Hello,

This error message comes from your TWAIN driver. You should check that it is correctly installed and up to date, try with latest TWAIN API etc... Here all details: viewtopic.php?t=1486

If the problem persists this can be a hardware failure, the device manufacturer should be able to offer some help regarding the signification of the error code.

I hope this helps!

With best regards,

Loïc
