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.

(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.

Starting EPSON Scan Server
EPSON Scan Server starts automatically whenever the scanner server is turned on. When EPSON Scan Server is running, youll see either the EPSON Scan Server dialog box, or the EPSON Scan Server icon on the Windows taskbar. If you need to start EPSON Scan Server manually, click Start, Programs, EPSON Scan Server, and then select EPSON Scan Server. You can quit EPSON Scan Server at any time. Just click the Exit button on the EPSON Scan Server dialog box.
The command you choose from the File menu differs from one host application to another. With other host applications, you might choose Import or Select TWAIN_32 Source, for example.
3. Start EPSON TWAIN Pro Network. If your host application is Presto! PageManager for EPSON, choose Acquire from the File menu. When EPSON TWAIN Pro Network starts, the EPSON TWAIN Pro Network main menu appears and you connect to the scanner server. Since the settings and controls for EPSON TWAIN Pro Network are the same as those for EPSON TWAIN Pro, see Scanning with EPSON TWAIN Pro on page 5 for general scanning instructions. For more detailed information about settings, see the EPSON Expression 1680 Reference Guide on your EPSON Expression 1680 Scanning Tools CD-ROM.
Wait for this message before you exit.

Starting a Scan

Click to exit Before you quit, make sure no client computers are trying to use the scanner. Dont exit if the status area of the EPSON Scan Server dialog box indicates that you are connecting to a client. Wait until you see the message Waiting for connection. If you installed EPSON TWAIN Pro on the scanner server so that you could make a direct connection to the scanner, remember that you must exit EPSON Scan Server to use EPSON TWAIN Pro. EPSON Scan Server disables EPSON TWAIN Pro.

You can start a scan on your network scanner in several ways: You can start EPSON TWAIN Pro Network on the client computer, make your scan settings, and click the Scan button on the EPSON TWAIN Pro Network main window. The scanned image is imported into your host applications window. You can press the a Start button on the scanner to send the scanned image to the client computer that is currently connected to the scanner server. You can click the Start button on the EPSON Scan Server dialog box to send the scanned image to the client computer currently connected to the scanner server.
Starting EPSON TWAIN Pro Network
You connect to the scanner server by starting EPSON TWAIN Pro Network from the client computer. Follow these steps: 1. Start your host application. 2. Select EPSON TWAIN Pro Network as your source, or scanner driver. (You only need to do this step once.) For example, if youre running Windows and using Presto! PageManager for EPSON as your host application, choose Select Source from the File menu. In the Select Source window, choose EPSON TWAIN Pro Network and click Select. If you have a Macintosh and are using Presto! PageManager for EPSON, click File, Select Source, then Select TWAIN Source. In the Select a source window, select the EPSON TWAIN Pro Network icon and click OK.

EPSON Expression 1680 - 7
Stopping a Scan in Progress
You can stop a scan in progress from either the client computer or the scanner server. To cancel a scan from the client computer, click the Cancel button on the Progress bar. To cancel from the scanner server, click the Cancel button at the bottom of the EPSON Scan Server dialog box. To break the connection between the client computer and the scanner server, click the Stop button on the EPSON Scan Server dialog box.
