Abstract

A method and system for the determination of toner usage in proportion to image-feature density, with independent estimation of each color toner module consumption. The system accurately accounts for image-wise color interactions due to color occlusion that may effect the actual amount of toner used by multiple color modules. The method includes a toner replenishment flow control process that responds to the toner consumption/depletion in the developer material (e.g., toner and carrier) as determined by one or more estimation modules, and thus maintains a stable and constant toner/carrier concentration ratio.
