It is the first time to use this scanner, did not think the original scanner is really so good, you are really powerful, I also did not think this is scanner or so for it, this time I also really see this is scanner very good, but also is a lot of people are feeling after using this scanner, for our work is a great help, and especially the scanner is very easy to use, and is particularly convenient, so this time I would also very much hope that has been able to use this scanner is especially good, the feeling is the company to buy this scanner really is too much of a buy.
