The image I want to scan is too big for the scanner.
Problem: The image I want to scan is 50 percent larger than
my scanner platen.
Solution: Scan one half at a time, at exactly the same
settings. Then use your imaging application to join
the parts.
The scanned image has jagged edges.
Problem: The scanned image has jagged edges when viewed
on the screen or printed.
Cause: Jagged edges usually occur because of a conflict
between the scan resolution and the output
resolution.
Solution: Choose a preset Scanning Resolution for the
scanning job. Choose a setting for the intended use
of the image. When you choose a preset
resolution, or a custom resolution, the maximum
resolution of the output device should be evenly
distributed by the resolution you select.
