I agree with Doug's comment in theory. But in practice, the
pollworker is usually called over to investigate the problem. One
problem is that one voter may recalibrate a voting machine
intentionally incorrectly towards the end of a voting session and
thereby mess up subsequent voters. So if a voter recalibrates a
voting machine, there needs to be a mechanism whereby a pollworker to
recalibrate the voting machine prior to the next voter using that
