SD460 Digital Duplicator Superior print quality and other technological breakthroughs are the mark of the SD460 Digital Duplicator. Instead of a press roller, this system uses a press cylinder to provide a larger paper press point, ensuring more consistent solid fill. An innovative Paper Gripping Mechanism firmly holds the paper, greatly enhancing accuracy of registration. A new ink system monitors the ink flow to deliver faster drying time and reduced setoff. And what may be the biggest improvement in any model of this class is that it has two distinct paper separation systems installed. One for feeding normal weight cut sheet stocks, and a second for feeding thicker more difficult stocks such as envelopes. Each feed array is selected at the touch of a button, it doesn't get any easier or more efficient. All this comes with the world’s fastest first-copy time for a duplicator: less than 12 seconds.
