The Lexmark MS821n features a first page in just 4.5 seconds and output of up to 55 [52] pages per minute. A combination of 1-GHz dual-core processor and 512 MB of memory (upgradeable to 4.5 GB) has the power to handle demanding tasks right now while providing a secure, upgradeable framework for future advances in product functionality. And all two-sided-printing models in Lexmark’s most energy-efficient line of large-workgroup monochrome products ever are rated EPEAT® Silver and ENERGY STAR® (2.0) certified. With new front power button and USB port, 2.4-inch colour LCD/keypad to monitor and configure system settings and single-door access to parts and supplies, it’s easier than ever to get things done. Convenient front access to the paper path means you’ll virtually never have to access the back of the device, allowing placement in or on cabinets. And ADA-compliant trays have push-button sliders and open with one hand, requiring low force and no twisting. With access to input capacity of up to 4400 sheets, replacement toner cartridges that go as high as 15,000 pages, long-life imaging unit and a fuser that may never need replacement, you’ll spend more time printing. Plus, innovations in part replacement and accessibility help you resolve problems quickly.
