At Allen North Information Desk, all 3 scanners should be kept on the shelves at the center of the desk,
on the west side only. 2 will fit on the top shelves (front and back) and one on the 2nd shelf on the back side of that central shelving unit. As soon as I get the chance, I'll make labels for these shelves.
At Allen South Info, the scanner is in the drawer in the small desk along the north wall.
