Resolution
A good control of the resolution results a
good detail of an image that scans. The
resolution is measured by dots per inch
(dpi). Normally, the greater the dpi number,
the higher the resolution and the image file
size. Be aware that greater resolution takes
more time to scan, and more disk space for
the scanning image. For your information,
an A4 size color image scanned at 300 dpi at
True Color mode consumes approximately 25
MB of disk space. A higher resolution
(usually means over 600 dpi) is only
recommended when you need to scan a
small area at True Color mode.
Choose a resolution value from the drop
down list. The default value is 200 dpi.
Available resolutions are 75, 100, 150,
200,300, 400 and 600. Or you may choose
your desired value by clicking the box in the
right side of the drop down list and press the
arrow key to select your desired value and
then click the Add button to include it in the
drop down list. Note: The resolution is up to
300 dpi if an imprinter or a MICR reader is
installed or connected to the scanner.
