Using the Start Button gives step-by-step instructions on setting up and using your scanner’s Start button for one-touch scanning. Troubleshooting provides solutions to problems you may encounter. At the end, you’ll find a Glossary and an Index. Cautions, Notes, and Tips You’ll find this information throughout your manual: Cautions must be observed to avoid damage to your equipment. Notes contain important information about your scanner. Tips contain additional hints for better scanning.
Basic Scanning EPSON Scan! II (Macintosh only) is a TWAIN-compliant application supplied with EPSON TWAIN in case you don’t have a TWAIN-compliant program for scanning. For best results, use one of the TWAIN-compliant applications that came with the scanner instead. See Using EPSON Scan! II for instructions on scanning with EPSON Scan! II.
Starting EPSON TWAIN Follow the steps in this section to start EPSON TWAIN from your application software. The steps may vary, depending on your application. If you start your application software before turning on your scanner, the software may not work properly. The steps in this section cover scanning with common TWAIN-compliant applications. Other applications, such as PhotoDeluxe, use different scanning steps.
One of the EPSON TWAIN windows appears. Easy window Advanced window The screen examples in this book are from EPSON TWAIN for Windows. The screens for Macintosh look a bit different, but they contain the same options. Any exceptions are noted in the text. Basic Scanning The first time you start EPSON TWAIN, you see the Easy window. After that, you’ll see the window that was open the last time you closed EPSON TWAIN. To switch between the windows, click the Easy or Advanced button.
Selecting Basic Settings Document Source settings for optional equipment appear in the list only when that option is installed. If you’re scanning positive, reflective originals (such as a photograph) with the optional transparency unit installed, be sure to turn off the transparency unit. Then select Flatbed as the Document Source option. For most scans, you need to check four basic settings: Document Source, Image Type, Destination, and Resolution (Advanced window only).
2 You must select the correct Image Type setting each time you scan. These image types automatically select other TWAIN settings that are the best for your type of image and set the ranges for your Image Controls. Select one of the following options: To view the default settings for the Image Type you selected, click the Image Type button. You can also change the settings for these options or save your own custom Image Types. See Customizing Image Types for more information.
3 Now select the output device where you want to display or print your scanned image from the Destination list. These destinations automatically select resolution and sharpness settings appropriate for the output device. Select one of the following options: To view the default settings for the Destination you selected, click the Destination button. You can also change the settings for these options or save your own custom destinations. See Customizing Destination Settings for more information.
4 The Image Type and Destination settings you choose automatically select the correct Resolution setting for your image. With applications that let you select ICM, sRGB, or ColorSync profiles for your printer, you’ll get great printed output when you scan using ICM/sRGB (Windows 98) or ColorSync (Macintosh). See Configuring Preview and Color Options for details. If you need to change the resolution, click Advanced to open the Advanced window, if necessary.
Previewing Your Scan You can preview your image in the Advanced window to see the effects of your settings before scanning. Previewing also allows you to determine the width and height of the scanned image and the final file size. You cannot preview an image that exceeds your system’s available memory or disk space. Although the preview image changes when you modify settings, the settings don’t affect the image until you scan it. In the Advanced window, click the image area.
Using Marquees A marquee is a frame around an entire image, or a portion of an image so you can scan only the most important part. To create a marquee, follow these steps: If the mouse pointer doesn’t change to a cross hair, click the Preview button again. You can save different sets of settings for your marquee and then batch scan all the variations. See Batch Scanning for details. 1 Move the mouse pointer over the preview image; the pointer becomes a cross hair.
Adjusting a Marquee To resize a marquee, place the mouse pointer over its edge; the pointer changes to a double-headed arrow. Click the mouse button and drag the box up, down, sideways, or diagonally to the size you want. To resize a marquee and retain its width-to-height proportions, hold down the Shift key as you drag the edge of the marquee. To move a marquee, place the mouse pointer anywhere in the marquee image area; the pointer changes to a hand.
Advanced Scanning The instructions in this chapter tell you how to perform these advanced scanning operations: ◗ Scanning Transparencies ◗ Scanning with the Auto Document Feeder ◗ Customizing Image Types The screen examples in this book are from EPSON TWAIN for Windows. The screens for Macintosh look a bit different, but they contain the same options. Any exceptions are noted in the text.
Scanning Transparencies If you’re scanning positive, reflective originals (such as a photograph) with the optional transparency unit installed, be sure to turn off the transparency unit. Then select Flatbed as the Document Source option; see Selecting Basic Settings for instructions. When you scan with the optional transparency unit (TPU) installed, you need to select the correct basic settings in EPSON TWAIN.

Adjusting Source and Target Image Sizes Sometimes the values you select may be rounded up or down to retain the proportions of your image or marquee. The width and height settings are ignored if you scan without first previewing the image. If you enlarge your target image size by scaling or selecting a larger Target size, be sure to increase the Resolution setting by the same proportion to retain your image quality. See Selecting Basic Settings for instructions on changing the Resolution setting.
Scaling the Image The Scale field indicates the amount by which an image is enlarged or reduced during scanning. The range of the possible scale values depends on the Resolution setting. If you enlarge your target image size by scaling it, be sure to increase the Resolution setting by the same proportion to retain your image quality. See Selecting Basic Settings for instructions on changing the Resolution setting.
Using Auto Exposure Auto Exposure is automatically enabled when you scan from the Easy window. Auto Locate is automatically enabled if you click the Scan button without previewing the image, unless you’re scanning with the ADF and Text Enhancement Technology is turned on (see Customizing Image Types for details on the Text Enhancement Technology feature). Advanced Scanning Click the Auto Exposure button in the Advanced window to automatically adjust the image exposure.
