i got a document scanner that does just that. it is connected to the network and puts files via webdav/smb into a filesharing.
look for a scanner with network interface. if it’s connected via USB, I can imagine it needs good driver/software support which might be missing
there exists a video on YouTube checking exactly that. as far as I remember, a big fan inside the room pushing air outside works best, because the moving air pulls the air around it with it.
like inflating a plastic bag by blowing into it from a few feet is way faster, then putting you mouth to the opening and trying to blow it up like a baloon
