About Guidelines for Resolution Settings
When scanning, if you set a high resolution (increase the numerical value), the image will be extremely detailed, and if you set a low resolution (decrease the numerical value), the image will be rough.
Guidelines for resolutions to set and the purpose of a scanned image are shown below.
150 dpi
Color printing
Use in a web site
Attaching to an email
300 dpi
Black-and-white printing
Saving images to a computer
If you want to magnify the scanned image and print it, set a resolution higher than the above guidelines.
You can set resolution in one of the following settings.
When using the MF Scan Utility: the [Scan Options] pane of the [Settings] dialog > [Resolution]
When using the MF Toolbox: the [Scan] pane > [Resolution]
When using the ScanGear MF: the [Advanced Mode] pane > [Output Settings] > [Resolution]
NOTEIf you set the output resolution at double, the size of the image data will quadruple. If the amount of data is too high, errors such as insufficient memory could easily occur, therefore set the minimum resolution required for the purpose.
