The return produced by the automatic tabulating equipment shall be appended to the tally sheet by the canvassers. The return constitutes a part of the official return for the ward or election district. The municipal clerk shall check the totals shown by the return and, if it appears that there is an obvious discrepancy with respect to the number of votes cast in any ward or election district, the clerk shall have the ballots for that ward or election district publicly retabulated to correct the return. Upon completion of the count, the return is open to the public.
