2K, Black, Dell 1100, 1110 / Samsung ML-1610, ML-2010, ML-2510, ML-2570, ML-2571, SCX-4521F / Xerox Phaser 3117 Rhinotek premium replacement cartridges beat out the OEMs' in every key area, including price, quality and performance. A recent independent study by the Rochester Institute for Technology (RIT) proved that our premium, graphics-grade toner is blacker and finer than the original and our output is consistently cleaner and crisper. And because we fill our cartridges to capacity, the page yield (the number of printed pages per cartridge) is up 20% better than with comparable OEM products.
