Resolution
2
You can choose a scanning resolution from the Resolution drop-down list. Higher resolutions take more
memory and transfer time, but produce a finer scanned image. The following table shows the resolutions you
can choose and the available colours.
Scan Type
2
„ Black & White
Use for text or line art.
„ Grey (Error Diffusion)
Use for photographic images or graphics. (Error Diffusion is a method for creating simulated grey images
without using true grey dots. Black dots are put in a specific pattern to give the appearance of grey.)
„ True Grey
Use for photographic images or graphics. This mode is more exact because it uses up to 256 shades of
grey.
„ 256 Colour
Uses up to 256 colours to scan the image.
„ 24bit Colour
Uses up to 16.8 million colours to scan the image.
Although using 24bit Colour creates an image with the most accurate colour, the image file will be about
three times larger than a file created with 256 Colour. It requires the most memory and has the longest
transfer time.
Reduce Noise
2
You can improve and enhance the quality of your scanned images with this selection. The Reduce Noise
setting is available when using 24bit Colour and scan resolutions of 300 x 300 dpi, 400 x 400 dpi or 600 x
600 dpi.
