An array of liquid dispensing elements are positioned on a substrate. Each liquid dispensing element includes a liquid dispensing channel positioned on the substrate. The liquid dispensing channel includes an outlet opening positioned on a wall opposite the substrate. A diverter member is associated with the liquid dispensing channel. A liquid return channel is positioned on the substrate and is in fluid communication with the liquid dispensing channel. A liquid supply channel is positioned on the substrate and is in fluid communication with the liquid dispensing channel. A liquid supply passage extends through the substrate and is in fluid communication with the liquid supply channel. A liquid return passage extends through the substrate and is in fluid communication with the liquid return channel. A liquid is provided that flows from the liquid supply passage through the liquid supply channel, through the liquid dispensing channel, through the liquid return channel to the liquid return passage of the array of liquid dispensing elements. A liquid drop is ejected from the outlet opening of the liquid dispensing channel of one of the liquid dispensing elements by selectively actuating the diverter member of the liquid dispensing element to divert a portion of the flowing liquid through the outlet opening of the liquid dispensing channel of the liquid dispensing element.
