ImageCast X Ballot Marking Device
Each polling place has an ImageCast X ballot marking device designed to aid voters in marking their ballot. The ballot marking device is equipped with audio prompts (in English, Spanish, Mandarin and Cantonese), an audio tactile controller with buttons and braille labels, and contrast and text size adjustments. The ballot marking device is also compatible with personal assistive devices such as puff/sip technology and enables all voters to cast their ballot independently and privately.
The ballot marking device only marks a ballot, it does not count votes. The ballot marking device generates and prints a paper ballot with the voter’s selections.
ImageCast Central Count Scanner
The ImageCast Central scanner is a high-speed digital scanner used to tabulate all cast ballots in Contra Costa County. The scanner captures a full digital image of the paper ballot and the voter’s marks. The images are stored and tabulated by the ImageCast Central software.
Logic And Accuracy Testing
Prior to each election every piece of voting equipment that will be used to count or mark ballots is put through a set of logic and accuracy tests to ensure that it is functioning properly and tabulating votes correctly.
Each unit is tested using a pre-marked set of ballot cards to verify that it is functioning mechanically (ballots are fed correctly through belts and rollers without jamming), logically (the unit recognizes the specific election’s ballot), and that it is accurate (the voting equipment reads and reports the correct number of votes expected). Testing of ballot marking devices begins one month prior to the election and lasts for one week. The central scanners are tested around 10 days before the election. All testing is open to the public.
