Abstract
A digitizer system having a page recognition system and a method of using such digitizer system is disclosed. The page recognition system detects a page number pre-coded on a sheet of paper when the sheet of paper is mounted onto the digitizer system. When a sheet of paper which was previously mounted on the digitizer is re-mounted onto the digitizer, the digitizer recognizes the sheet of paper as having been previously digitized and re-loads the electronic file corresponding to the same sheet of paper. Thereafter, the digitizer records the annotations made by the digitizer operator to the previously digitized sheet of paper.
