Printhead parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Gun Body 1× Stainless steel printhead chassis that mounts the jet components and carries the slide-on cover.
2 Drop Generator 3 parts 1× Resonant chamber whose piezo element modulates the ink jet so it breaks into uniform drops.
3 Nozzle 1× 60–70 µm orifice
4 Charge Electrode 1× Slotted electrode that applies a switched 0–300 V charge to each drop at the break-off point.
5 Deflection Plates 1× Plate pair holding a constant ~6 kV field that deflects charged drops proportionally to their charge.
6 Gutter 1× Unprinted drop return
7 Phase Detector 1× Sensing electrode that confirms drops are charging at the correct point in the modulation cycle.
8 Printhead Heater 1× Resistive heater that holds the head at jetting temperature in cold environments.
