摘要： A method for sensing toner concentration in a developer housing with an optical system containing developer material including toner and carrier, the method, including: emitting light with the optical system through a viewing window in the developer housing onto developer material in the housing; sensing the light reflected off the developer material with the optical system; calculating a toner concentration measurement based upon the sensed light reflected off the developer material; and compensating the toner concentration measurement to account for optical variation due to the developer material condition.

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.

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 specifically, 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 includes a toner mass estimator providing a toner mass estimate of the toner mass in the developer structure to be applied to the photoreceptor; a feed forward dispense unit receiving the toner mass estimate and transmitting a feed forward dispense command based on the toner mass estimate; a toner concentration target adjusted for toner break-in in the developer structure; a feed back dispense unit receiving the adjusted toner concentration target and transmitting a feedback dispense command; and a total dispense unit receiving the feed forward dispense command and the feedback dispense command, and outputting total dispense command to the dispenser, which dispenses the toner to the developer structure in accordance with the total dispense command.
