Abstract
A liquid dispensing element array is positioned on a substrate. Each liquid dispensing element includes a liquid dispensing channel positioned on the substrate and an associated diverter member. An outlet opening is positioned on a wall opposite the substrate. Liquid supply and return channels are positioned on the substrate in fluid communication with the liquid dispensing channel. Liquid supply and return passages extend through the substrate in fluid communication with the liquid supply and return channels, respectively. Liquid flows from the supply passage through the supply channel, through the dispensing channel, through the return channel to the return passage in the array of liquid dispensing elements. A liquid drop is ejected through 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.
