ABSTRACT:
An ink replenishment system for supplying a working solution of an ink to an electrographic imaging device. A plurality of removable ink cartridges each have at least a first compartment containing ink concentrate and a second compartment. A fluid handling system couples the first compartment of each ink cartridge to a respective working solution reservoir. A controller controls the flow of ink concentrate from each ink cartridge and liquid carrier from a source of liquid carrier to maintain a working solution concentration of working solution in each of the working solution reservoirs. A return system fluidly couples each of the developer stations to the second compartment of the respective ink cartridges. Alternate embodiments include one compartment and three compartment cartridges, and locating the working solution reservoir in the removable cartridge.
