If the official ballots at an election precinct at which a voting machine is to be used are not delivered at the time required, or if after the delivery they are lost, destroyed or stolen, the election judges shall immediately notify the clerk or other authority under whose direction the ballots are printed who shall cause other ballots to be prepared, printed or written as nearly in the form of the official ballots as practicable. The judges shall cause the substituted ballots to be used in the same manner as the official ballots.
