Settings in the Scanner Window
Resolution:
Resolution: Select the scanning resolution from the Resolution drop down list. Higher resolutions
take more memory and transfer time, but can achieve a finer scanned image. You can choose:
◆
100 x 100 dpi
◆
150 x 150 dpi
◆
200 x 200 dpi
◆
300 x 300 dpi
◆
400 x 400 dpi
◆
600 x 600 dpi
◆
1200 x 1200 dpi (Black & white, Grey [Error Diffusion]. True Grey and
24-bit colour only)
◆
2400 x 2400 dpi (Black & white, Grey [Error Diffusion]. True Grey and
24-bit colour only)
Colour Type:
Black & White: Set the Colour Type to Black & White for text or line art.
Grey Scale: For photographic images, set the Colour Type to Grey (Error Diffusion) or True Grey.
Colours: Choose either 256 Colour, which scans up to 256 colours, 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.
Size:
Set the Size to one of the following:
◆
Letter (8 1/2 x 11 in.)
◆
A4 (210 x 297 mm.)
◆
Legal (8 1/2 x 14 in.)
◆
A5 (148 x 210 mm.)
◆
B5 (182 x 257 mm.)
◆
Executive (7 1/4 x 10 1/2 in.)
◆
Business Card (90 x 60 mm.)
◆
Custom (User adjustable from 0.35 x 0.35 in. to 8.5 x 14 in.)
After you select a custom size, you can adjust the scanning area further by using the left mouse
button to drag the dotted outline of the scanning area. This is required when you want to crop an
image when scanning.
To scan business cards, select the Business Card (90 x 60 mm.) size setting and place the business
card at the top centre of a carrier sheet.
When scanning photographs or other images for use in a word processor or other graphics
application, you should try different settings for the contrast, mode and resolution to see which
settings best suit your needs.
Custom:
This section displays the size you selected. To adjust the scanning area size to business card size
automatically, check the Business Card Size box.
