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.
