In this situation, I would suggest downloading and installing the scanner driver using the link<A href="https://www.usa.canon.com/internet/portal/us/home/support/details/printers/color-laser/color-imageclass-mf644cdw?tab=drivers_downloads" target="_self"> HERE</A>. Once the scanner driver has been reinstalled, you can try using the MFscan utility again to see if it can scan. If it can, you can try scanning again from the operation panel on the MF644Cdw.</P><P>&nbsp;</P><P>We would be happy to assist further&nbsp;with the issue. To provide some feedback or some troubleshooting steps, we would need some additional information. If you could reply to this message with the information below, we can provide some assistance.</P><P>&nbsp;</P><OL><LI>What version of the Mac or Windows operating system are you using on your computer?</LI></OL> Fri, 29 Oct 2021 21:34:56 GMT https://community.usa.canon.com/t5/Office-Printers/MF644CDW-Questions-Prior-to-Waiting-for-Tuesday-9-7-21-For/m-p/354449#M14753 Hector 2021-10-29T21:34:56Z
