I'm taking the pre-req's for the edgeline now. It's a product that has a niche market. The paper feeds from the tray up a verticle transport across the top of the machine, down the other side to a decurler. The decurler bends the paper so it will fit the drum better. A bonding agent first sprayed onto the paper before the ink is applied. It next goes to a dryer and back out to the decurler to be duplexed or sent to the finisher. It's a variable speed printer. Heavy ink coverage may result in it being sent around the drum as many as twelve times until it's dried. It's also much slower with 11x17. The models are CM8060 and CM8050.
