On clicking the red scan button, a check is performed to ensure that a scanner is available. If there is no available scanner, a message will appear in the messages box to that effect.
To recap on the purpose of the the red scan button, this is a one-click solution that allows a loaded scanner document to be scanned and then OCR'd in one step. If there is no scanner available to you, but you do have an OCR-able image, just use the OCRit button instead. Best to have a scanner installed of course. _________________ Life is too short to spend it in front of a computer
