I use the top feeder tray for scanning multiple pages. All of a sudden after scanning previous documents from the feeder tray, I started my next scanning project and when I place paper in the feeder tray the printer beeps acknowledging the paper is in the feeder tray. On the MF Scan Utility, I select the Document button to start the scanning job, the printer does not feed or scan the documents in the feeder tray, the printer starts to scan the platen glass and not the feeder. I have the utility set for Auto Mode. I changed the Auto Mode the Feeder and the same thing happens.
