ABSTRACT:
A charge electrode array for a multi-nozzle ink jet array is fabricated from alternate layers of stainless steel and epoxy resin. The charge electrode array may be formed by positioning stainless steel tabs in previously grooved nonconductive substrate such as ceramic. The grooves are spaced sufficiently apart to allow insulating material to be placed between each stainless steel tab. Alternatively, a stainless steel plate may be bonded to a nonconductive substrate. Then the stainless steel can be sliced so that insulating material can be placed between each stainless steel strip. Epoxy fills the gap between tabs or strips forming an insulating layer. An ink drop charging channel through each tab or strip is formed by drilling through the tips of the steel tabs or strips, or by cutting U-shaped channels through the tips of the tabs or strips.
