Electronic control means for a paper handling and counting machine. An LED array provides a visual display of the number of paper documents counted during either normal counting or "batching" operations. The LED display is utilized to the exclusion of additional display devices for providing an indication of a jam condition in the event of a jam by "flashing" the zero decimal digit. A similar indication is artificially created upon turn-on of the machine. When operating in the "batching" mode the LED array, in addition to providing a visual display of a completed batch count, will display a partially completed batch count in a flashing manner. The "jam-type" display is also activated whenever the batch control selector switch is switched from the "count" mode position to any batching mode position. Means are also provided to abruptly stop the drive source for the machine upon the occurrence of a jam condition and also to abruptly stop the drive source for the machine upon the completion of a batch, said abrupt stoppage being accomplished by dynamic braking means. A "leading zero" detection circuit blanks unnecessary zeros from being illuminated.
