Samsung's unique ReCP technology (Rendering Engine for Clean Page) enhances the overall quality and intensity of your color prints, ensuring that every printed page looks perfect. It automatically adjusts the sharpness of graphics and texts, and overlaps colored objects to eliminate any white gaps. Our newly developed polymerized toner features smaller and more uniform particles than conventional toner, resulting in sharper lines and more vibrant colors, while keeping the paper smoother. The higher wax content also adds more gloss, increases durability, and prevents unwanted fading. On some days, the printer hardly stands still. With the 533 MHz dual CPU and 512 MB standard memory (expandable up to 1 GB) of the CLP-680ND, you can be confident that this printer can handle all the printing demands of your workgroup. If you want to use thicker paper for printing or copying, that's not a problem. The 50-sheet multipurpose tray and the standard 250-sheet tray easily accommodate papers up to 220 g/m². Additionally, with the optional second tray for 520 sheets, you can increase your total input capacity to 820 sheets, allowing you to use three different media types without wasting time on paper changes.
