ABSTRACT:
The method and equipment for detangling individual jets in an ink jet print station utilizes a reservoir containing fluid and a printhead. The printhead has a drop generator, an orifice structure connected to the drop generator for forming numerous jets, a catcher connected to the drop generator; and a charge device secured to the catcher. A fluid supply system is connected between the printhead and the reservoir. A controller and numerous actuators are connected to the drop generator, and adapted to vibrate the drop generator. A fluid pump is connected to the fluid supply line, is operated by the controller, and is adapted to raise the pressure on the drop generator to at least an operating pressure and lower the pressure on the drop generator to a minimal pressure to prevent entanglement of the jets.
