Trying to Scan a SimulScan Readable Form and finding that the image is captured before you are ready? Change the Auto Capture Sensitivity - I find 5 for larger forms to work the best- but you can play around with the sensitivity until it matches your teams or individual needs.
-> under Edit--> Template Settings--> Auto Capture Sensitivity. Set the Sensitivity of the auto capture based on a scale of 1-10; where 10 is the highest.
