According to an embodiment of the present invention, a deflection electrode assembly is provided for use in a continuous ink jet printer of the type which projects a stream of ink drops toward a substrate and controls placement of the ink drops on the substrate by selectively charging the individual ink drops and passing the charged ink drops through a deflection field created by the deflection electrode assembly. The deflection electrode assembly includes a high voltage electrode, a low voltage electrode, and an insulating housing which positions the high and low voltage electrodes in a predetermined spaced relationship along the ink drop stream. The insulating housing also has an internal resistor in electrical connection to the high voltage electrode and an external circuit. The insulating housing also contains an insulating member which supports the high voltage electrode as well as minimizes the possibility for arcing between the two electrodes.
