Failure recovery mechanism for errors detected in a mail processing facility

摘要

The present application relates to techniques and equipment for printing documents, inspecting the quality of the documents and correcting for defective printed material in a document processing environment. The present techniques and equipment detect one or more defective pages in a document and uniquely identify the defective document. Once the defective document is identified, it can be removed from a document processing system while continuing the document processing run for subsequent documents in a mailing.

主权项

1. A method for using print inspection data associated with a roll of paper containing a plurality of printed documents, to control an inserter or wrapper system for removing a defective document contained in an envelope from a mailing, the method comprising steps of:
receiving a data file associated with the roll of paper containing the printed documents at a system controller of the inserter or wrapper system, the received data file containing at least a unique identifier and a print defect indicator linked to the unique identifier for each of a plurality of documents and an indication whether any of the documents is defective in terms of at least print defects generated during printing operations of the document; for one of the plurality of documents, reading the unique identifier printed in an area of the document that is visible through an envelope window following insertion with an image processing device positioned adjacent to an input or output channel of the inserter or wrapper system; determining if the read unique identifier is associated with the defective document in terms of at least the print defects; upon the determination:
diverting an envelope containing a printed version of the defective document on inserter or wrapper system by way of a diverter that is present on the inserter or wrapper system, while continuously processing subsequent documents in the mailing on the inserter or wrapper system; orprocessing an envelope containing a printed version of the defective document on the inserter or wrapper system when no diverter is present on the inserter or wrapper system and subsequently diverting to a reject bin the envelope containing the printed version of the defective document on a sorter system; and creating a data record confirming the removal of the defective document.
