Image Type Choose a grayscale or binary (black and white) scanning format in the
Image Type drop-down list box. Select the format that is best suited to
your application. Grayscale provides better image quality but requires
more scanning time and memory.
Grayscale Binary
NOTE: Additional memory may be required for grayscale scanning,
depending on the selected resolution and paper size. Refer
to the chapter entitled
Memory Requirements for more
information about memory.
Resolution (DPI) 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. This
function sets the resolution of the main scan and sub-scan areas. The
industry standard is 200 dpi (about 8 pixels/mm).
You can choose a preset value in the Resolution box or type the
desired value. The default value is 300 dpi. Following are the available
resolutions:
• Scanner 1500—100-600 dpi (1 dpi/step)
• Scanner 2500—100-600 dpi (1 dpi/step)
NOTE: Changing the resolution affects the Area , Region , Halftone
(Dither), and Barcode settings. Specify the resolution before
you select these functions.
