Abstract: A printer's paper pile inverter includes two parallel, spaced apart, C-frames held in spaced relationship to each other by a base frame including a plurality of C-frame connecting straps integral with, and extending between the base legs of each of the C-frames. First outwardly extending legs of the C-frames and a pallet lift fork mounted on the base frame are slid under a first pallet supporting a pile of papers to be inverted. A second pallet is inverted and placed on top of the paper pile. A jacking mechanism supported on the base frame of the inverter powers the lift fork to lift the first pallet until the second pallet comes into contact with the under surfaces of second outwardly extending legs of each C-frame.
