• Item names and assignable values will vary depending on the machine.
• The Contrast setting is available only when selecting Gray (Error Diffusion), True Gray, or 24bit
Color from the Scan Type options.
1. Resolution
Select a scanning resolution from the Resolution pop-up menu. Higher resolutions take more memory and
transfer time, but produce a finer scanned image.
2. Scan Type
Select from a range of scan colour depths.
• Black & White
Use for text or line art images.
• Gray (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 a grey
appearance.)
• True Gray
Use for photographic images or graphics. This mode is more accurate because it uses up to 256
shades of grey.
• 24bit Color
Use to create an image with the most accurate colour reproduction. This mode uses up to 16.8 million
colours to scan the image, but it requires the most memory and has the longest transfer time.
3. Document Size
Select the exact size of your document from a selection of preset scan sizes.
• If you select Custom, you can specify the document size.
4. Adjust Image
Click the Adjust Image button to adjust other image qualities.
