Hi, i am using dynamic web twain 6.3.1.0 on IE9 and when trying to scan with scanner
fi_6230 on some pcs, not all pcs, i am getting following error:

Code:
Twain driver error: Communication failed. Make sure that the power to the cable is firmly connected and the scanner is not used by another application. Code:D542019


i tried removing cables and plugging them again, restarting pc, uninstall and install scanner driver again with no luck, strange thing is that the same scanner is working fine with no issues on another pc.

any advises ?

Hi mahmoud.saleh,

Welcome to the Dynamsoft TWAIN Forum.

Regarding the issue you reported, can you update your driver to the latest version and see if it works?

If you are still having this issue after updating the scanner driver, please use Twacker and see you can do the scanning in this software. How to use TWACKER to check my scanner? >>

Note: TWACKER is a TWAIN application developed by The TWAIN Working Group, and it allows you to exercise features of a TWAIN driver and to see whether the driver of your device is working fine or not.

Thanks,
