I personally do not know of a way to do this. On small, desktop laserjet printers, yes, but not on these big Xerox machines. All three of our machines have a large capacity drawer, which in the case of 20lb offset paper will hold close to 2,000 sheets. That may be the way for you to go; get yourself a high capacity tray. I have no idea if the 7545 has that option, but maybe you could look it up here on Xerox's site.
Sorry I couldn't be more of a help. Maybe someone from Xerox can answer this?
