JOB SCHEDULER DIAGNOSTICS

A reproduction machine having image processing means for forming a image, a controller for directing the operation of the image processing means to complete a job reproduction run, the controller including a random access memory for storing machine status information during a machine cycle down interruption prior to the completion of the job reproduction run, a disk memory, and means for detecting controller faults, the method of saving the status information in the random acess memory including the steps of routinely loading machine status information into the random access memory at a machine cycle down, detecting a pre-determined controller fault causing a machine cycle down, and upon detecting said pre-determined controller fault, automatically transferring the machine status information from the random access memory onto the disk memory.
