Click to display a preview of the image.

Click to start scanning.

For example, choose Import from Photoshops File menu. In Windows, select TWAIN_32. On a Macintosh, select TWAIN_Acquire. The EPSON TWAIN Pro main window appears. 4. Choose the Document Source, Image Type, and Destination.
EPSON Expression 1680 - 5
For example, if youre scanning a photograph, select Flatbed as your Document Source, 24-bit Color (Std) as your Image Type, and EPSON Stylus Printer (Photo) as the Destination, if youre sending the scanned image to an EPSON inkjet printer. If youre using the optional transparency unit, select TPU for Neg. Film or TPU for Pos. Film as your Document Source. If youre using the optional automatic document feeder, select Auto Document Feeder as your Document Source. 5. Click the Preview button. The READY light on the front of the scanner flashes while its scanning. In a few moments, a scanned image is imported into your host applications window. (If the READY light continues to blink, it may indicate an error condition. See page 4 for more information.) 8. Click Close to close the EPSON TWAIN Pro window and return to your application. 9. If you want, save your image using the Save or Save As options from the File menu of your host application.

Using a Network Scanner

Network scanning involves the following steps:
Click to define the scan area automatically.
The scanner server must be turned on and running EPSON Scan Server. From the client computer, start EPSON TWAIN Pro Network to establish a connection to the scanner server. Only one client computer at a time can connect to the scanner server. (See Starting EPSON TWAIN Pro Network on page 7 for instructions.) Choose the Image Type, Resolution, and other settings you want for your scan. Place your first image on the document table (or in the optional automatic document feeder or one of the optional transparency units film guides). Start the scan. Although this can be done from EPSON TWAIN Pro Network on the client computer, it may be more convenient to press the scanners a Start button or to start the scan from the scanner server. Then you can scan several images with a single trip to the scanner.

A dotted marquee frames the area to be scanned.
You see a preview of your scan in the window that opens. 6. Click the Auto Locate button to automatically define the scan area around the edges of your image. Or adjust the scan area by positioning the mouse pointer over any of the eight boxes around the marquees edge and dragging the box to resize the marquee. Click the Auto Exposure button to automatically set the highlight, midtones, and shadow exposure.
Generally its a good idea to use the Auto Exposure button to obtain the best settings for your scan. If youre not satisfied with the results, see your electronic EPSON Expression 1680 Reference Guide for information about adjusting settings. If you need to remove color cast from your image, use the Gray Balance Intensity feature.
If you want to scan more than one image, place your second image on the document table and press the scanners a Start button again. Repeat this step for every image you want to scan. (The settings you chose for the first image apply to these images too.) When you return to the client computer, your scanned images appear in the host applications window. Close EPSON TWAIN Pro Network to end your connection to the scanner server and allow other client computers to use the scanner.
Some applications, such as Adobe Photoshop LE, automatically close the client computers connection to the scanner server when you press the a Start button. You cant use the a Start button to scan multiple images if youre using these applications.
7. When youve finished making adjustments, click the Scan button.
