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 Scanner. Table 2
describes the scanning strategies for special original types.
