Abstract

Disclosed is a means for synthesizing MICR symbol signals which are substituted for the output from Standard Signal Reference Documents usually used in calibrating MICR print quality. This is accomplished by microprocessor control of an electrical current in a conductor, in front of an MICR read head gap, thus generating a time variant magnetic field which simulates the process of scanning printed MICR symbols.