If the document table contains more than one image, select the target image by dragging the mouse pointer across it to create a rough marquee (see Using Marquees for instructions). Then click the Auto Locate button. The marquee is placed exactly around the target image borders automatically.
Adjusting Image Controls Use the Image Controls to adjust the following settings: ◗ Exposure Auto Exposure overrides any Image Controls setting you select. You can’t use the Image Controls when Text Enhancement Technology is turned on (see Customizing Image Types for details).
The Image Controls settings are described in the table below.
Using the Color Buttons You can use the Highlight and Shadow color buttons to select particular colors in the image for use as the highlight and shadow colors. Click a color button and move the mouse pointer over the preview image; the pointer changes to an eyedropper icon. Then click on a color that you want to use as the highlight or shadow color for the entire image. The color box beneath the setting turns to that color.
Each point on the tone curve represents the Output checkbox characteristic to its right. For example, the top point on the curve represents the Highlight characteristic. In addition, the Channels radio buttons indicate the color(s) that the tone curve will modify: red, green, blue, or all three colors. Once you’ve selected the color you want to modify using the Channels buttons, use these methods to change the tones: ◗ Drag points on the tone curve to adjust the tone value.
Using Color Adjustments You can adjust the Gray Balance Intensity and Saturation of colors in a color image using the Color Adjustment tools. Color Adjustment settings are disabled if you click the Scan button without previewing the image. Click the Color Adjustment button in the Advanced window to display the Color Adjustment dialog box: You can’t use Color Adjustment if the Pixel Depth is set to 8-bit Gray or Black & White (see Customizing Image Types for details).
Changing the Gray Balance Intensity The Gray Balance Intensity setting adjusts the gray tones in the image to appear more neutral. You may need to adjust this setting if the three colors that are mixed together to form the neutral gray are unbalanced. For example, if a photograph has an undesirable green color cast caused by fluorescent lighting, you can select a greenish area in the photo and adjust the intensity to achieve the correct colors.
Saving Custom Settings You can save a custom set of all the EPSON TWAIN settings for your scan so you can easily select it when you perform a similar scan later. You can even save different settings for the same image or marquee and scan all of them at once; see Batch Scanning for details. Click the Settings button in the Advanced window to display the Settings dialog box: User defined settings list current settings The currently selected EPSON TWAIN settings are listed on the right.
Batch Scanning To quickly scan one image or marquee with a variety of different settings, you can perform a batch scan.

Sometimes an error condition may cause the computer to display a message telling you that your scanner is not recognized. If this happens, turn the scanner off and then on again; then restart your computer and try again.
You have trouble batch scanning. Problem Solution Your application program doesn’t support batch scanning or you don’t have enough system memory. Some applications don’t support batch scanning. When you try to batch scan or use the optional auto document feeder with this type of program, you get an error message or the system locks up. Check the program documentation and, if necessary, use another program for batch scanning. You also may not have enough system memory for the batch scan.
Problems Using the Start Button You see the message “No Push button scanner detected.” Problem Solution Scanner monitoring doesn’t detect the scanner. The EPSON Scanner Monitor periodically checks on the status of your scanner to make sure it’s ready. Sometimes the scanner check occurs when your system is processing other information and the scanner is not detected during that particular check. (You may see this message anytime, not just when you press the Start button.
Problem Solution PageManager is not installed or the scanner monitor isn’t pointing to it. Make sure you installed PageManager correctly, as described in the Scanner Basics book. Also make sure the scanner monitoring utility still points to PageManager as the target application for Start button scanning. See Enabling Scanner Monitoring for instructions.
Problems with Image Quality Images are very dark and without details. Problem Solution Some EPSON TWAIN settings may be set incorrectly. Make sure the Destination (output device) setting is set to Screen/Web. If you selected a printer as the Destination setting, the image may more closely match the original when printed, but not when displayed on the screen. Change the Exposure, Tone Correction, and Shadow settings to lighter values and scan the image again.
Color is patchy or distorted at the edges of the document. Problem Solution The document isn’t placed correctly on the document table. If the original is very thick or warped at the edges, the edges of the image may be discolored. Cover the edges of the original with opaque paper to avoid interference from outside light. If part of the original is outside the document table, the edge may be discolored. Change the position of the original. The image is faint or out of focus.
The colors on the monitor seem different than the original image or printed image. Problem Solution Your monitor may not be calibrated correctly. Depending on your monitor, its resolution/color settings, and your EPSON TWAIN settings, the screen colors may be different from the original colors. This may be normal, especially if the colors in the printed image more closely match the original. Make sure you have correctly calibrated the screen as described in Using the EPSON Screen Calibration Utility.
The printer can’t print the image, or the printout is garbled or isn’t an image. Problem Solution Your printer and computer may not be securely connected. Check that the printer is properly connected to the computer and is correctly set up; see your printer manual. Your software is not installed correctly for your printer. Check that your application software is properly installed and set up for your printer; see your application software manual.
Moiré (crosshatch) patterns appear in the scanned image. Problem Solution You have scanned a document with halftone patterns. To minimize moiré patterns, try the following: ◗ Place a transparent sheet between the document and the document table to slightly unfocus the image. ◗ Move or angle the document slightly. ◗ Adjust the Sharpness setting to a lower value to unfocus the image. See Customizing Destination Settings for more information. ◗ Change the Target image size setting slightly.
