of the printhead assembly at atmospheric pressure; treating the surfaces of the printhead assembly with a treatment solution; drying the printhead assembly; and baking the printhead assembly,wherein the step of plasma activating includes a first propagation of plasma through ink pathways of the printhead assembly, from a nozzle-side of the printhead assembly through to an ink-supply-side of the printhead assembly and a second propagation of plasma through the ink pathways of the printhead assembly, from the ink-supply-side of the printhead assembly through to the nozzle-side of the printhead assembly.
