    The back door of the ballot boxes only exists in newer model ballot boxes and is designed to allow the removal of ballots at the end of Election Day or in case of an AccuVote-OS failure (where ballots are transferred to the side compartment). The back door should be kept locked at all times on Election Day.

  • Page 35: Separating Ballots In The Ballot Box

    Ballots drop into only one of the main compartments of the ballot box only if no separation of blank or write-in ballots is specified in the AccuVote-OS Options window in GEMS, or into either one of the ballot box’s two principal compartments if separation is specified. Once a ballot is determined to be blank or contain write-ins, the ballot deflector automatically rotates to cause the ballot to drop into the ballot box’s alternate main compartment.

  • Page 36: Removing Ballots From The Ballot Box

    Shaking a full ballot box may allow ballots to settle, creating more space inside the box. If an AccuVote-OS seems to be jamming on a continuous basis, verify that ballots have not become stacked up to the chute or ballots are not jammed in the chute (look up through the back door into the chute area).
