Quality control Signal strength Signal strength or level is the relative ability of magnetic ink characters to generate a signal in an electromagnetic sensing device. The signal strength is a percent of a nominal value for each character. The ANSI specification is 50% to 200% of the nominal specified peaks signal for each character. NOTE: Under normal conditions, the signal strength of a Xerox MICR printing system does not require measurement unless some degradation of MICR quality is observed during inspection. Information on MICR signal level measurement is provided here for those customers who have access to magnetic signal strength test equipment. As a document passes over the read head of the reader sorter, the magnetized particles in the MICR ink cause a flux change within the windings of the read head, changing the output voltage. This voltage passes through an amplifier and is translated into readable signals that can be recognized and input to a computer. Each MICR character has a nominal signal strength and wave shape. If the level is either too high or too low, the reader sorter is not able to properly identify the characters. Generic MICR Fundamentals Guide 6-17
