Good day
I have a scanner - Canon LiDE 20 , it worked for a month perfectly , but since yesterday, whatever i try to do it writes the following error message:
Release the lock switch, disconnect the USB cable and reconnect, then restart toolbox
Scanner driver will be closed
Unable to locate TWAIN source

Is there anything to do , except going to the distributor . Why that error appears, cause the lock switch is on released mode

Thanks in advance

iirc, this scanner is powered through the USB cable instead of an external power supply. Is that correct?

A number of months ago I had a client who suddenly developed a scanner problem on one of these (can't remember if it was a LiDE20 or 30 though). The exact error message escapes me, but it turned out to be that the scanner somehow ended up plugged into a standard USB cable instead of Canon's specific scanner cable (I think he was trying to use a longer cable). Using the correct cable ended up taking care of the problem. Beats me as to why.

Otherwise I'd probably give Canon a buzz for some help. Life will be easier if you do the usual troubleshooting nonsense first ... e.g. undo whatever changes you made since yesterday (if any); see if it works on a clean system; etc.
