DTP: OCR option while scanning: strange behaviour

Hello all,

after having scanned documents, DTP sometimes activates the OCR option and sometimes not. In the settings panel for the new document, the option sometimes is active and sometimes not. It is not possible, to change the option. How can I make sure that OCR is always active?

I am proceeding this way:

  • File --> Import --> from scanner or camera
  • Select my scanner (CanoScan LIDE 110)
  • Scan a page with parameters: PDF, Black/White, 300dpi

Best regards
Joerg
