Abstract
A document processor for transporting documents through a path, detecting flaws thereon by electronically scanning each side of the document, printing selectable indicia only on unflawed documents, and sorting and storing separately the flawed and unflawed documents. The electronically scanned information is compared with a master document stored in a computer memory. As a result of this comparison, outputs are provided from the computer which are indicative of a favorable or unfavorable comparison for controlling the printing and sorting functions.
