Abstract
Commercial establishments that add MICR indicia to commercial instruments usually do so via laser printers that produce a high gain signal. Moreover, commercially printed documents that include MICR indicia can also result in a high gain signal. MICR indicia generated by laser printers are difficult to decode, using conventional DC biasing methods, because the laser-generated MICR high gain signals become clipped. Therefore, in order to decode these distorted signals, the present system processes both low and high gain signals to decode the raw MICR data.
