I have a pdf with text and images (scanned) and for obtaining text from pdf

i use ocr tool of laserfiche. Its working fine. 

But via sdk laserfiche , ocrengine not working , not obtaing text from images of pdf. 

So i use code via sdk snapshot and next ocr via sdk its working fine, but 

only client laserfiche is open.

There is code:

 using (C_AU.ClientManager clienteLaserFiche = new C_AU.ClientManager())
                    {
 
                        IList<C_AU.ClientWindow> carpetasAbiertas = clienteLaserFiche.GetAllClientWindows(C_AU.ClientWindowType.Main).ToList(); 

                        C_AU.MainWindow carpeta = carpetasAbiertas[0] as C_AU.MainWindow; 

                        C_AU.GeneratePagesOptions opcionesCat = new C_AU.GeneratePagesOptions(); 

                        opcionesCat.ShowUI = false; 

                        List<int> documentos = new List<int>();
                        documentos.Add(915);                        
                        carpeta.GeneratePages(documentos, opcionesCat);

                    }

next ocr al id document 915

 motorOcr = C_DS.OcrEngine.LoadEngine();
 motorOcr.AutoOrient = true;
 motorOcr.Decolumnize = true;
 motorOcr.OptimizationMode = C_DS.OcrOptimizationMode.Accuracy;

motorOcr.Run(C_RA.Document.GetDocumentInfo(Convert.ToInt32(915),varConexion.varSession));
