Unknown capability with different scanners

[mmImc]

When trying to run the method TwainShowSetupDialogSource with different scanners, it will fail depending on the scanner. One scanner it fails with is an Epson V700. We have verified we are using the latest drivers. The following is the contents of the twain log while running this method:

Code: Select all

#GdTwain Log Start. Version: 630

RC:   TWRC_FAILURE
CC:   TWCC_BADVALUE

Would you be able to advise how to correct this?

This is also occurring with a Epson Perfection 3170 Photo scanner.

Hi,

Your 2 scanners seems to doesn't support this feature. unfortunately, I can't do anything. It is an issue related to the driver itself.

Kind regards,
