ABSTRACT:
A wet electrographic printer has (1) a reservoir for supplying a developer obtained by mixing a liquid carrier with an ink to a developing unit, (2) a carrier cartridge for supplying the liquid carrier to the reservoir, (3) an ink cartridge for supplying the ink to the reservoir, and (4) a process tank for receiving the processor from the reservoir. The developer supply method includes the steps of supplying the liquid carrier and the ink to the reservoir to fill the reservoir to a maximum level with developer having an optimum concentration, and determining whether the concentration and level of the developer in the reservoir is less than or equal to a minimum concentration and a minimum level, respectively. If the concentration of the developer is less than or equal to the minimum concentration and the level is higher than the minimum level, the developer is drained from the reservoir to the process tank until the level of the developer falls to the minimum level. Subsequently, liquid carrier and ink are supplied to the reservoir to fill the reservoir to the maximum level with developer having the optimum concentration. If, on the other hand, the concentration of the developer is higher than the minimum concentration and the level of the developer is less than or equal to the minimum level, liquid carrier and ink are supplied to the reservoir to fill the reservoir to the maximum level with developer having the optimum concentration.
