TWAIN and ImageEN dont detect my scanner

Question

I'm writing an application in delphi 2010. I want to scan image in this application. But both TWAIN and ImageEN cant detect my scanner. But windows detects it. How can I fix it?

Answer 1

You may take a look at their release notes .

IMAGEEN Version 3.1.2 doesn't work with WIA driver. WIA is supported in the latest version - v4.1.0.

I have the following two suggestions:

1. Install a TWAIN driver to work with your current version. As far as I know, most scanners come with both TWAIN and WIA drivers (and ISIS etc.). Google your scanner model! I believe you can find a twain driver.

2. Upgrade to their latest version which supports WIA.

Answer 2

TWAIN will usually list a WIA source in the DSM, so even though the scanner is present in the Windows device manager, if it doesn't show up in the TWAIN DSM, either something else has gone wrong, or that scanner simply doesn't have a TWAIN or WIA driver. There are some proprietary scanners that don't have TWAIN or WIA drivers, like the Fujitsu ScanSnap line.
