ABSTRACT:
In a system including a plurality of elements, or plurality of subsystems of elements, each performing a process using process control to maintain operation within a latitude of a setpoint and having an output characteristic that contributes to an overall output quality specification of the system, a control method includes setting a desired overall output quality specification, and determining optimum setpoints and latitudes of the plurality of elements, within a range of possible setpoints and latitudes for each element, to achieve the desired overall output quality specification. The control method further includes dynamically re-setting the setpoints and/or re-allocating the latitudes of at least two of the plurality of elements (or subsystems of elements) to compensate for degradation of the attribute caused by variation in the output characteristic of one element within the desired overall output quality specification. The system may be an image forming apparatus, such as a xerographic system, or a modular document processing system. The control method may be stored on a computer readable media.
