How to fix difficulty communicating with the scanner or TWAIN errors


You are here:

If you have a ScanSoft product and it is having a problem communicating with your scanner. If you receive an error message during scanning, very first step that should be taken is to make sure that the scanner is properly connected and turned on, then determine whether the problem occurs with all scanning software or only with ScanSoft software.

Exit all applications

Shut down your computer properly, then restart Windows

Use your scanner with a non-ScanSoft scanning application

If you still experience scanner errors, please contact your scanner’s manufacturer for support

If you only have scanning errors when you are attempting to use a ScanSoft product, use the following procedure to display the scanner’s TWAIN driver software before a scan.

Close the ScanSoft product and exit all running applications

Click Start

Click Settings

Click Control Panel

Select the Scan Manager to display a list of scanners that the ScanSoft product recognizes. This list usually contains only one or two scanners

Right-click your scanner and select “Properties” to display a multi-tabbed Properties dialog box

Click the TWAIN Scanner Settings tab

Set the property Show TWAIN Settings Before Scan to Yes

Close the Scan Manager and the Windows Control Panel

Open the ScanSoft product and attempt another scan. This time, the scanner’s TWAIN driver will load and enable you to change its internal settings before scanning

If you still get errors, go back into the Scan Manager and check the property for the Current TWAIN Data Source. If other TWAIN data sources appear in the “Available Data Sources” list

Try selecting and experimenting with another data source.
