I have a visioneer7100 that the scanner itself will not move much, ileave it turned on all the time and dont know if it burned out the moter or why its not working but if thats the case should i have unpluged it or what. and also what scanner would you recommend to use. I dont use it much but is nice to have when i need it.

Scanners need downtime, just like any human being. It sounds like either -
1) its pack up its bags and gone AWOL,
2) the transformer / PSU has gone
3) and / or needs resetting via been unplugged and left to settle for a while.

The best course of action is to leave it unplugged for a while, let it have a vacaition. Check the transformer to see if its hot. If its hot there's power flowing, if its too hot it could potentially be entering a danger zone, where the transform could spontainious combust*.

All in all, you could just go an buy a new scanner, as the technology is constantly evolving and moving on. You can probably get a better scanner for the same amount of money you paid for you old one, if not less
