ABSTRACT:
A system for analyzing pages has a circuit for generating page information, a circuit for determining if the page information represents a blank page, a blank page counter that is incremented if a blank page is detected, a comparator for comparing the blank page counter to a blank page threshold memory, and an error indicating circuit that indicates an error signal if the blank page counter exceeds the blank page threshold and a detect signal is active. The page analysis system detects blank pages within a job and distinguishes between initial blank pages caused by incorrectly oriented original pages within a machine, and intentionally blank pages within the middle of a job.
