    Abstract: Circuits are described involving a method of detecting charges on drops in an ink jet stream without contacting the stream. This permits a determination of proper synchronization and charging of the drops, the velocity of the ink stream, the extent of deflection of the drops, and whether or not the stream is in operation, or has stopped.
