2.5 How to Use the Scanner Drivers
JPEG Quality
You can specify compression levels and image quality for scanning in Color or Grayscale mode.
Sample Ratio
You can specify one of the sample ratios, by which images are compressed, listed in the order of precedence from
highest (listed first) to lowest as follows: YUV 4:4:4 < YUV 4:2:2 < YUV 4:1:1.
The higher the compression rate, the smaller the file size is, but the quality of the scanned image is degraded.
[Imprinter] Tab
You can configure settings for using the imprinter option (to be purchased separately). This tab is not displayed unless the
imprinter option is installed.
