Wyo. Stat. § 22-12-113: Setting of registering counters.

The judges shall see that all registering counters are set at zero (00000) and that the voting machines are in proper condition. If the machine is equipped with a mechanical or photographic printout device, the election board shall determine that counters are set at zero (00000) by using the printout device. Any count on a machine shall be noted and certified by the judges to permit subtraction of this count when votes are canvassed.
