Don't by this scanner if you expect anything close to 4800 dpi.I bought this scanner with the intention to scan my slides.I was not able to get the resolution I expected from a 4800 dpi scanners.The result was only marginally better than the result I gotby projecting the slides and taking images using my 3 MPix digicam.By using the "slanted edge" method I measured a resolutionthat rather looked like a 1200 dpi scanner.Also when using the slide adapter the result become evenworse since the slides become more out of focus.Got no help from HP support. The reaction to my measurementswas basically "that's the way it is"Also: The software user interface is kludgy and hard to work with.This is not what I expected from HP, my previous experience ofHP-products is quite good.
