Are you doing a native transfer? If so, the TWAIN spec says a DS can transfer a partial image for a native transfer if it’s in unable to allocate the entire image. See the section “Options for Transferring Data” in chapter 4. I don’t have an AVision scanner so it’s just a guess but changing the resolution does change the memory requirements.
It sounds like that machine has ample memory since other scanners work. For whatever reason, the AVision DS is not able (or willing) to allocate RAM for the transfer. You might have better luck using a memory or file transfer.
If the AVision can transfer an entire high resolution image on a different PC, look at the differences between these two PC’s. For instance, do they have the same version of the AVision driver?
