Depending on the documents 
scanned, the color of documents  
may not be scanned properly. For  
example, the color of a highlighter 
pen may be scanned lighter than it 
appears.  
Setting the value for Chroma 
higher in the scanning conditions 
may solve this problem.

scanned documents.  
The scanning glasses are dirty.

There is noise or wave patterns  
(moire pattern) on the scanned 
image.  
The scanning resolution settings, 
combined with patterns within the 
scanned image, may cause this 
problem.  
Change the scanning resolution, 
and perform scanning again.  
The sound made by paper being 
ejected is higher than usual when 
you scan short documents.  
If the length of documents are less 
than about 148 mm (5.8 in.),  
feeding speed control will be  
activated for exiting documents; 
this is normal behavior.
