In an electrophotographic printer, an apparatus for supplying a liquid toner that has a solids concentration within a predefined range. A concentrated solids material and a carrier liquid is contained within a reservoir. The concentrated solids has a solids concentration higher than the predefined range and has settled out from the carrier liquid. A tube has its orifice submerged in the concentrated solids material A second tube has its orifice submerged in the carrier liquid. To insure that the second tube remains above the concentrated solids material and simultaneously below the upper surface, a float is formed around the tube. Finally, a mixer is connected to the two tubes and mixes the concentrated solids with carrier liquid to create the liquid toner. The solids concentration range is directly related to the rations of the two orifices.
