The Reset Button - Microtek ArtixScan 4500t Reference Manual

The Reset button

This button brings up the Reset dialog box, where you can specify the settings to
be reset by checking the box next to the targeted settings. If you click the Reset
button, the settings are restored to their default values; if you click the Cancel
button, the operation has no effect, and the settings remain in force.
Example: If you changed the tone curve and saturation, then checked the
saturation option in the Reset dialog box and clicked Reset, the saturation setting
of the scan job is restored to its default value. The altered tone curve, however,
remains in effect. If you reset both tools, then both are restored to default
values.
