From the supplier: OMR technology is evolving. The scanners were originally developed in the 1950s with more desktop-sized models entering the marketplace in the 1970s. The original technology was called 'mark sensing' and used a series of sensing brushes in detecting graphite particles on a document that is passed through the machine. Fiber optics similar to those used to read bar codes are now used. A mark is detected by measuring the light reflected from the surface of a document passing under a read-head. Most OMRs include automatic feed hoppers to contain a certain amount of forms so an operator need not be present. Newer OMRs can also read ink marks as well as lead-generated ones. Scantron's Model 8400 Optical Mark Reader transports 3,000 single-sided or double-sided forms per hour. Data is converted to ASCII text compatible with Lotus 1-2-3, dBase, SPSS and Paradox. The OpScan 5 from National Computer Systems offers simultaneous data transfer between a scanner and a computer with a document throughput rate of 3,000 sheets per hour. Colleges utilize OMR technology to process course evaluation forms and schedule media center materials.
