Chapter 1 Installing Your Software EPSON Scanning Utilities come with installer software that makes them easy to install with Windows 3.1 or Windows 95. First make sure that the interface cable is connected properly. If you are using a SCSI interface, also make sure the SCSI software has been installed and the interface settings, such as SCSI IDS and terminators, are set properly. Then follow the instructions below to install your software.
5. Choose OK to accept the default pathname, or delete it, type a new path, and choose OK. 6. The next dialog box displays the default Windows directory. If the displayed path is correct, choose OK. Otherwise, delete the displayed path, type a new path, and choose OK. 7. The program copies the files to your hard disk drive and prompts you for diskette 2 as necessary. 8. Then you see the EPSON Scanner Setup dialog box.
10. Click the Test button. If the scanner, interface, and EPSON Scanning Utilities are set up correctly, the scanner scans the image. After a few moments, you see the scanned image in the EPSON Scanner Setup dialog box, as shown below: 11. Click OK to close the EPSON Scanner Setup dialog box. 12. Remove the EPSON Scanning Utilities diskette from the drive. 13. If you are using Windows 3.1, exit and restart it. The program creates an EPSON Scanner program group or folder in Windows.
Using TWAIN With Windows 95 and Photoshop 3.0.4 To use a 32-bit TWAIN data source with Photoshop 3.0.4 and Windows 95, you need to obtain patch files from Adobe to enable Photoshop 3.0.4 to operate in 32-bit mode. Contact Adobe at (800) 87-ADOBE for more information. Once you have the patch files, follow these instructions to install them: 1. Install Photoshop 3.0.4, if you have not done so already. 2. Insert the patch diskette in your diskette drive or copy the files to a directory on your hard disk. 3.
Calibrating Your System Sometimes the colors of your original image do not match the colors you see on your screen and in the final printed output. This is because of the different color processes your scanner, monitor, and printer use to produce color. The scanner and the monitor both create a range of colors by adding red, green, and blue in different proportions and intensities (an additive color process).
Performing Screen Calibration Follow these steps to perform a screen calibration: 1. From the Windows 3.1 Program Manager, double-click on the EPSON Scan! II icon in the EPSON Scanner program group. From Windows 95, click Start and select Programs; then select EPSON Scan! II from the EPSON Scanner folder. 2. Choose Screen Calibration from the Calibrate menu. You see this screen: 3. Look at the display from a distance and adjust the slide bar until the separate rows have the same basic color intensity.
Enabling Screen Calibration Once you have calibrated your screen, you need to make sure screen calibration is enabled. Follow these steps: 1. Start EPSON Scan! II, if necessary. 2. From the File menu, choose Acquire. You see the TWAIN screen. If the screen is fairly small and has an Advanced button, it is the easy screen. Click Advanced to switch to the Advanced screen. If the screen is large and has a Configuration button, it is the advanced screen. 3.
If you have one of these EPSON Stylus@ ink jet printers, EPSON Scan! II provides printer calibration profiles for you so you do not have to create them: EPSON Stylus COLOR EPSON Stylus COLOR II EPSON Stylus COLOR IIs EPSON Stylus Pro EPSON Stylus Pro XL For these printers you simply select the correct printer calibration profile before you scan an image. See “Scanning Using Calibration” on page 2-8.
You see the following screen: 3. From the File Format pull-down menu, select a format your application software can open. If you want to change the location where the file will be saved, use the other pull-down menus to select the new drive or directory. 4. In the File Name field, type the name (such as COLOR1.BMP) you want to assign to the calibration chart file. Make sure the extension (.BMP, .TIF, .EPS) you assign corresponds to the file format type you’ve selected. 5.
10. Print the calibration chart on your color printer. 11. Exit your image editing application. Note: To print images on more than one color printer, print the calibration chart on each printer you’ll use. If you plan to print the image on a service bureau’s color printer, have them print the calibration chart on their printer so you can create a calibration profile for it. b b Tip: When you label the printed charts to help you identify which printer produced them, don’t write on the chart itself.
