On paper at least it has all of the right credentials. First, it's pretty speedy. According to the spec sheet it will scan documents at speeds of up to 23 A4 pages per minute (ppm), at 200dpi in black and white and 10ppm at 200dpi in colour. Moreover, it will scan both sides of your pages simultaneously, giving a total potential throughput of 46 sides per minute. And there's no reason to doubt these figures. In tests the scanner was faster than the quoted speeds, running through 34 A4 black and white pages in one minute one second. Colour pages were delivered at the same speed, and at 600dpi in colour, the 34 pages took three minutes 56 seconds to acquire.
