A characteristic amount watching unit watches at least two basic characteristic amounts of the anomaly object, determines whether values of the basic characteristic amounts satisfy a predetermined watching determination condition of any one of predetermined plural anomaly types or not, if it is determined that the values of the basic characteristic amounts satisfy the watching determination condition, determines as an auxiliary characteristic amount for the anomaly object a characteristic amount corresponding to the anomaly type of which the values of the basic characteristic amounts satisfy the watching determination condition, and starts watching a value of the auxiliary characteristic amount. An anomaly type determining unit determines an anomaly type of the anomaly object on the basis of the basic characteristic amounts and the auxiliary characteristic amount currently watched by the characteristic amount watching unit.

Abstract: A front end of a raster image processing (RIP) system decides a starting storage location and a storage hierarchy. The hierarchy dictates where the rendered pages of a job will be stored. At least one page of a first set of pages of a job are stored at a memory for the RIP system. At least one page of a second set of pages of the job are stored in a storage drive when the memory is not available. The type of job also dictates that the rendered pages of the job are stored in the storage drive. Complex pages also are stored in the storage drive while simple pages are discarded. The processing operations are managed so that the print engine is running efficiently.
