This is an optimization method that can be used to improve performance. If this method is not called, there is a slight delay before the first scan is started because the control must first load the ISIS drivers. This method should only be called one time.

The following properties affect the ISIS drivers and can cause them to be reloaded:

• Output.FileType property
• CreateFiles property
• UseCompression property

If the properties need to be changed they should be modified and then this method called so the control is ready to scan. This results in the scan starting immediately when the ScanSingle or ScanBatch methods are called since the ISIS drivers have already been preloaded.
