A liquid dispenser includes liquid supply, dispensing, and return channels. A portion of a first wall of the liquid dispensing channel defines an outlet opening. A second wall of the liquid dispensing channel, opposite the first wall, extends along portions of the liquid supply and return channels. A liquid supply passage, in communication with the supply channel, extends through the second wall. A liquid return passage, in communication with the return channel, is positioned through the second wall and overlaps the outlet opening of the liquid dispensing channel as viewed from a direction perpendicular to a surface of the first wall of the liquid dispensing channel. A liquid supply provides liquid that flows from the supply passage through the supply, dispensing, and return channels to the return passage. A diverter member selectively diverts a portion of the flowing liquid through the outlet opening of the liquid dispensing channel.
