E-voting machine freezes, misreads votes, U.S. agency says DS200 optical scanner from ES&S doesn't meet federal standards, but remains certified, Election Assistance Commission says.
The little noticed EAC report on the DS200 Precinct Count Optical Scanner in the Unity 3.2.0.0 voting system built by Election Systems & Software (ES&S) was released late last month.
The 141-page Formal Investigative Report (download pdf) highlights multiple "substantial anomalies" in the DS200, including intermittent screen freezes, system lockups and shutdowns, and failure to log all normal and abnormal system events.
For example, the DS200 in some cases failed to log events such as a vote being cast, when its touch-screen is calibrated or when the system is powered on or off, the EAC said.
