I have had nothing but problems trying to use this scanner. The software constantly locks up. A message is then displayed stating that the scanner cannot be found. The light stays on. There is a patch on the HP site. It however, did not correct the problem. When and if you can get it to work, it does a fantastic job. Very good resolution and accurate colors. Sometimes you can remove the software and then reload it to get the scanner to work. If you are lucky and it starts you had better do all your scanning as it may not work once you have gone to a different application and try again to use it. I am very disappointed with HP's customer support. If the product is over 90 days old, it costs an arm and leg to talk with anyone. I plan to replace it with an Epson 1200.
