Unlock scanner hardware?
I have the same scanner, which has now died due to electrical problems. This was the most posted issue people had with this model of scanner. The problem had come from the issue that the software was never truely adapted for the model. The Visioneer 5800 scanner had a hardware lock on the bottom. When they put out the (advanced) model 5820, the lock on the bottom was seen as pointless, so it was removed, but the software was NEVER adapted for it, except for the original Win98 version. Any version since, has the flaw of requesting the hardware lock being removed.
The only way I have found that actually gets around it is this:
You have to remove the screw(s) that hold the scanner body to the base, then either put them away in a forgettable box somewhere, or do as I eventually did... toss them in the round file.
Now, are you ready for this?.... When the scanner asks the question about the hardware lock, you have to gently pull out on the front lip of the scanner, and lift the main body from the base.
Now GENTLY, so as not to destroy anything inside.... You must pull the advance belt so that the scannung bar moves foreward about an inch. NOW, close it up carefully.
Now when you ask for a scan, it should work.... I was quite amazed when I first read this solution, but it worked for me for many years of scanning with this machine, and a very good scanner it was, too!
Now, if you don't want to do this over and over, and over again... here is the secret that kept me sane (except for when the power went out, and I had to do it again occasionally.)
When you scan, use the Passport software, and pull up the twain to scan.... go about your business as usual, BUT!!!, when you finish scanning, close down the scan preview popup FIRST. Then close down the Passport software. IF YOU DO NOT CLOSE THE SCAN WINDOW FIRST, YOU WILL HAVE TO LIFT THE SCANNER LID AGAIN and over, and over, etc.
Now, print this before you start unscrewing anything, as it is rather involved.
Good Luck! BScott
