To print a character on the product, individual drops of ink are electronically controlled to the correct positions.
Ink is pressured by the Ink Supply Pump and flows from the Main Ink Bottle to the Nozzle parts.
The Nozzle uses ultrasonic vibration to separate a solid pressurized ink stream into small ink droplets as it exits the Nozzle orifice.
The droplets ejected from the Nozzle orifice pass through the Charge Electrode tunnel, and then between the Deflection Electrodes.
Each droplet passing through the Charge Electrode receives a Deflection Voltage charge where Deflection Voltage varies between droplets. These charged droplets deflect in a predetermined array pattern depending on the Deflection Voltage charge.
After the droplets pass through the Deflection Electrodes, they continue to travel in their predetermined array pattern out of the Printhead and onto the substrate.
Droplets that aren't required for printing are retrieved by the Gutter and recycled back into the Main Ink Bottle for reuse.
