Sometimes, after scanning (with OCR), an additional scan is not possible form the scanner itself. The situation usually recovers after a few minutes and scans are possible again. I can't reliably reproduce this but this seems to have started relatively recently in the past months ( fyi @pedropombeiro )
Note: I can't exclude external factors, like network issues, but consider these unlikely.
