Increase the shadows value of the scanned image using the lighten/darken
image adjustment tool in the HP Scanning software to reduce the banding
effect. "

Is it really that bad? My current scanner doesn't exhibit any sort of design defects; it's just a bit slow. The problem with the HP scanner sounds like it would almost be worse, especially if it happens
even if the item being scanned is properly flat against the glass. I wonder what the cause of it is? You don't suppose that they are using an *interlaced* webcam-style CMOS imaging chip for scanning purposes, do you? Cost-wise, that would be brilliant. Design-wise, that would be horrible. (I was wondering why HP would even describe the problem as an "even-odd" problem - interlacing is the only thing that comes to my mind.)
I actually didn't get to the store before it was going to close, now I'm not sure if I want to pick one up or not. Hopefully someone else who owns one will chime in too. The thing that I don't get is, the whole
point of an increased bit-depth for scanning, is increased clarity and dynamic-range at the low-end - eg. the darker portions of the image. Yet that seems to be where HP is suggesting that the problem could occur. If it's cheap, flat, USB 2.0 high-speed, and scans documents (high-contrast images) well, would it still be worth it to get one? (Edit: Decided not to at this point, I'm "picky" about my hardware.)
