I also have the same problem. I cant anything under the scanner that unlocks it.

I also have same problem. Could someone please help?

Ivan

I cannot find the tab on the bottom, that you move to unlock.

Does anyone else have the tab on the bottom of the 4800?

this is seriously bugging me.

i found a site online that has the answer to our problems but we are looking at paying a monthly subscription just to find out, which i refuse to do.

i have had this scanner for years but have left it unplugged for a good 3 years atleast, it worked fine originally but now its doing the whole ooo unlock me thing and im n the same boat where there is no lock.

i cant find any info out on the visioneer site, although thatis a very helpful site.

well im struggling with this also, i cannot find a tab anywheres and not having used the scanner for years i cant think where or what it is, when i first installed it it worked fine.

I also have the same scanner as all of you, but have never had this problem before, have you tried reinstalling the scanner. will it work on other computers?

I have the say problem as you guys..... Ive try the reinstall game with no joy and had no luck with updating the driver, so if there is anyone out there that could help us people with our out dated scanners we would be most greatfull.

Hi guys don't know wether this will still help you but I had the same problem & just managed to scan again!
Firstly I reset the Twain device (using twain_reset.exe, found by searching on google & viewing the cached page) Then In paperport I did File>acquire & then the scanner tried but suggested I may be scanning in another application. I realised this was because the scanner arm was'nt moving so in a very technical way I hit the scanner a few slaps to the front & hey presto I'm back in business!
Hope thats of use to someone!
