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