The Scan dialog box which is ideal for quick and simple scans and the TWAIN dialog box which offers more control over the output. [. . . ] · Batch Scan Button Clicking this button allows you to create multiple scan areas using different scan settings on the image shown in the Preview Window. · Scan After determining the exact image area you wish to scan and selecting your desired scan settings, click the Scan button to perform the scan. When scanning is complete, the image will be displayed on the main screen of the host software behind the TWAIN dialog box. · Help Provides on-line help for the scanner and software functions. · Language Icon Selects the language you would like to view the TWAIN interface in. · Exit Icon Exits the program. 15 The Image Buttons Setting The Image Setting buttons allow you to create your own convenient scan settings. Saving image settings allows you to use the same settings again and again without resetting the image options. Art Print Choose Art Print when scanning images from very high quality art prints that show only very fine dots. Output Scaling Output scaling allows you to enlarge/shrink the size of the final output image. Adjust the scaling by using the slide bar or typing the desired setting in the Output Scaling box. For example, setting the Output Scaling to 200% will double the amount of pixels contained in the image. Width and Height The Width and Height values show the dimensions of the image area inside the Crop Frame. Image Size Image Size displays the amount of disk space needed to display or save the image outlined by the Crop Frame in the Preview window. The Image Size information is automatically updated anytime you change any of the scan settings or resize the Crop Frame. Color Match This is an effective tool for ensuring that the colors captured by the scanner more accurately reflect the actual colors of the original image. Without color matching the scanner captures a wider range of colors but these colors may not accurately match the true colors of the original image, making the scan appear different from the original. Color Balance This tool balances the lightest and darkest areas of an image so that they are equally distributed. Without Color Balance With Color Balance 19 The Enhance Tab The Enhance tab contains preprocessing controls that can be applied to the image before making the final scan. The Enhance tab contains two picture thumbnails (Original and Sample) of the preview image, several control settings, and a histogram of the image. Alterations made to the enhanc settings appear in the sample thumbnail. The image that appears in the thumbnails will automatically be replaced with the Preview image. If you wish to see the effects of your changes in the Preview Window, click on the Preview button. Channel Selector Channel refers to the red, green, and blue colors that make up a color image. You can choose to change the channels individually or choose Master to change all channels equally and simultaneously. Histogram The Histogram graph shows the distribution of brightness levels in an image. Using the control settings (Brightness, Contrast, Gamma) you can selectively adjust the brightness levels in the shadows, midtones and the highlights of the image. [. . . ] The scanner will begin to scan the batch jobs one after the other. Batch Scan Status Batch Scan Completed: The medium green light at the top of the image means that the scanner has completed the batch job. Batch Scan in Progress: The bright green light at the top of the image means that the scanner is currently scanning the batch job. Batch Scan Waiting: The dark green light at the top of the image means that this particular batch job is waiting to be scanned. 26 Appendices Appendix A: Scanning Tips The following tables provide helpful information you can use when setting the scan mode and/or resolution. Recommended scanning resolutions for various output devices are listed as follows: Space requirements for different scan modes: 27 Appendix B: Troubleshooting Notes: · It is not possible to print and scan at the same time.
