Limitations of VBI: 

Certain limitations apply to the Vertical Banding Improvement feature as explained below. 

 

 

1.) Image artifacts may appear in the dark regions of a scanned image when applying this 
setting to non metallic-coated reflective media—see examples below. VBI cannot be used on 
non-metallic media.  

 

 
 
2.) When using Vertical Banding Improvement, extra processing time is required after the scan 
has been completed. The additional processing time can take a few minutes or longer 
depending on your computer system resources, document size and scanning resolution.  
 
3.) When using the Scan button with VBI enabled, there is a several second delay (60 seconds 
or more) before scanning actually starts. The amount of time will vary depending on your 
computer system resources, document size and scanning resolution. 
 
4.) The maximum scanned image pixel size that Vertical Banding Improvement can process is 
83.3 megapixels (83,333,333 pixels). Therefore, make sure to note the image pixel size when 
scanning at higher resolutions (i.e. 1200dpi). Although VBI can support a 1200dpi scanning 
resolution, this feature will not work if the pixel size exceeds 83.3 megapixels. If the pixel size 
is too big, reduce your resolution.
