BASIC SCANNER OPERATIONS
Cropping
Select how to crop scanned documents to output.
Brightness
Sets the brightness of the entire image. Specify the brightness as a number within the range of 1
(dark) to 255 (bright). To brighten the entire image, increase the value of the setting. To darken
the entire image, decrease the value.
Contrast
Sets the contrast between light and shadow of the scanned image. Specify the contrast as a
number within the range of 1 (low [soft]) to 100 (high [sharp]). Increasing this value makes the
contrast sharper.
Fixed Outputs the document in the specified size.
Detect Length Detects the rear end of the document to scan the whole length of the
document. When shorter pages are included in the document, the output
images of them are adjusted to the original size.
Automatic Automatically detects the paper size of the document and outputs in the
original size. In addition, document skews are automatically detected
and corrected to output the image data.
Deskew Corrects document skews after scanning to output correct image data.
