3 Document Quality

Scanning strategies

When scanning documents, always try the default Image Quality settings first. Select the documents type: line, photo, mixed or color and use the Original, Type, Normal, Line, Photo or Color default settings for that type. Color is a Scan-to-Net feature and only available in SCAN mode. These settings have been designed to give the optimum image quality for most documents.

If you have a special original type, you may want to try some of the advanced image processing features available on the Scan System. Table 1 describes the scanning strategies for special original types.
