Question : Problem: Unlock Scanner

My onetouch visioneer 5800 scanner will not scan.  Error keep popping up - unlock scanner - lock on the bottom of scanner.  There is no lock on the bottom of the scanner.

Answer : Problem: Unlock Scanner

Ensure you are using the power supply that was provided with the scanner. The label should be Bestec or HYI 100-120V AC input, and 12V DC Output, plugged directly into a wall outlet, not a power strip. The power through the strip may be fluctuating and causing the problem.
 
Verify you are using the minimum memory required to run the scanner: minimum requirements include 64MB of Ram.
 
Download and install the driver provided on the 5800 USB support website.
