To adjust the resolution and sharpness:
1. To use one of the preset resolutions for typical scanned items, click
one of the options in the list.
For example, to set the resolution for scanning a business card,
select Business Card (OCR). That setting is sufficient for your
optical character recognition (OCR) application to read the small
print on a business card.
2. To set the resolution manually, drag the Resolution slider to the left
to decrease the resolution or to the right to increase it.
3. To adjust the sharpness, drag the Fidelity slider to the left to
decrease the sharpness or to the right to increase the sharpness.
You can also type a number directly into the sharpness setting box,
or click the up and down arrows next to the box to increase or
decrease the setting.
To return the settings to their original amounts, click Reset.
The resolution and sharpen panel also includes two advanced settings
for Moire patterns and Fast Scan (JET). Moire patterns are wavy,
rippled lines that sometimes appear on the scanned images of
photographs or illustrations, particularly newspaper and magazine
illustrations. The Fast Scan (JET) option is for compressing JPEG files.
See "About JPEG Compression" on page 26 for more information about
the JPEG compression.
To use the advanced options:
1. Click Reduce Moire to scan the image and limit or eliminate the
amount of moire patterns.
2. Click Fast Scan (JET) to scan the image with a quality setting for
JPEG compression.
Type a number into the quality setting box, or click the up and
down arrows next to the box to increase or decrease the setting.
