VotingWorks recommends that someone cleans the scanner and calibrates double sheet detection before every election.

Scanner Cleaning

The scanner must be clean to accurately detect marks on ballots. In order to clean the scanner:

Once the scanner is open, you can use cleaning fluid and a microfiber or lint-free cloth to clean the scanner. Dampen the cloth and rub with moderate force on the scanning glass and the rollers:

After cleaning, simply close the following:

Double Sheet Detection

The following steps must be completed by an election manager.

In order to prevent voters attempting to scan two ballots at once, VxScan has a double sheet detection feature. To manage double sheet detection, navigate to the Scanner tab of the election manager menu.

Select Calibrate Double Sheet Detection to begin calibration. Follow the instructions on screen. You will need two sheets of blank paper that have the same paper weight as the ballots for the election.

The Disable Double Sheet Detection feature is used to disable the ultrasonic sensor in the event that it fails and improperly rejects single sheets as multiple sheets. If VxScan stops taking ballots or repeatedly displays the Ballot Not Counted - Multiple sheets detected error message, contact customer support. This setting should only be used if advised by the VotingWorks support team.

To confirm the scanner is clean and producing clear images, you may either run the or simply start scanning - if streaks are detected in the images, the software will alert the user.
