ABSTRACT:
An apparatus and control method therefor which compensates differences among individual media in detected signal amplitudes caused by imperfect magnetic ink character printing conditions without requiring an adjustment of amplitude of a received signal amplifier. Preferably, the magnetic ink character detection apparatus of the present invention includes a moving device that moves the magnetic head and/or the medium relative to each other at a predetermined speed; an amplitude detection unit for detecting the amplitude and/or saturation amount of the electrical signals output from the magnetic head; and a moving-speed determination unit for determining the relative moving speed caused by the moving device in accordance with the output from the amplitude detection unit.
