Is the TPU plugged in? When the scanner works for "normal" scanning, it should also work in TPU mode. THat the scanner thinks that the TPU is not active can have a number of reasons: - TPU is not plugged in - The TPU is covered by the white background that is required for scanning off the glass - The TPU is broken The name that the scanner reports is OK. The GT-xxxx is an internal name that is usually (that is with e.g. Windows drivers) not exposed. Because I don't have two versions of the backend (Japanese, and rest of the world), I don't distinguish between Perfection-xxxx and GT-xxxx. GT-9700 is the internal name for Perfection 2540, you got what you paid for.
