Incorrect colors print, or the image is too light or dark ● The software might be setting the exposure for the entire area instead of for one slide or negative. Select and drag the handles around the selection area until you see the image area you want to scan. ● If there is unused space in the HP Scanjet G4010 negative strip holder or slide holder, push the negatives or slides all the way to the bottom of the holder and slide the TMA cover in to fill in the empty space. ● If you are scanning fewer than the maximum number of slides or negatives with the HP Scanjet G4050 TMA, cover the empty spaces with the light shield provided. This ensures that no extra light leaks into the scan. ● The settings for transparent materials are reversed. Make sure that you have selected Scan positives, such as 35 mm slides, using the TMA for slides, or Scan negatives using the Transparent Materials Adapter (TMA) for negatives. Dots or streaks appear in the scanned image ● Check the original slide or negative for damage or debris. ● Clean the TMA with a dry, soft cloth. If necessary, lightly spray the cloth with a mild glass cleaner. Allow the glass to dry thoroughly before scanning another image. 22 HP Scanjet G4000 series
