Image Scanner User's Manual
¡ Prescan
Function: Scanning the whole available area at a low resolution (60, 75, or 100DPI*).
Usage: Use "Prescan" when you want to obtain a quick, low-resolution scanned image. You
can then adjust the scan area so that subsequent scans apply to exactly the part of the
original you want to scan.
*DPI stands for dots per inch and is a measure of resolution. Sometimes PPI (pixel
per inch) is used instead of DPI. The higher the resolution, the finer the detail.
¡ Scan
Function: Scanning a selected area with all desired settings.
Usage: Enter settings such as the scan area, scanning composition, resolution, and so on,
and then scan using "Scan".
Determine the value of the settings based on the original and the output device
(screen, printer, etc.). Even if you scan an image at high resolution, you cannot
output it at high resolution with a low-resolution output device. Scanning an image
at high resolution requires much more memory space and processing time.
