“Scan source”, “Color mode”, and “Resolution” options of this backend are manipulated from the Xsane main window.
There are three scan methods.
If an original is placed on the ADF, the driver acquires an image from the ADF. If an original is not placed on the ADF, the driver acquires an image from the Flatbed.
Scan an original which is placed on the Flatbed.
Scan an original on ADF. ADF allows users to scan multiple originals and both sides of the original at a time.
The duplex scanning can be set from the Standard options window. Duplex scan is supported only when the scan method is ADF.
Color Mode determines the amount of color information that is preserved from your original document:
Color mode obtains a large amount of color information from the original, approximately 16.7 million. Choose this option if you have a color original that you want to display, print or edit in color.
Use grayscale mode to scan black & white photos, or for scanning color material to print on a mono printer.
Use this mode to scan text or line drawings, i.e. pictures or text containing black lines only, with no colors or shades of gray.
Resolution determines the amount of detail you will see in a scanned image.
You will be prompted to enter a resolution value between 50 and 1200. The higher the value, the greater the detail of the scanned image. In general, it is recommended you set the resolution as low as possible, as the higher the resolution, the longer the scanning time and the larger the file size.
Furthermore, at low resolution settings (100-200dpi), in True Color or Grayscale mode, more color and detail is often in the image than the majority of printers and monitors can display.
The table below contains recommended resolution settings for different document types.
Document type | Resolution |
---|---|
Text (printed) | 300 |
Text (FAX) | 200 |
Text for OCR | 300 |
Black and white or Grayscale image | 150 |
Color photo or Image | 150 |
Suitable for displaying small images on a PC monitor at their original size, e.g. images contained in a presentation or web page. Also suitable for larger images that you will reduce in size to include in a report or presentation.
Suitable for displaying small images which have been increased in size on a PC monitor. Also suitable for printing an image at its original size, on a color or mono printer (up to 720dpi print resolution). Use 200dpi, in black & white scan mode for clear OCR text (larger than 10pt). For smaller text use 300dpi.
When quality is important and a lower resolution is inadequate, choose 300dpi for any size of image and type of use. To determine if the resolution is too low, look for squares in the scanned image. Also use 300dpi in black & white scan mode for optimum OCR results.
Only suitable in specific cases when you require a very high resolution.
Note: The file generated can be very large in size and take up a lot of space on your hard disk.
Duplex scanning can be selected when the scanning method is set to ADF. You can also set the bookbinding position of the document.
Only scans one side of the original from ADF.
Set to Right and Left Binding when the top two sides of the document go in the same direction.
Set to Top Binding when the top two sides of the document are reversed.
The bookbinding position of the document is in the case of the top of the original is placed leftwards.
When setting the top of the original is placed upwards (align the top of the original to the inner side of scanner), the bookbinding position of the document becomes reverse.
When the top of the original places upwards, please set “Rotate preview and scan” of the preview window of Xsane as “270”.
RGB channel is supported.
Selecting a different item (None, Sharpen, Sharpen More) will change the image accordingly.
Remove the mixed color of the scanned image on which the corresponding parts shall be white .
Mask edge areas of the document.
(Erases shaded areas in the document.)
Make text appear clearer.
If checkbox is enabled, text will appear smoother.
Remove the rippled (moiré) pattern that can appear in subtly shaded image areas, such as in skin tones. Also improves results when scanning magazine or newspaper images that include screening in their original print processes.
