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 text, as well as overlapping 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 provides more gloss, increases durability, and prevents unwanted fading. On some days, the printer hardly stops. With the 533 MHz dual CPU and 512 MB of standard memory (expandable up to 1 GB) of the CLP-680DW, you can be confident that this printer can handle the entire print volume 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 can easily handle 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. This allows you to use three different media types without wasting time changing paper. With the two-line liquid crystal display and the intuitive compass navigation with 5 buttons on the CLP-680DW, you can easily check the device status, navigate the menu, and access unique features. You can print documents directly from the printer without needing a computer by using the direct USB port located at the front of the device under the control panel.
