Does anyone have a recommendation for a good portable scanner that works well with the iPad? I know you can just use the camera for a number of apps. I've done that but it takes a lot of time to line up the camera just so and work the edges correctly. Still you don't end up with a professional looking scan. I've tried the Ion Air Copy, which at it's tech specs should work perfectly. It creates it's own wifi to connect with the iPad, iPhone or PC and transfers the image that way. However, I haven't been able to get one that works dependably. My first one worked 25% of the time and then developed white lines on the scans that couldn't be cleaned off the lens. I just got a replacement and it doesn't work consistently with the wifi either. So I'm sending it back. I don't have to have wifi but would be happy with a scanner that can just transfer via the camera connector. Does anyone have a portable scanner that can use the camera connector to transfer the images? Thanks for your help.
