Patent attributes
The disclosed method identifies potentially faulty sheets that were printed when the parameters were outside the predetermined normal parameter range and maintains one or more locations of the potentially faulty sheets within the stacks of sheets. If one or more of the stacks of sheets contain one or more of the potentially faulty sheets, the method prints one or more printing fault cover sheets and outputs the printing fault cover sheets to the stacks of sheets that contain the potentially faulty sheets. The printing fault cover sheets identify the locations of the potentially faulty sheets within the stacks of sheets. By providing the printing fault cover sheets and continuing the printing operation, the method can be set to stop the printing only for printing parameters that physically prevent printing, and not for printing parameters that only affect printing quality, thereby maintaining high productivity while still allowing the user to easily locate sheets that potentially have printing faults.
