SCAN METHOD
Select how you want to scan on the Scan Method drop-down
menu.
>
Simplex/One-page—use this setting if you are using the
automatic document feeder (ADF) to scan a single-page
document at a time.
>
Simplex /Multi-page—use this setting if you are using the
automatic document feeder (ADF) to scan batches of singlepage document at a time.
>
Flatbed—use this setting if you are using the flatbed to scan
one page at a time.
DETERMINING YOUR RESOLUTION
Proper control of the resolution obtains satisfactory detail of
scanned images. Resolution is measured by dots per inch
(dpi). Normally, the higher the resolution the larger the
image file size will be, but at higher quality.
Greater resolution requires more time, memory and disk space. There
is a limit beyond which the resolution will not produce much visual
improvement, but will make your files more unmanageable.
Resolution: Left = 50 dpi
Right = 100 dpi
An A4 size color image scanned at 300 dpi at True Color mode
consumes approximately 25 MB of disk space. A higher resolution is
recommended only for a small area at True Color mode.

The following table offers a suggestion to help you choose an
appropriate resolution.
IMAGE TYPE
Line Art
Color Picture
OCR*
RESOLUTION (DPI)
200
100
300
*OCR: Stands for Optical Character Recognition, the process to
convert an image to a text format.
SELECTING A PROPER IMAGE TYPE
Select the most appropriate image type depending on your
application.
LINE ART (BLACK AND WHITE)
Line Art presents the image in black and white only and there are no
intermediate shades of gray in between. That means each pixel of the
image is 100% black or 100% white. Line art is the best choice of
image type if you want to scan text, pen or ink drawing. Since only 1bit of black or white information is required for each pixel*, the disk
space required for saving line art images is only about 1/24 of that
required to save 24-bit true color images.
*Pixel: A combination of two words: picture and element, a pixel is a
single dot on a computer display or in a digital image.
HALFTONE
In addition to the black and white display, Halftone simulates
greyscale by using different sizes of dots. When viewed at a distance,
the image looks like a gray image yet it consumes the much less disk
space. Newspapers generally use halftone images. Since halftone is a
type of black and white image, the disk space required is 1/24 of that
required to save a 24-bit true color image.

8-BIT GRAY
A single-channel image consists of at least 256 shades of gray. An 8bit scanner produces a greyscale image with 1024 shades of gray
between pure black and pure white. Choose this option if you are
scanning black-and-white photographs.
With 8 bits of color information per pixel, the file size of an image is
eight times larger than a Black and White image and 1/3 the size of a
24-Bit Color image.
8-BIT COLOR
An 8-Bit Color image provides 256 color hues in the image. The file
size of a 256 color image is 1/3 the size of a 24-Bit Color image. Slight
banding will be visible in areas which contained graduated color.
24-BIT COLOR
A 24-Bit Color image consists of three 8-bit color channels. The red,
green, and blue channels are mixed together to create a combination
of one billion colors which give a more true-to-life quality to the
image. Choose 24-Bit Color if you are scanning color photos.
ENHANCING YOUR IMAGE
BRIGHTNESS
Adjusts the lightness or darkness of an image. The higher the value,
the brighter the image.
USER INTERFACE > 33
GB.book Page 34 Monday, September 30, 2002 6:16 PM
CONTRAST
Adjusts the range between the darkest and the lightest
shades in the image.
The higher the contrast, the bigger the difference between
different shades of grey.
INVERT IMAGE
The invert command reverses the brightness and the color in
the image, producing a negative image. For color images,
each pixel will be changed into its complementary color with
the Invert command.
