Installing a duplex unit
The duplex unit attaches under the MFP, below the standard tray and above any drawers.
Place the duplex unit on top of any installed drawers or the table or MFP cabinet where you plan to use the MFP.
The tab, round peg, and square holes on top of any drawer help you position the duplex unit so the edges are 
aligned properly. Make sure it is securely in place.