You see the following screen: 4. In the File Name field, type the filename of the calibration file you want to create, such as COLOR1.CAL. Make sure you use the CAL extension. 5. In the Description field, type a short description of the printer for which you created the calibration chart, such as Custom.
Note: If a message appears indicating that the specified scan settings are incorrect, you need to reset the Destination options to their default settings. Click the Destination button to open the Destination dialog box; then select General for the Calibration setting, and 180 for both the Resolution settings. Save the settings by clicking Save; then choose Scan again. Always create Calibration profiles using these default settings. You can now use this calibration profile when you scan images.
If you created a custom calibration profile for your printer, type a unique name for the profile in the Destination Name field. Go to step 5. 5. From the Calibration pull-down menu, select the profile name you assigned when you created the profile. 6. Choose Save. 7. Choose OK. You see the EPSON TWAIN advanced screen. You can now preview or scan your image using the calibration profile for your color printer.
Chapter 3 Capturing Images From Within Applications When you scan an image from within an application using EPSON TWAIN, you follow these basic steps: 0 Access TWAIN from within your application’s File menu 0 Choose either the easy or advanced TWAIN screen cl Select the correct image type and destination settings cl Preview the image and select the scan area (advanced screen only) P Scan the image cl Close TWAIN and edit the image in your application.
Accessing EPSON TWAIN To access EPSON TWAIN, choose Acquire (or Place, or the appropriate command) from the File menu within your application. You may then have to select TWAIN or TWAIN32 from a submenu. When TWAIN opens, you see either the easy or advanced screen, depending on which was opened last. The easy screen allows you to select the type, destination, and document source (if available) of your image. When you scan with this screen, your entire image is captured and scanned.
Using the Easy Screen The following basic settings are available on the TWAIN easy screen: Cl Document source D Imagetype D Destination. You must select the appropriate option from each of these settings to successfully scan your image. selecting the Document Source If you have the optional Automatic Document Feeder (ADF) or the optional Transparency Unit installed on your scanner, you can select the option from the Document Source pull-down menu.
Selecting the Image Type To scan images with satisfactory results, you must use the correct image type option. You can select one of the following options from the Image Type pull-down menu: Color Photo 256 Colors Black & White Photo Color Halftone Color Drawing Black & White Halftone Line Art OCR If you haven’t modified these options by changing any of their settings, the image type you select uses the default settings listed in the Appendix.
If you haven’t modified these options by changing any of their settings, the destination you select uses the default settings listed in the Appendix. To add a new Destination option or modify any existing settings, see “Using the Advanced Screen.” To scan text, select OCR (for Optical Character Recognition) from both the Destination and Image Type pull-down menus. Leave the settings for these options at their defaults, listed in the Appendix.
You see the following screen: Image 3 Type Not all options on this screen are available with all scanners, Image Types, or Pixel Depth settings. The Image Type advanced options are described in the following table.
Image Type advanced options (continued) ing large areas of similar tones greens so green areas are w l When possible, let your image editing software perform halftoning. ‘* The Text Enhancement Technology option does not appear unless your scanner supports this feature.
The following table identifies the options available with each Pixel Depth setting. Since both the Draft and Best Quality settings are available with all the Pixel Depth settings, this option is not included in the matrix.
Adding and deleting Image Type options To modify an existing image type, select it from the Image Type pull-down menu and change the necessary settings. Choose Save and then choose OK. To add a new image type, select a predefined type that closely resembles the one you want to create. Then delete the existing name from the Image Type Name field and type in a new name. Change the other Image Type settings as necessary. Choose Save and then choose OK.
Modifying the Destination The Destination dialog box allows you to define different resolutions for each destination output device. You can also use it to modify, add, or delete a calibration profile for your output device. To modify the Destination, click the Destination button, You see the following dialog box: Destination so0 IfI 172 I*{ dpi Selecting resolution settings Use the Resolution pull-down menus to select resolutions that produce the best results for your image type and output device.
