2. SCANNING About the Scanner The scanner component of your unit gives you features you would find in a dedicated scanner. It is fully TWAIN compatible, and can be used both with the Sharp Laser Multifunction Desktop and with other TWAIN-compatible applications. About TWAIN The TWAIN standard defines a software protocol and application programming interface for communication between software applications and image acquisition devices. It provides a simple methodology for connecting TWAIN-compatible applications with TWAIN-aware devices. As a TWAIN-aware device, your unit can be used with any TWAIN-compatible application. Precautions when Preparing and Scanning Originals Use original documents that are as clean and clear as possible. Even with a high-performance scanner like the unit, the quality of scanned images will never exceed the quality of the original. Use clearly focused pictures that have been correctly exposed and printed whenever possible. Choose an image that matches your requirements as closely as possible. Whenever a scanned document is modified, the overall picture quality will be reduced. The retouching process only makes some elements of the picture more acceptable, such as brightness or focus, but the real picture quality is not improved. For example, if you scan an image at too low a resolution, the information left out cannot be simulated later. Always set the scanning conditions carefully before scanning. SCANNING 2-1
