The Data Capture Server creates and manages OCR worker processes according to product licensing. Each worker process hosts an instance of the OCR engine, and can process up to four documents simultaneously. The more worker processes available, the better the OCR processing performance will be.
When the Data Capture Server Windows Service is started, it calculates the number of OCR worker processes to create in different ways, depending on the type of license(s) available.
If your system is not licensed with any of the below licenses, and your Data Capture Server is not configured to perform bar code recognition, then either the ImageProcessingSettings sub-element or the XMLImportSetting sub-element in the Data Capture Server configuration file must be enabled in order for the Data Capture Windows service to successfully start. For more information, contact your system administrator.
