More Information
Summary:An ink liquid supply system for an ink jet system printer includes a sub tank for introducing a new ink liquid from an ink liquid cartridge and an old ink liquid from a beam gutter included in the ink jet system printer. A float element is disposed in the sub tank, the float element having a specific gravity of, for example, 1.062 which is slightly greater than the specific gravity of a preferred ink liquid suited for the ink jet system printer. In the normal operation mode, the float element is positioned at the bottom of the sub tank. When the ink liquid viscosity increases, the float element moves upward. A detection unit is associated with the float element to develop a control signal when the float element moves upward. In response to the control signal, a dilution is added to the ink liquid contained in the sub tank in order to reduce the viscosity of the ink liquid.
