CARTUCHO DE TINTA PARA UMA IMPRESSORA JATO DE TINTA, MÉTODO IMPLEMENTADO EM UM SISTEMA DE DISTRIBUIÇÃO DE TINTA PARA UM CARTUCHO DE TINTA E CARTUCHO DE TINTA PARA EJETAR SEPARADAMENTE DUAS TINTAS

摘要

In one embodiment an ink pen for an inkjet printer includes: an ink filter chamber; a pressure regulator chamber downstream from the ink filter chamber along a path of ink flow through the pen; a pressure regulator in the pressure regulator chamber; a filter in the ink filter chamber; an inlet to the ink filter chamber upstream from the filter along the ink flow path; and an outlet from the ink filter chamber to the pressure regulator chamber downstream from the filter along the ink flow path such that ink flowing from the inlet to the outlet passes through the filter. In another embodiment a method implemented in an ink delivery system for an inkjet ink pen includes: chambering ink in the pen; filtering the chambered ink; and then regulating the pressure of filtered ink.
