Scanning strategies 

When scanning documents, always try the default Image Quality 

settings first.  Select the documents type: line, photo, mixed or colorand 

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.
