Abstract
A method of manufacturing an inkjet printer component and an inkjet printer component electropolishing device are provided. The method includes positioning an electrode in a fluid passageway of an inkjet printer component, the electrode including a conductive face and a nonconductive face; polishing a side of the fluid passageway by: biasing the nonconductive face of the electrode toward a side of the fluid passageway such that the conductive face of the electrode does not contact any portion of the fluid passageway; providing an electrolytic fluid to the fluid passageway of the inkjet printer component; and applying a voltage between the electrode and the inkjet printer component.
