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   Resolution (dpi) Text (for printing)   300   Text (for faxing)   200   Text (for OCR)   300   Black and white or gray image   150   Color image or photo   100

· 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.
