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： 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.

摘要： In a xerographic printer for tri-level highlight color imaging, two electrostatic voltmeters (ESVs) are used to interpolate the electrostatic potential at a particular location along the path of the photoreceptor belt. Anomalous ESV readings, such as would be caused by dirt interfering with the ESV itself as opposed to systemic changes in the whole apparatus, are detected by having the printer enter a "test mode" in which test patches having minimal charge are monitored by the ESVs. The low-charge test patches enable noise related directly to the ESVs to be isolated from other possible sources of noise. The noise which results from ESV malfunctioning is compensated for when the printer returns to operation.
