Hi .... This Scan jet was from my office - I have never worked with it ... My assistant used to scan all our pictures with this scanner everyday  .... I was i advertising business, now retired - Anyways ...  I don't know how to work with it .... I think it needs a software program .... I hope you know how to work with it ...  It was working when I closed my office 4 months ago ... it is 18 x 12 x 1.5" ...
