If the pre-scan is fast, scanning is much slower but good quality. I have not yet tested the photo mode. It is unfortunate that the software implemented at the time of installation not possible to direct output to a printer. It is systematically creating a picture or Pdf file is performed. What makes him lose a star to my rating. You must install a rudimentary utility (provided on the CD) that does not display a preview scan before printing. This acts as a simple copier. The cover is not secured to the base allows you to place a thick original (book) even opened. Digitization in the binding of the book is slightly deteriorated and remains very readable.
