Abstract
A charge plate and a method for fabricating a charge plate for an ink jet printhead includes the steps of removing portions of conductive material from a dimensionally stable substrate with a coating of conductive material to form at least a first and second electrode on a first face with a first space between the first and second electrodes, removing portions of conductive material from the dimensionally stable substrate with a coating of conductive material to form a first electrode extension which engages the first electrode on the conductive charging face, and a second electrode extension which engages the second electrode on the conductive charging face, whereby the first and second electrode extensions are electrically isolated from each other, additionally forming a first space between the electrode extensions, which connects with the first space between the electrode extensions.