Optimum scanning resolutions Output device line art Grayscale Color Monochrome printer 300-600 80-x170 - Desktop or off ice color printer 300-720 150-240 150-240 Printing press or imagesetter 600-1200 150-350 150-350 The higher the resolution you select, the larger the resulting image file. For example, an 8.5 x 11 photograph scanned at 300 dpi can produce a 24MB file. The same photograph scanned at 72 dpi creates a file of only 1.36MB.
Selecting calibration profiles Use the Calibration pull-down menu to select a predefined calibration profile or create a custom one. TWAIN can then use the profile as it scans to create the best quality image. EPSON TWAIN provides many predefined printer calibration profiles, including those for the EPSON Stylus color printers, listed below.
To delete an existing Destination, select it from the Destination Name pull-down menu and choose Delete; then choose OK. Previewing and Adjusting the Image Once you have selected the Image Type and Destination settings, you can preview and adjust your image before you scan it. (To use the special effects features, see Chapter 4.
Adjusting the Preview Area Once you see a preview of the image on the screen, you can define the area you want to scan or select the entire image area. To define a specific area, position the mouse pointer at a comer of the area; the pointer changes to a +. Hold down the mouse button as you drag the pointer across the image. When you release the mouse button, a rectangle on the screen identifies the scan area.
You can select the Lock icon to keep specific values in either the Width field or the Height field. Click the Lock icon once to lock the value in place; the Lock icon shows a closed lock. Click it again to unlock the value. As you modify your selection area or other image settings, you see the file size of the image in the Size field. Note: Some applications convert the image to full 24-bit data, so the actual size of the image may be larger than the value displayed in Size.
If you choose Scan from the easy screen, TWAIN automatically selects the entire image and scans it. If you are scanning from the advanced screen and have not previewed the image or selected a preview area for it, be sure to click the Auto Locate icon before choosing Scan. Otherwise, the entire document table is scanned. When you close the TWAIN screen, you can further modify your image using the features of your image editing software.
Chapter 4 Using Special Effects The EPSON TWAIN advanced screen gives you many options for editing images before you scan them. If you have image editing software, you can achieve all of the special effects described in this chapter-and more-using that software.
To save the preview image so it reappears in the preview window when you next open the advanced screen, select the Save Preview Image and Settings option. If you have performed a screen calibration (as described in Chapter 2), you can enable it by selecting the Enable Screen Calibration option. Note: 2% ES-300C does not support calibration.
Q Sharpness adjusts the focus Q Threshold adjusts the point at which the gray values change to either black or white. This option is available only when the Pixel Depth setting is Black & White and the Halftone setting is None in the Image Type dialog box. When Threshold is available, the other image control settings are not available. Note: The ES-300C scanner does not support Contrast, Highlight, Shadow, Sharpness, and Threshold settings. Follow these steps to use the Image Controls: 1.
3. Adjust the settings until the image in the preview window looks the way you want it to look. See the following table for guidelines on changing these settings. Method Description Value fields Type in the value you want for the setting in the field, Slide bars Move the slide bar until the preview looks correct.
After you have previewed an image, choose the Gamma Correction icon, . You see the following dialog box: __ highlights - midtones - shadows Linear Adjust the gamma curve settings using the slide bar. You see the effects of the new settings in the preview window. If you choose the Comparison icon to the left of the graph, you see either three or five comparison views with different gamma settings. You can choose the comparison sample that most closely reflects what you want the image to look like.
Type the name you want to assign to the setting in the Gamma Correction Name field and choose Save. Then choose OK. Now the name for the new setting is available in the pull-down menu so you can select it whenever you want to use it. You can also delete an existing setting by selecting it from the Gamma Correction Name field and choosing Delete. Then choose OK to return to the Gamma Correction dialog box.
