I have been using MS Office Document Imaging: Scan New Document with my HP scanner for a long time using Office 2007 and Windows Vista 64. Now each attempt to scan with this program returns the error "Unable to initialize scanner. Check scanner connection and scanner software." I am able to scan with Windows Fax and Scan with no problems. I have run Office Diagnostic with no problems found. I have installed all available windows updates. How can I get MS Office Document Imaging: Scan new Document to work again?
