The Samsung ML-3050 series give you complete freedom with 100, 000 page monthly duty cycle and a large toner capacity. The ML-3050's extremely powerful CPU of 400 MHz and memory expandable to 272 MB make for an unbeatable combination for optimal performance and a more efficient and productive work environment. The ML-3050 series carries a maximum monthly duty cycle of up to 100, 000 pages (approx. 5, 000 pages per average work day) - at least five times greater than other competitive brands. Conserve toner and paper with instant-touch Toner Save which boosts toner productivity by 40% (from 4, 000 to 5, 600 pages). An already robust standard yield of 4, 000 pages doubles to 8, 000 pages with the use of a high yield toner, meaning less frequent changes, fewer consumables, and overall time and effort saved. For prompt and easy installation, the ML-3050 series is just four clicks away from printer-ready status with no need to shut down or reboot your PC. The ML-3050 series is among the world's most adaptable, supporting Windows (including Windows XP 64-bit), Mac and Linux operating systems, making them among the most accessible printers on the market.