You can change these settings in the Color Adjustment dialog box, as described in this section: 0 Gray Balance 0 Saturation Cl Color Filter. You can reset any preview image you’ve modified using the Color Adjustment dialog box by choosing the Reset button just below the Color Adjustment icon. Setting the Gray Balance Neutral shades of gray are produced by mixing the three colors in the image in approximately equal proportions. Sometimes, however, the resulting gray shades are not truly neutral.
To remove color completely from an image, move the Saturation slide bar all the way to the left. Note: The saturation setting is ignored in 3-pass scanning. Using Color Filters Color filters can help eliminate color tinges (or an undesirable overall color tone) that exist in the original. You can also use filters to give your image a specific color effect. When you click any point in the Color Filter wheel radials, that color is increased in the image.
Using Automatic Features The TWAIN advanced screen offers two automatic features: 0 Auto Exposure, which automatically adjusts the exposure of an image and sets the Highlight and Shadow settings Cl Auto Locate, which locates and selects the target image from within the preview image. Note: When you scan using the easy screen, these automatic features are always in effect.
Chapter 5 Saving and Exporting Images You can always scan an image using your TWAIN-compliant image editing application. However, if your application is not TWAIN-compliant, you can use EPSON Scan! II to scan the image and export it in a format your application can open, as described in this chapter. Saving a Scanned Image before you export an image, you need to save it in its original EPSON Scan! II format. Otherwise, you will not be able to retrieve it again in EPSON Scan! II. Follow these steps: 1.
5. Choose the drive and directory where you want to save the image. 6. Type a filename for your image in the File Name field. Make sure to use the file extension .ORG. 7. Choose OK. The image is saved in the EPSON Scan! II file format. You can now open this file and export it with a different format, as described below. Exporting an Image EPSON Scan! II allows you to export an image in a file format your application software can use.
2. Choose the drive and directory where you want to save the image. 3. Type a filename for your image in the File Name field. 4. You can choose one of these formats from the File Format menu: DIB, TIFF5.0, TIFF6.O(JPEG), JPEG, and EPSF. (For a description of these file formats, see the Term Glossary.) Note: You can select TIFF6.0(JPEG) and JPEG formats only if you selected 16 Million Colors for the Pixel Depth setting in the Image Type dialog box when you scanned the image. 5. If you selected the TIFF6.
Follow these steps: 1. Start EPSON Scan! II, if necessary. 2. Choose Acquire and Export from the File menu. You see the TWAIN screen. (If you see the easy screen, click Advanced.) 3. Choose Scan. You see the following dialog box: I Rlrectorles: ciepeccan2 Rle &me: ccl I 0 epscm2 tl I M 4. Choose the directory and drive where you want to save the exported image. 5. Type a filename for your image in the File Name field. 6. You can choose one of these formats from the File Format menu: DIB, TIFF5.
7. If you selected the TIFF6.0(JPEG) or JPEG format, EPSON Scan! II allows you to choose the image quality. Since JPEG is a Lossy compression scheme, selecting higher quality gives you less compression. To choose the image quality, move the Quality slide bar to the desired setting. 8. Choose OK. The image is scanned and exported in the selected file format. You can now import this file into your application software; see your software manual for instructions.
Chapter 6 Troubleshooting If you have problems using the EPSON Scanning Utilities, or with the quality of your printed or scanned images, check the two sections in this chapter for possible solutions. Problems Using the EPSON Scanning Utilities When you select a TWAIN data source, EPSON Scanners is not listed. Either the EPSON Scanning Utilities were not installed or they were not installed correctly. Reinstall the EPSON Scanning Utilities; see Chapter 1 for instructions.
You may have selected the wrong port number or SCSI ID during setup. Check the settings for your scanner and any other SCSI devices you may have. Then reinstall the EPSON Scanning Utilities. You may have changed the interface from parallel to SCSI or from SCSI to parallel without reinstalling the EPSON Scanning Utilities. Reinstall the Utilities for the correct interface.
Your scanned image may be too big. Reset your system and reduce the size of the scanned image. The EPSON Scanning Utilities do not start. Make sure you are using a system with the minimum requirements for the EPSON Scanning Utilities. See the Introduction in this manual. Check that the system requirements are correct for your application software and that your software supports your scanner model. Be sure that you have correctly installed and set up your application software.
