"Ban the box" usually isn't an outright ban on all criminal background checks. The thing it's fighting against is a checkbox/question on the initial job application, to prevent use of it as a universal "not even going to talk to you" filter.
Typically, an employer can run a criminal background check in a "ban the box" jurisdiction, but only later in the process (for example: after completing interviews and provisionally deciding this is someone you'd like to hire). There may also be other rules in place about how you can use information from the background check, and what you have to do if you decide to revoke the offer of employment based on the result of the check.
