ABSTRACT:
A drop selection assemblage for use in a printhead and method of making includes a drop generator with a jet array for releasing a drop stream along a normal drop path. The drop stream includes print media drops and recycle drops. The assemblage has a charge structure disposed in a spaced apart relationship to the jet array. The charge structure is a substrate with a non-beveled and beveled portion sloped between 3 degrees and 25 degrees relative to the normal drop path. The charge structure has one or more drop charging electrodes on the non-beveled portion to charge recycle drops and one or more short detection electrodes on the beveled portion. A catcher is located adjacent to the charge structure for catching drops that have passed along the charge structure. The print media drops are selected, and the recycle drops are deflected without either contacting the charge structure.
