ABSTRACT:
An electrical circuit provides an indication of the relative positioning of a sensor with respect to sensed indicia borne by documents traveling proximate the sensor. The circuit includes a first clock (10), a sensor switching circuit (30) which determines when the indicia is sensed, and means for determining whether the indicia is read at an acceptable time between successive first clock (10) pulses in order for the sensor to be properly positioned with respect to a document.
