How to handle "No page in scanner, add page to scanner?

[markgraybill]

I’m trying to handle the case where there is no paper in the feeder.

The source automatically displays the message “No page in scanner, add page to scanner?” with [OK] and [Cancel] buttons if there is nothing in the feeder.

I cannot find where I can either get notification of whether [OK] or [Cancel] was clicked, or to disable the source from displaying this message and get event notification for an empty feeder..

Any suggestions would be very much appreciated. Thanks!

I’m brand new to TWAIN and I had originally misread CAP_FEEDERENABLED.

Cheers!

Does anyone have a cross reference between the controls on a source UI and the corresponding capabilities?

Thanks much!

What is the product name of your scanner?

The scanner we’re using is the Cannon DR-7580

Try setting CAP_INDICATORS to FALSE
