Abstract
The invention pertains to an optical scanning technique which is capable of reading and accepting a wide range of out-of-tolerance symbols. The technique provides that if a successful scan occurs, the signal circuits maintain a status that indicates a true signal is being processed. However, if an unsuccessful scan takes place the signal circuits introduce a distortion therein in order that the symbol may be read successfully.
