unidirectional vs bidirectional flatbed scanners
Why does the scanner head needs to return to it's start position after each scan? It wouldn't be faster if it had 2 start positions at the edges or just leave the head in the middle after each scan? I think bidirectional scanning would be better for the lifespan of the arm motor too...
