Abstract
Document reproduction apparatus includes a plurality of sensors for acquiring real time diagnostic data. The acquired data is statistically compared to predetermined control limits or reference value(s) to predeict incipient problems before failure occurs so as to functionally and automatically optimize the reproduction apparatus. Operation of the document reproduction apparatus is functionally optimized in real time in response to differences between the acquired data and the predetermined control limits or reference value(s). The optimizing operation may be in response to detection that the acquired data is tending away from nominal by studying statistical variations in the data.
