    摘要： The present invention generally relates to an imaging system, and more specifically, a method and apparatus for accurately predicting toner usage and hence toner dispensing requirements in an imaging system. More particularly, the present invention relates to a toner concentration control system for maintaining toner concentration in a developer structure, which is connected to a dispenser containing toner. The toner concentration control system comprises: a sensor, reading the toner concentration; means for determining a toner age correction of toner concentration read by the sensor based on toner age of the toner in the developer structure; means for adjusting a toner concentration target based on the correction; and means for generating a feedback dispense command based on the adjusted toner concentration target to dispense toner into the developer structure to maintain the toner concentration in the developer structure.

    摘要： A color marking system includes a control system for maintaining an accurate representation for approximating color space transformation comprising a set of piecewise homeomorphisms. The homeomorphisms and parametric models are selectively adjustable in accordance with printer/display calibrating data. Preferably the homeomorphisms comprise corresponding tetrahedra with domain and co-domain color spaces. If error above a selected level is detected, the tetrahedra are adjusted by calculating new locations for their vertices having a consequence of recomputation of model parameters and converging parametric model performance in accordance with a predetermined objective of the system. An inverse of the model is used for feedforward control of the marking system.
