The Reset Button - Microtek ArtixScan 120tf Reference Manual

The Reset button

This button brings up the Reset dialog box, where you can specify which AIC
setting you wish to reset by checking its corresponding AIC check box. When
you click the Reset button, the checked AIC settings are restored to their default
values.
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.
Example: If you increased saturation, changed the gradation curve, and then
clicked OK, all the changes are applied, and you exit the AIC dialog box.
