Sara,
There is no capability that gives you the ability to pause the scanning process in the Twain Specification.
Once a scan request is started, the Acquire function does not return until all pages are scanned.
However, you do not have to scan all pages in the feeder. You can specify the number of pages to scan before acquiring using the Transfer Count capability.
For example, if you have 50 sheets in the feeder and you want to pause after 25 sheets, you will have to call the Acquire function twice, and specify 25 as the transfer count before you do that.
