Previewing and Adjusting the Scan Area
Once you have selected your basic settings and resolution, you can preview your image and select or adjust the image area of the image(s) in a separate Preview window on your screen.
Preview window displays your previewed image(s) in their entirety. You must select the scan area and make any image quality adjustments manually.
 |
Click Preview.
|
Epson Scan prescans your image(s) and displays them in the Preview window.
 |
To adjust the image quality, click the scan area(s) you want to modify and make the adjustments. See Adjusting the Color and Other Image Settings for instructions.
|
Creating a Marquee on a Preview Image
A marquee is a moving dotted line that appears on the edges of your preview image to indicate the scan area.
Note:|
Once you set the scan area using the marquee, it applies to all pages.
Marquee is only available when Single-Sided or Carrier Sheet (Single-Sided) are selected as the Document Source.
|
You can move the marquee and adjust its size. You can create only one marquee.
|
To draw a marquee, move your cursor over a preview image. The pointer becomes a set of cross-hairs.
|
|
Position the pointer in the area where you want to place the corner of your marquee and click. Hold down the mouse button and drag the cross-hairs over the image to the opposite corner of the desired scan area. Then release the mouse button. You see the moving dotted line of the marquee.
|
 |
Do one of the following to adjust the marquee.
|
To move the marquee, position your cursor inside the marquee. The pointer becomes a hand. Click and drag the marquee to desired location.
To resize the marquee, position your cursor over the edge or corner of the marquee. The pointer becomes a straight or angled double-arrow. Click and drag the edge or corner to the desired size.
Note:|
To restrict the movement of the marquee to vertical or horizontal only, hold down the Shift key as you move the marquee.
To restrict the size of the marquee to the current proportions, hold down the Shift key as you resize the marquee.
For best results and image exposure, make sure all four sides of the marquee are located inside the preview image. Do not include any of the area around the preview image in the marquee.
To delete the marquee, press the Delete key.

Before you make adjustments, be sure to click the image or marquee for the area you want to adjust.
