摘要： A method and system for a color xerographic machine determines a lower bound for the ROS power levels so that color defects are not produced by light attenuation from one or more layers of toner particles on a latent image. The method computes a minimum ROS power level for the photoreceptor at its maximum and minimum charge levels. The minimum ROS power level is the level at which the discharge voltage does not drop beyond a maximum discharge voltage difference. The difference is related to a toner particle density that affects color reproduction. The minimum ROS power levels for the minimum and maximum photoreceptor charge levels are used to compute a functional relationship for minimum ROS power levels at other photoreceptor charge levels. Thereafter, the minimum ROS power level function may be used to compute minimum ROS power levels for other photoreceptor charge levels. The computed minimum ROS power levels may be used to control the power levels used during color reproduction performed by the machine.

摘要： A single pass tri-level imaging apparatus and method. Compensation for the effects of dark decay on the background voltage, V.sub.Mod, and the color toner patch, V.sub.tc readings is provided using two ESVs (ESV.sub.1 and ESV.sub.2), the former located prior to the color or DAD housing and the latter after it. Since the CAD and black toner patch voltages are measured (using ESV.sub.2) after dark decay and CAD voltage loss have occurred, no compensation for these readings is required. The DAD image voltage suffers little dark decay change over the life of the P/R so the average dark decay can be built into the voltage target.

摘要： A process control method for color quality control maintains a preselected developed mass per unit area (DMA) of black solid area by adjusting the development field during run-time operation. In order to estimate the DMA of a solid black control patch, which is outside the sensing range of an infra-red densitometer (IRD), an estimation technique is employed which accounts for system changes due to adjustment of the development field. The estimation technique includes generating two or more test patches, using a patch generator, which have DMA readings within the sensing range of the IRD. The DMA readings and corresponding development voltages of the test patches are sensed and used to calculate a developability curve. The developability curve is projected into a region beyond the sensing range of the IRD. From the developability curve, the DMA of the solid black control patch is estimated and employed in a closed feedback loop to return the system to the preselected DMA by adjusting the development field. Development field control provides faster response to toner density changes than toner concentration control, and thus, results in better color quality control.

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 feed forward toner concentration control system and method for replacing toner in each developer structure, which was used to develop a latent image on a photoreceptor belt, in order to maintain toner concentration in at least one developer structure. First and second pixel counts for first and second toner in each sector are received. The first toner mass is estimated based on first pixel counts. The second toner mass is estimated based on second pixel counts. Feed forward dispense commands are generated based on first toner mass estimate and second toner mass estimate to dispense each toner into each corresponding developer structure to replace toner used to develop the latent image on the photoreceptor in order to maintain toner concentration in each developer structure.
