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 2 describes the scanning strategies for special original types.
