Kan. Admin. Regs. § 49-10-1
If a voter inadvertently spoils the ballot, he shall return the ballot to the supervisor of his polling place who shall deliver to him another ballot, preserving the spoiled ballot for the time of counting. The counting of the ballots shall take place as soon as the polls have been closed or as soon as it is practical to count the same: Provided, however, That the commissioner may on his own motion through his representative, keep the polls open as long as he deems necessary. The commissioner or his representative may announce the results of the election as soon as the complete results have been tabulated. At each voting station, the commissioner shall furnish a supervisor to supervise the election. The voter shall fold his ballot so that no part of the face thereof shall be exposed and, upon leaving the polling booth, return his ballot to the supervisor at the polling station who shall then deposit the ballot in the ballot boxes. All ballot boxes shall be examined and locked before the opening of the polls, not to be opened until the time of counting. If the election is to take several days, the ballot boxes shall be locked and remain so until the time of counting of said ballots.
