Scanning with EPSON TWAIN Pro

1. Start your host application (for example, Adobe Photoshop

LE).

2. Select your scanner driver. (Unless you change your source, you only need to do this step once.)

For example, if you’re running Windows and using Adobe

Photoshop LE as your host application, click File, Import,

Select TWAIN_32 Source. In the Select Source dialog box, select EPSON TWAIN Pro(32-bit). Then click

Select.

If you have a Macintosh, click File, Import, Twain

Select. In the Select a source dialog box, choose EPSON

TWAIN Pro and click OK.

The command you choose from the File menu differs from one host application to another. With other host applications, you might choose Acquire or Select

Source instead of Import.

3. Open the scanner software.

5. Click the Preview button.

Click to define the scan area automatically

A dotted marquee frames the area to be scanned

Click to start scanning

Click to display a preview of the image

For example, choose Import from Photoshop’s 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.

For example, if you’re 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 you’re sending the scanned image to an EPSON inkjet printer. If you’re using the optional transparency unit, select TPU for Neg. Film or

TPU for Pos. Film as your Document Source. If you’re using the optional automatic document feeder, select Auto

Document Feeder as your Document Source.

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 marquee’s edge and dragging the box to resize the marquee.

Click the Auto Exposure button to automatically set the highlight, midtones, and shadow exposure.

Generally it’s a good idea to use the Auto Exposure button to obtain the best settings for your scan. If you’re not satisfied with the results, see your electronic

EPSON TWAIN User’s Guide for information about adjusting settings.

If you need to remove color cast from your image, use the Gray Balance Intensity feature.

7. When you’ve finished making adjustments, click the Scan button.

The READY light on the front of the scanner flashes while it’s scanning. In a few moments, a scanned image is imported into your host application’s window.

(If the READY light continues to blink, it may indicate an

error condition. See page 3 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.

Scanning Color Images

If the colors in your scanned image don’t match those in your original document, try experimenting with the Unsharp

Mask setting. Click the Destination button in the EPSON

TWAIN Pro main window to display the Destination window, and then select or deselect Unsharp Mask.

Selecting Resolution

Resolution refers to how many dots per inch (dpi) or dots per centimeter (dpcm) your image contains. The best resolution for a scanned image depends on the type of image you’re scanning and your final output device.

As a rule of thumb for most images except line art, use a scanning resolution that is approximately one third of your output resolution. For example, use a scanning resolution up to 100 dpi with a 300 dpi laser printer, and up to 200 dpi with a 600 dpi laser printer. For 1440 dpi ink jet printers, such as the EPSON Stylus

®

COLOR series, use a scanning resolution of up to 300 dpi. Try a scanning resolution of

240 dpi for 720 dpi printing.

Keep the following in mind when you choose a resolution:

❏ The higher the resolution you select, the larger the resulting image file will be. For example, an 8.5

×

11-inch original scanned at 300 dpi can produce a 24MB file. The same original scanned at 72 dpi creates only a 1.3MB file. Large files take longer to process and print, so consider the practical limitations of your computer system and hard disk drive when selecting a resolution. To keep your file size manageable, select the lowest possible resolution that gives acceptable quality. (If your final output is for on-screen viewing, you can scan at 72 dpi and reduce your file size.)

❏ If you need to scan at a higher resolution, you can reduce the size of the resulting image file by scanning only part of the image. For information about selecting part of an image, see “Making and modifying marquees” in your electronic

EPSON TWAIN User’s Guide.

Using a Network Scanner

Network scanning involves the following steps:

❏ 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 unit’s 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 scanner’s

] Start button or to start the scan from the scanner server. Then you can scan several images with a single trip to the scanner.

❏ If you want to scan more than one image, place your second image on the document table and press the scanner’s

] 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 application’s 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 computer’s connection to the scanner server when you press the

] Start button.

You can’t use the

] Start button to scan multiple images if you’re using these applications.

Starting EPSON Scan Server

EPSON Scan Server starts automatically whenever the scanner server is turned on. When EPSON Scan Server is running, you’ll 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.

6 EPSON Expression 1640XL 8/00

EPSON Expression 1640XL

You can quit EPSON Scan Server at any time. Just click the

Exit button on the EPSON Scan Server dialog box.

Wait for this message before you exit.

Click to exit

Before you quit, make sure no client computers are trying to use the scanner. Don’t 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.

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 you’re 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.

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

1640XL Online Reference Guide on your EPSON

Expression 1640XL Scanning Tools CD-ROM.

Starting a Scan

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 application’s window.

❏ You can press the ] 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.

IP address of the client computer connected to the scanner server

Click to start a scan from the scanner server

No matter how you start the scan, the client computer must be running EPSON TWAIN Pro Network to connect to the scanner server.

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.
