Cambridge will use ImageCast vote tabulators for the first time in a Sept. 4 primary.

For the state primary being held Sept. 4, the last day to apply for an absentee ballot is Friday, between 8:30 a.m. and 5 p.m. Absentee Ballots are available at the city’s Election Commission office, 51 Inman St., Mid-Cambridge. There’s also an online voter registration system at registertovotema.com for applications, address updates or changes of party affiliation. (If you don’t have valid ID, you can use the online system to create an application to print, sign and mail or bring to commission offices.

The primary will be the first using new ImageCast vote tabulators, which commissioners call “similar to the AccuVote system used in past elections” but more user friendly and with new features that reassure voters if “their ballot has been cast successfully or if a ballot error has been detected. If an error is detected, the voter will be provided with the option of having the ballot returned to them to make the correction or to cast the ballot without correction.” Election workers have been trained to help voters if needed, according to a Wednesday press release.
