I am trying to scan 30 slides but only 25 scan. How can I scan all 30 slides at one time?

• Do the following:
  1. Make sure the transparency guide is installed: Place the transparency guide at the back edge of the document glass, so that its alignment pins fit into the holes as shown.
     
  2. Place the first slide holder on the scanner glass. Align the slide holder with the notch on the transparency guide, as shown below.
     
  3. Place the second slide holder on the scanner glass, adjacent to the first.
  4. Then try scanning again. See Using the Transparency Unit to Scan for details.
