    I have the the same problem as stated above. I can scan after a dozen or so tries sometimes it scans several times in a row with no trouble and then starts again.

    I have the same problem with a 5800 model scanner that I recently bought at an auction for $15.00 stating that it is locked and to unlock the device. Only problem is, is that there is NO switch ANYWHERE to lock or unlock the scanner.
    I also had problems with color and streaky lines thru the scan, when it does work.
    I usually can get the scanner to work by tipping it on end and gently tapping it. It appears to be hanging up on something.
    I also took it apart and thoroughly cleaned it and to correct the color and streaks, I left the cover off and kept hitting the preview button and gently tapping one side or the other of the scanner until it showed a totally black scan.
    I also have a 5820 model that states that is is locked occasionally.
    On that one I usually just jiggle the cords to get it working again.

    To solve the problem of turning off the scanner when I don't need it, I just use an on/off switch plug between the scanner and my power strip....or you can just unplug it when not in use.

    I really like each one and think that they work really well.......

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...

Scanner will not scan, says it is in locked position.


The locking tab protects the scanner's scan head by holding it securely in position. Lock the scanner when transporting it from one location to another, but always remember to unlock it before scanning. The scanner will not scan when locked

Looking the bottom, upside-down, with the back/bottom (power cord side) down. The lock is in the upper right corner. It is a slide style tab. Move up to unlock the bed.
Look on the users installation guide page 7 for illustration.
Need the guide, just ask.

'Unlock the hardware lock' message


Does the scanning carriage move at all when the scanner is starting up? If not, then it might have stuck and needs to be moved back and forth a couple of times manually to loosen in, with the power not applied of course, and for that you would have to remove the glass most probably.
Also observe if the belt that moves it is properly attached to the carriage, placed over the motor gear and the support gear at the other end.
Of course the motor itself might have failed, or it's control electronics.

How do I scan slides with the Visioneer 8920?


In the Twain window at the top is a dropdown menu where you can select 35mm slides. That gives you two choices of resolution at 1200 or at 2700 dpi, plus a custom setting option.

The scan motor is straining against somethinmg - so re do the lock/unlock routine and carefully examing the machine and the manual - usually in PDF on the software disk.

I have had this very problem with 2 of these scanners (8920) and finally figured out what happens is that the cheap chinese power supply loses power over time and then finally gives out. Before it fully gives out it doesn't have enough power to scan properly but will still turn the scanner on. Symptoms range from terrible scans with noise to the dreaded "scanner is locked" error. I got a new power supply from radioshack - 12 VDC at 1.5A (1500 MA) and it works like brand new! Make sure the power supply can deliver the full 1.5 A of the original! This is very important.

Get another scanner. Check whether the lock has not been enabled at the bottom of the scanner. This has happened with me as well and a known Visioneer problem.
