For printers as fast and versatile as the Optra series, 4039 10plus and the IBM 3112 and 3116, you should demand big output (let's say as much as 14,000 pages) from your print cartridge. Print at 300, 600 or 1200 dpi and you'll get the same consistent look, thanks to our new printing process that uses Diamond Fine toner which produces the sharpest possible common/images. Choice of two cartridges.
Diamond Fine toner significantly reduces toner particle size for the sharpest possible image. Print on a full range of materials, from plain paper and cardstock to transparencies and labels. Works with Lexmark 4039 10 Plus and Optra 4049 Models L and R Series, Lx, Lxi, Lx+, Lxi+, Lxn+, R, Rx, R+, Rt+ and Rn+. Yields 14,000 pages.
