If you can't scan at all, please ensure that you can scan from other programs. If not, then the problem is with the scanner itself and not Rapid Resizer.

If you don't have version 3.5 (you can check by choosing About from its Help menu), you can install it here. If it requests a new key, you can also get one on that webpage.

When scanning from Rapid Resizer, it suggests a few things to try to fix problems. Try those first.

At worst, you can scan from Windows' built-in scanning software:

  1. Click on the Windows Start button in the lower-left corner of your screen or keyboard.
  2. Type scan to search for your scanning program. Click on its name to start it.
    • If you're using the Windows Fax and Scan program:
      1. Click on the Scan button in the panel on the left, if not already chosen.
      2. Click on the New Scan button in the toolbar.
      3. Click on the Scan button. Setting the DPI to 300 is recommended.
      4. Click on the Save As button in the toolbar.
    • If you're instead using the program that came with your scanner, follow its instructions. Then save the scan to a file on your computer. Try to save to your Desktop so you can easily find the file later.
  3. Open your scan in Rapid Resizer. Your file may be in your Scanned Documents, Documents, or Desktop folders.
