Everything is tested fine except the document feeder. It always says "No original in the feeder", when I try to scan papers by the feeder. I do put my papers (Letter size) in the tray, but for some reasons they can not be detected. Is there a paper sensor or something that blocked? How can I check? Thanks</P> Wed, 13 Sep 2023 07:50:33 GMT lserlohn 2023-09-13T07:50:33Z https://community.usa.canon.com/t5/Office-Printers/My-new-printer-MF743CDW-can-not-detect-documents-in-the-feeder/m-p/436294#M20239 <P>Hello, I just purchased a new&nbsp;MF743CDW.
