The two key differences between the P570 and its smaller sibling are that it can't scan strips of film or slides, but it can scan to a larger size, at a maximum 5 by 7 inches instead of 4 by 6. Beyond that it's basically the same scanner with all the same features.
Setup and Scanning
The P570 measures just 1.8 by 7.6 by 3.3 inches (HWD), which makes it bigger than the P460, but by only a little. The 5-inch wide manual feed slot in the front feeds straight through to.
An exit in the back, where you'll also find the power connector and a mini-USB connector. Also on the front is a memory-card slot. Setup is trivial. Simply plug in the supplied 2GB memory card, and connect the power cable.
To scan, you turn the scanner on, put a photo in one of the supplied protective sleeves, and insert the photo into the front input slot. The scanner will detect it, grab it, feed it, and scan the photo to a JPG file. The only setting you can control is resolution, with a button that switches between 300 pixels per inch (ppi) and 600 ppi.
