He does, that's why I'm saying Sans is pretty much dead here. The ink from Bendy is able to interact, mess and consume souls upon physical touch, which means that one touch from Bendy and Sans is dead calcium. Not even that, one single drip of ink from Bendy is enough to do the job as we saw with Sammy in the books, and we have to remember that whenever Bendy is around, his ink is all around too since he makes the room to get all covered and messy with ink. That means Sans will be fighting in a inky room that can snap his mind or even consume his SOUL, making things even harder. I'm not even mentioning the fact that Bendy can summon an army of Searchers and Lost ones, creatures that are also made out of the same ink. Sans will have to take care of an entire army of Ink, a room filled with ink, and the Ink demon himself tryin' to beat his calcium ass. It's safe to say he will tire out REALLY fast.
