Fixed thresholding ATP disabled Fixed Processing used for black-and-white and other high contrast documents. A single level is set to determine the black-and-white transition. The threshold is programmable over the entire density range. Fixed thresholding sets Contrast to 0.

These specks increase file compression size and usually contain no image information. Using the Noise Filter on documents containing very fine detail (e.g., the dot on an "i"...
  • Page 33 A-61517 October 2004 Contrast % sets the image contrast by adjusting the difference between black and white, thereby making an image sharper or softer. In a low-contrast setting, the difference between black and white is small, so the image is softer. In a high-contrast setting, the difference between black and white is large, so the image is clearer.
  • Page 34 200 dpi; 80 Threshold; 20 Contrast 200 dpi; 80 Threshold; 100 Contrast 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.

  • Page 41 Cropping values A-61517 October 2004 Cropping allows you to capture a portion of the document being scanned. You can define the cropping area by the x and y offset values, width and length. Cropping options can be used independently with color/grayscale and bi-tonal images and are also front/rear independent.

  • Page 48 For iThresholding, the scanner will automatically determine the value for this. If the value the scanner determined is lower than the one you entered, that value will be used. Therefore, if using iThresholding, it is suggested that you leave the value at the default.

  • Page 49: The Multifeed Tab

    The Multifeed tab A-61517 October 2004 Multi-feed Detection aids in document processing by detecting documents that may go through the feeder overlapped. Multi-feeds can occur due to stapled documents, adhesives on documents, or electrostatically charged documents. Multi-feed Detection combines ultrasonics (amplitude and phase) with physical length detection to virtually eliminate the chance of losing data due to multi-feeds.
  • Page 50 A-61517 October 2004 Document Ultrasonic Monitor scanner will work to determine if more than one document is fed into the transport. Multi-feeds are triggered by detecting air gaps between documents. This allows multi-feed detection to be used with applications containing documents with mixed thicknesses. You may set the Multi-Feed Detection to high, medium or low sensitivity.

  • Page 51: The Options Tab

    Transport Timeout allows you to set a transport timeout value. This value is the amount of time the scanner will wait after the last document enters the transport before the transport timeout action is taken. You can specify a time delay setting from 3 to 30 seconds. The default is 8 seconds.

  • Page 52: The Setup Tab

    The Setup tab is only available when running the Scan Validation Tool, via the TWAIN Data Source. Package the scanner firmware runs your Kodak i100 Series Scanner. The value displayed in the Current field is the version of firmware currently in use by your scanner.

Front and Rear cropping are independent, however, for simultaneous output scanning color/grayscale and binary cropping must be the same per side.
  • Page 66 This option may be used in conjunction with auto cropping where a separate color or binary area to be saved is desired. It is very useful in applications where a photograph, signature, embossment or seal appears in a consistent area for an application (you may want that small area in color and the rest in binary).
