77 chapter 7 Troubleshooting Top Page Glossary Contents Index Pre-Scan Checklist Perform the checks on this short list before you begin troubleshooting specific problems. •Make sure that the ScanGear CS-U software was installed successfully. •Confirm that the cables between your computer and scanner are connected securely. •Before scanning or previewing, check that the data source has been selected. If your scanner does not appear as an option when you select a TWAIN source to scan from your imaging software, you have to install ScanGear CS-U again. (p.12)
78 chapter 7 Troubleshooting Top Page Glossary Contents Index How to Avoid Problems Here is some general advice on avoiding problems in your scanning jobs: •Start with the best possible original image to scan. •Select only the part of the image you want to scan. Preview the image and select it with the Crop and Auto Crop buttons. Not only does a more precise selection save file space, but your image quality will be much higher. •Check the output file size before beginning the scan. Make sure you have enough room if you are scanning files that require a large amount of disk space. •Match your Color Mode to the output purpose. If you are scanning text, use the Text Enhanced mode. If you are scanning line art, use the Black and White setting, and so on. •Match your scan resolution to the type of file you need. If you are scanning images for use as .GIF or .JPG files on the Web, you do not have to scan at 600 dpi. Although it is recommended that you scan at a higher resolution than you need for high-quality color images, you should balance that factor against your planned use for the image. •Take advantage of the Tone sheet features to enhance your images. (p.40) •Try to use TrueColor mode on your monitor so you can view your preview image as accurately as possible.

80 chapter 7 Troubleshooting Top Page Glossary Contents Index Troubleshooting Checklist The scanner diagnostics test fails. Problem:The Scanner Diagnostics test started with the Test Scanner button on the Scanner sheet, returns a Test Failed message. Cause:The scanning unit may not be in its home position. Solution:Close the ScanGear CS-U window if it is open. Try turning the scanner off and back on again by unplugging and plugging in the USB cable. Then restart your computer. Colors not what you expect. Problem:The colors in the preview image appear different from the colors in the original image. Cause:The scanned colors need to be adjusted. Solution:Make sure the Auto Tone button is selected. If further adjustments are necessary, use the Tone sheet buttons. The preview image of a photograph appears blurred but the scanned image of the same photograph appears sharp. Problem:When zooming in on a photograph in the Preview Area, the enlarged image appears blurred. Cause:The preview scan uses a lower resolution than the final scan. If you zoom in on a preview image so it is enlarged, the image will not maintain its resolution in the same way as the final scanned image. Solution:Select a magnified area and preview the image again. The scan should display a sharper image.
