Bad Handle error when using a Kodak i600 TWAIN driver on a 64-bit Windows 7 OS with VRS Multicore Processing enabled

Question / Problem:

Errors occur intermittently when using a Kodak i600 TWAIN driver on a 64-bit Windows 7 OS with VRS Multicore Processing turned on.

The VRS Test Application (VCDemo) will encounter the error:

Error 20160 - Bad handle or unable to access data with handle.

The Kofax Capture Scan module produces the following error:

An error occurred while scanning or importing - Bad identification parameter supplied.

Answer / Solution:

The errors may be eliminated by:

• Turning off the VRS Multicore Processing
• Using the certified “Kodak i600 Series (Software)" ISIS driver in the Scanner Configuration Utility.
• Using Windows 7 32-bit OS.

This behavior has been documented in SPR 88869.

The Kodak i600 series TWAIN driver is not certified for use with Kofax VRS 5.x.  While it is considered a certified scan source in Kofax VRS 4.5, the preferred scan source for this scanner is the certified ISIS driver.
