High-yield replacement toner and tools that help minimize toner consumption are the Lexmark CS521dn's keys to controlling the cost of color. Built for reliability, performance and security, it prints up to 35 pages per minute and even lets you print in black when the color toner runs out. With its steel frame, robust paper feeding system that reliably handles diverse media types and sizes, standard long-life imaging system, optional tray for up to 1451 total pages of input, and recommended monthly page volume up to 8500 pages, you'll spend less time doing service and more time printing.
