Re: 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

Re: Unlock scanner hardware?

I have no solution. The only thing I can say is that most of this information is gobbledygook to some of us newbies. I don't know what you mean by "pull up the twain to scan", I had to download a driver and software (PaperPort), have no instructions to follow, have figured it all out myself, except for unlocking the scanner. Nothing works. I can't even remove the top because I can't get the screws loosened. An explanation for idiots would be nice. Thank you, Wanda

Why do I get an error message: Internal error occurred. Scan driver will be closed. Code:5,202,52?

Look at the bottom of the scanner and there should be a lock/unlock slider. Unlock it and see what happens.
If it is already unlocked then the drive/stepper motor or belt is bad.

My 5800 keeps telling me to unlock it when I click scan, but I can't find the lock anywhere.

The 5800 scanner does not have a physical lock switch. DO NOT attempt to open the scanner and unlock the hardware. This could be either a hardware failure or software
Toggle the lock switch on the scanner leaving the switch in the unlocked (open padlock) position.
Ensure you are using the correct power supply for your scanner. If you are using a power supply that has the incorrect DC output, you will get a scanner locked error message. This flatbed scanners has I believe 100-120V AC input and 12V DC output.

Plug the power directly to the wall, not a UPS battery back-up, power strip or surge protector. Power fluctuations from a UPS battery back-up, power strip or surge protector may be causing this error. If all this fails try reinstalling the scanner driver

Will not scan. Scanner hardware is unlockedl

I don't know what your electronics skill level is, but if you feel up to it, try taking the scanner apart and using a jumper wire to close the circuit so that the scanner is permanently unlocked. At least on a scanner this old you do not need to worry about voiding any warranty...

Scanned image comes out all black

The scanner has a locking device for transport. If it has inadvertently gotten flipped it will cause this issue. Look for the little green or blue tab labeled "Lock" "Unlock" making sure it is unlocked.

Most scanners shipped have a lock on them to prevent the top from opening up and damaging the glass. This is a screw type mabey other but a penny fits in mine. This may not be the case for you but look in your manual to find the unlock device.
This will also in some scanners prevent the stepper motor from moving in transit . The stepper motor is the device thats makes the bar slide up and down to scan the page.
Hope this helped some.
