The Lexmark CS820de colour printer brings production-level performance and quality to the office, with the most advanced imaging technology available. A 1.33 GHz quad core processor with 1 GB of standard memory gives the CS820 Series a powerful print controller. Professional colour features include ultra-sharp 4800 Colour Quality, PANTONE calibration and spot colour replacement for repeatable colour accuracy even with critical corporate identity elements. Lexmark-exclusive Embedded Solutions Framework (eSF) makes the printer programmable to meet the needs of each customer and industry. Several software solutions are included, and more can be added. Expand your output capabilities with standard input capacity of up to 650 pages (expandable to 4,500), an optional inline staple finisher, and the broadest media weight range possible - from tissue-thin paper to thick card stock. The CS820 Series' 10.9-cm (4.3-inch) colour touchscreen features an ultra-smooth surface that can be activated by almost anything, including pens, fingertips or nails - without pressure or direct skin contact. Save money, paper and energy with efficient power management, automatic ColourSaver toner usage reduction, default duplex printing and low per-page carbon footprint.
