The ImageReader PowerScan is capable of a maximum resolution of 9600dpi (600x600 Optical). However, if you try to scan at 9600 dpi, be very aware the resulting file size will be astronomically Huge.
You should match your scanning resolution to the purpose of your image or scanning task. Some software has specific requirements for resolution for specific scanning tasks (refer to your software manual for this information or below for some general guidelines). Avoid exceeding the recom- mended resolution settings for your scanning task.
You can adjust the resolution by selecting one of the predefined resolutions (75, 100, 150, 200, 300, etc, to 9600) from the drop down menu or by choosing custom.
Custom Resolution
After you select custom, a window will appear with 2 slide bars. You can adjust the resolution by moving the slide bars. One slide bar governs the vertical and the other the horizontal resolution. If you have Sync checked, the bars will move as one & give you a much more even image.
The resolution has a direct impact on the scanned image file size. Adjusting to a higher resolution setting will result in an increasingly larger file size. Increased demands on your computer resources due to
Some scanning applications only support specific resolutions. Refer to your application User’s Guide for supported resolutions.
