A method of recording events in a printing machine having a plurality of subsystems. The recorded event corresponds to selected information generated as a result of an event occurring at one of the plurality of subsystems. The log event is communicated to a logging service. A log event file is created from the event information received at the logging service. The log event file is arranged in a file arrangement having a log event record. The log event file is translated to place the log event file in a readable output form.

Method for logging data in an electrophotographic printing machine

An electronic image processing apparatus includes a controller and a plurality of resources in an arbitrary configuration. Each of the resources provides an associated processor storing data related to operational capabilities of the associated resource. The controller is adapted to dynamically configure the image processing apparatus to operate in accordance with the the operational capabilities of each of the processors by defining job requirements as a combination of images defining a set of sheets and specifying compilations of sheets. The job requirement is converted into an assembly tree relationship for merging into additional assembly trees for formulating the job requirement. The controller responds to the data related to the operational capabilities of each of the modules and to the the assembly tree relationship of images, copy sheets, and compilations of copy sheets for providing a production tree relationship of the operational capabilities of the modules including timing relationships for operating the image processing apparatus. The production tree relationship further permits arbitrary definition of a job requirement into a first segment independent of the capabilities of the modules and a second segment dependent upon selected capabilities of selected modules to allow the image processing apparatus to be partially configured based upon operator entered constraints. This technique further allows adaptive control of selective diagnostics.

Partial or untimed production trees to specify specific output terminal

An apparatus and associated method for controlling the operating speed of a photoreceptor within an electrostatographic printing machine having a belt type photoreceptive member for recording a plurality of latent images thereon. The process provides automatic reconfiguration of the electrostatographic printing machine control system to determine appropriate pitch timing values in response to a measurement of the actual belt speed as measured by the elapsed time for a single rotation of the photoreceptor belt.
