When you scan a book and the program reads IO Exception. It means either your SD card is defective or you did not download the database properly.

To troubleshoot, please follow the steps below:

  1. If you follow our Multiple SD card recommendation, try your other card to see if that fixes the problem.
  2. If you do not have a backup SD card, find another SD card to download the database onto. Make sure you set up your SD card here.
  3. If there is no IO Exception on your new card and you can scan items properly, then your old card is defective.
  4. If there is still an IO Exception, then contact us so you can try with a different PDA.
