    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: An enhanced toner area coverage (ETAC) sensor may be calibrated to adjust for changes in LED intensity by determining a functional relationship between specular developed mass per unit area (DMA) values and diffuse readings obtained from the sensor. Specular and diffuse readings are obtained from an ETAC sensor that senses reflected light from toner patches generated with incrementally increasing densities on the photoreceptor belt. The specular readings in a particular range and their corresponding diffuse readings are selected for the calibration computations. Reflected ratios are computed from the specular readings and used to determine specular DMAs. The specular DMAs and selected diffuse readings define a set of points for which a functional relationship is determined.

    摘要: An online printing parameter establishment apparatus is used with a xerographic printing device for printing high quality prints given a target value. The xerographic printing device is capable of producing at least one print control patch on a photoreceptor and is capable of sensing a value of the at least one print control patch. The xerographic printing device has a plurality of sets of inherent performance characteristic values. The online printing parameter establishment apparatus includes a controller device and a switch device. The controller device is operative to produce a first database of different ones of the sensed values. Each sensed value is associated with a respective one of the plurality of sets of inherent performance characteristic values based upon the target value. The controller device is also operative to produce a second database of a plurality of control values. Each one of the control values is extracted from a respective one of the sensed values and the associated set of inherent performance characteristic values. Further, the controller device selects one of the control values which is closely comparable to the target value. A method for online establishment of print control parameters to render high quality prints using a xerographic printing process is also described.
