摘要： Changes in toner developability of toners in a liquid toner system are determined and compensated for by sensing the toner concentration and liquid toner volume in a tank, based on changes in the toner concentration and toner mass in the tank. Based on the foreground areas for a color separation layer corresponding to a particular toner, the developed area for that toner for one or more printed pages can be determined. From the developed area and the consumed mass of toner, a developed mass per unit area (DMA) can be determined. Based on the determined DMA, the sensed toner concentration and a voltage differential, the developability of the toner can be determined. Based on a target DMA, the sensed toner concentration and the determined developability of the toner, a new voltage differential can be determined. If the new voltage differential is within a determined range, a target toner concentration is updated based on the target DMA, the determined developability and a target voltage differential for that toner. Based on the updated target toner concentration, toner and/or liquid carrier material can be added to the tank for that toner to change the sensed toner concentration to the updated target toner concentration. In multi-component toners, this method is used to determine the developability of each component. Based on the developability and target DMA of each component of a multi-component toner, new target concentrations of each toner component are determined. Accordingly, the developability of single- and multi-component toner can be corrected for.
