The picture below shows my Epson Stylus Photo 2200 printer from the back, with my home-made CD tray just being inserted. Notice that the lever on the left has not yet been raised back to the "print" position.
Thanks to http://www.anestoday.com/epson2200/cdprint.htm for the inspiration to make my own CD printing tray and for the information about the liftable front rollers. (That site doesn't doesn't use the liftable rollers, but I do.)
