The problem has occurred despite previous training by the county to teach election poll workers how to use the new machines, Stehman said.

"I'm not sure [what happened]," Stehman said. "It's human nature, I think. We did the training," but people can make mistakes.

Stehman said the county election board has "crews on the road" going to polling places to help get the machines back up and running. "We're calling all the Judges of Elections to [inform] them that everyone can still vote on a paper ballot and put it in the emergency slot" on the eScan machines.

That emergency slot stores completed ballots in a locked area until it is time to count votes. Each paper ballot will be hand-counted if the scanners are not repaired by later Tuesday.

"People can vote and their votes will be counted," Stehman said.
