Resolution or dots per inch (dpi)  indicates the scanning resolution, which largely determines the quality of the scanned image. The greater the resolution, the better the reproduction. However, scanning at a higher resolution also increases scanning time and file size. The industry standard is 200 dpi (about 8 pixels/mm).

Choose a resolution value from the drop down list. The default value is 200 dpi. Available resolutions are 200, 240, 300 or 400.

Polarity  the host computer provides information to the scanner defining whether the image should be stored in standard or reverse polarity. The default polarity is Black on a White background. Reverse polarity is White on a Black background.

Color Table  Not applicable for bi-tonal images. See the next section “Scanning Color Images”.

Toggle Patch  the Toggle patch is a type 4 patch that is used to trigger the scanner to change from the current image stream (bi-tonal) to the alternative image stream (color/grayscale). Available for the i820 and i840 scanners, this provides color-on-the-fly functionality for customers who choose to scan the majority of their documents bi-tonal with the option to switch to color and back when desired. This is the same functionality, which is available on the Kodak Digital Science 3590C Scanner. Select Off, Front Side or Both Sides.

Calibrate  the calibration process includes the imaging chain (color and bi-tonal), the multi-feed detector, and the mechanical transport. This is done using the designated calibration target, which is fed twice; once for front, once for rear. Calibration is not required at power-on as calibration values are stored by the scanner. The scanner prompts the operator via the Operator Control Panel when calibration is required.