After choosing the Preview icon, the image does not appear in the preview window. Press Enter or click on the TWAIN preview window. The scan is not the full width you selected in the preview area. The EPSON ES-300C and ES-600C scanners restrict the scan width to 4096 pixels at high resolutions. Choose a lower resolution for a wider scan. After scanning and opening several scanned images, your application software fails and your scanned image is lost.
The Document Source setting is grayed out in the EPSON TWAIN screen. This is normal. You must first connect an optional Automatic Document Feeder or a Transparency Unit to the scanner for any Document Source option other than Flatbed. The Preview button is grayed out when the Automatic Document Feeder is selected under Document Source.
The default settings for Image Type and Destination don’t meet your specific scanning requirements. You can define your own settings; see Chapter 3 of this manual. The Halftone setting in the Image Type dialog box is grayed out. Halftone and dither settings on most EPSON scanners are only available when the Pixel Depth setting is set to Black & White or 8 Colors (1 or 2 bits per pixel per color). The application software displays an error message, freezes, or fails after scanning.
After scanning with an image editing application, the scanned image disappears. Make sure you close the TWAIN screen before switching to your application software. (Do not use the Windows Minimize button.) The rows in the screen calibration dialog box never seem to match closely enough. Try adjusting your monitor’s brightness and contrast settings. The TWAIN screen changed its color settings after a preview scan. Increase the number of colors or decrease the resolution your monitor displays using Windows 3.
After starting a multipage scan using the Automatic Document Feeder, the image editing application freezes, displays an error message, or fails. Reset the system and reduce the number of pages you are scanning with the Automatic Document Feeder. After closing the EPSON TWAIN screen, a partial image of the screen appears over the scanned image. Use the Up or Down arrow or the mouse to scroll the application’s frame and clear the partial image. Using CPI Image-In® Color Professional 3.
Using Adobe Photoshop 3.0.4 with Windows 95, you cannot select a 32-bit TWAIN data source. You need to obtain patch files from Adobe Photoshop to allow the program to use the 32-bit TWAIN data source. See the instructions at the end of Chapter 1. Problems With Image Quality The entire image is distorted or blurred. Make sure that the document is placed flat against the document table. You may have moved the document during scanning. Check the position of the document.
Color is patchy or distorted at the edges of the document. 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 having outside light interfere. If part of the original is outside the document table, the edge may not be in contact with the document table and may be discolored. Change the position of the original. The image is faint or out of focus. Make sure the document is placed flat on the document table.
The image does not look the same as the original. Make sure you have performed the calibration procedures and selected the correct printer profile; see Chapter 2 for more information. Try different combinations of scanner settings. Check that your software is correctly installed. If you are importing an image file into your application software, see if the file format is acceptable for your software. Also check that the settings of your application and your image match. See your application software manual.
Make sure you have correctly performed the calibration process in EPSON Scan! II. Recalibrate and try again. Check your scanner settings-such as Pixel Depth, Gamma Correction, and Color Adjustment-or try a different combination of these settings. The printed color seems different from that of the originals. Check that you have correctly performed the printer calibration process in EPSON Scan! II using the correct printer profile. Recalibrate and try again.
Images cannot be scanned at all or only a few dots appear in the scanned image. Try different EPSON TWAIN settings. Be aware that some settings disable others for a particular effect. Also, depending on your scanner, some features may not be available. Set the Brightness, Highlight, or Gamma Correction to darker settings and scan the image again.
The image appears upside down and truncated in your application software after scanning. Before you scan the image, reduce its file size to less than 1MB by adjusting the settings on the TWAIN advanced screen. When you select 256 Color as a Pixel Depth setting, the scanned image does not match the previewed image. Select Color Photo as the Image Type and try scanning again. Select 16 Million Colors for Pixel Depth and try scanning again. The image looks corrupted. Check your printer driver settings.
