For the robustness development of electrophotographic systems, a stress noise matrix is needed to allow for efficient and repeatable experimental runs. A complete set of system noise factors includes a list in excess of 40 factors. Simple, intuitive compounding of these noise factors can not be done since the output characteristics for image quality are numerous and their interaction with these noise factors is complex. This paper will discuss the process used to reduce this list of noise factors to two setup conditions that represent noise compounding that significantly stresses the overall system response. This small noise matrix was simple to manage and provided for very rapid and efficient execution of parameter design studies.
