Scan Type
Brightness
Adjust the setting (-50 to 50) to obtain the best image. The default value is 0, representing an ‘average’.
You can set the level by dragging the slide bar to the right or left to lighten or darken the image. You can also
type a value in the box for the setting.
If the scanned image is too light, set a lower brightness value and scan the document again. If the image is
too dark, set a higher brightness value and scan the document again.
Note
The
Brightness
setting is only available when
Black & White
or
Grey (Error Diffusion)
or
True Grey
is
selected.
Contrast
You can increase or decrease the contrast level by moving the slide bar to the left or right. An increase
emphasizes dark and light areas of the image, while a decrease reveals more detail in grey areas. You can
also type a value in the box for the setting.
Note
The
Contrast
setting is only adjustable when you have selected one of the grey scale settings. It is not
available when
Black & White
and
Colour
settings are selected as the
Scan Type
.
When scanning photographs or other images for use in a word processor or other graphics application, you
should try different settings for the contrast and resolution modes to see which best suits your needs.
Black & White:
Set the Scan Type to
Black & White
for text or line art.
Grey Scale:
Set the Scan Type to
Grey (Error Diffusion)
or
True Grey
for photographic images.
Colours:
Set either:
256 Colour
, which scans up to 256 colours, or
24 bit Colour
which scans up to 16.8
million colours.
Although using
24 bit Colour
creates an image with the most accurate colours, the image
file will be approximately three times larger than a file created with
256 Colour
.
