Scanning from the Manual Mode / Using the Preview Window

Overview of the Preview Window

Before you scan an image, you can preview it in the Preview window to see the effects of most EPSON TWAIN settings, and to make additional image adjustments. Clicking the Full Preview button starts prescanning and previews the image. See Using the Full Preview Button.

EPSON TWAIN offers two preview methods: Preview and Thumbnail preview.

Note:

See Making Configuration Settings for information about how to control the preview image quality.

When the Automatic Thumbnail Preview for Film check box in the Preview menu of the Configuration dialog box is selected, thumbnail preview appears in the Preview window if you set the document source for film and then click the Full Preview button.

Preview

When you scan reflective documents or want to modify an image using marquees, use this method. In the Preview window, you can make some complex settings such as Image Type. See Preview.

Thumbnail preview

When you scan transparent materials, use this method. EPSON TWAIN automatically locates the frames of the film and optimizes the exposure for each image, and previews each frame as thumbnail image. However, some settings appear dimmed and are not available. See Thumbnail Preview.
