What is a MICR Gauge?

A MICR gauge is a transparent plastic ruler for checking the placement of the MICR line. The process for ensuring the correct alignment of the MICR line is to first print a sample check to the check stock you will be using for live checks. Then line up the vertical dotted line on the right side of the gauge with the edge of the check. Be sure the characters in the MICR line fit squarely within each box in the position stated on the specifications you received from your bank.
