I have Compucover covers for my Epson 4800 printer and my Epson 700 scanner. Topnotch products, highly recommended.
The cover for the printer is a little loose, which turns out to be a huge advantage in that I basically never remove it. For use, I just lift the front and fold it back far enough to expose the paper tray and controls. For access to the roll, I just fold it back farther still.
