All actions must be performed in the HP PrecisionScan Pro software, because you must scan slides, negatives, and other transparent items using this software. See also "Resolving issues with the XPA" on page 95. You might have used the Zoom In command, which only changes the view on the screen. Use the Resize command to change the size of the final scanned image. See "Resizing (output dimensions)" on page 38. The software might be setting exposure for the entire area instead of one slide or negative. Create a selection area around the slide or negative you want to use to ensure it is exposed correctly.

Check the original slide or negative for damage. The calibration area at the top of the large template might be scratched or blemished. If there are scratches or blemishes, turn the template over and scan again to see if the streak moves to the other side of the scan. If the streaks move, then the template needs to be replaced. One of the two bulbs in the XPA might be broken or not working. With the XPA connected to the scanner, hold the XPA up and look for even illumination on both sides of the XPA. If a bulb is broken, service is required.
