Resolution

Resolution is measured in dots per inch (dpi). The higher the resolution, the more
detailed the image and the more memory and drive space the image will use.
To conserve computer memory and still receive good image quality, we
recommend the following settings.
Document to be scanned
Text (for printing)
Text (for faxing)
Text (for OCR)
Black and white or gray image
Color image or photo
· These values are only recommendations and should be raised if the
resulting image is rough or you need to view fine details.
· To scan a large-size color image with a higher resolution (usually over
600 dpi) increases scan time and file size substantially and requires
huge system resources. Therefore, a higher resolution for color
scanning is recommended only when you scan a small area.

Raising the brightness increases the amount of white in an image, making it
appear more washed out. Lowering the brightness may help you read light or faint
text.
