PAPER RECYCLING APPARATUS USING A LASER BEAM

摘要

A paper recycling system for removing ink or toner deposits by ablation with a beam from a laser (10). A paper feeder (28) delivers documents to a pre-processor (32), where a bit map of the deposits is made through optical scanning, and sent to a system control module (52). This bit map is used by the system control module (52) to instruct the defuser (38) to direct and energize the laser beam only at deposits on the paper document (26). A post-processor (44) functions to remove any remaining particles on the document (26) and scans the document (26) to supply information to the system control module (52) for a determination as to whether or not the processed document is acceptable.
