One other thought. RX680 is capable of copying an image directly from scanner to disc without using the computer. Do try this to eliminate the possibility of a computer/software issue. Just pop a labeled disc or photo in the upper left corner of the scanner, raise the print tray and follow the prompts on the printer LCD screen. If this won't work, seems very possible that you need a replacement.
@Bob: you'll be glad to know that the 680 won't and can't eject a disc from the back. Can shove this one right up against the wall. And get that thing out of the box already and test it before it gets hard to return a defective one:bigsmile:.
