He or any 7th Circuit Judge can request an answer. Rule 5(b) of the internal procedures says he must make that request within 14 days of the distribution of the petition. A request for an answer does not trigger review. Indeed, such a request does not mean necessarily that he will request a vote after the answer, but a request for an answer means the petition has raised the interest of at least one judge. Under the internal operating procedures, a judge then has 14 days after an answer is filed to request a vote and then another 14 days for everyone to vote on the petition. (see "whichever is later"). En banc is not granted unless a majority of the active judges vote for it.
