Tips:
1. 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
recommended only when you need to scan a small area at True
Color mode.
2. You can also refer to the following table to choose a proper
resolution while applying your image to other application.
