Abstract
An electrophotographic marking machine is described including a first set of data with a plurality of parameters corresponding to a plurality of prior electrophotographic markings or frames. The electrophotographic marking machine further includes a second set of data selected from the first set of data based upon a predetermined set of criteria. In addition, the electrophotographic marking machine has a volatile storage device for storing the first set of data, and a non-volatile storage device for storing the second set of data. A method for assessing operability of an electrophotographic marking machine is also described. The method includes the steps of recording a first set of data including a plurality of parameters corresponding to a plurality of prior electrophotographic markings, storing the first set of data in a volatile storage device, selecting a second set of data from the first set of data based upon a predetermined set of criteria, and storing the second set of data in a non-volatile storage device.
