Lexmark scanner suddenly won't work with Cataline 10.15.7
Until a few days ago (about 10) my Lexmark MS310dn printer/scanner worked fine. Now it won't open scanner. I've reinstalled the printer, there is a 'scan' tab. Select open scanner and then I get a message "waiting for scanner", and I keep waiting until the cows come home. I've installed the driver from the Lexmark site (yesterday). The problem computer is a late 2013 27 inch. Catalina 10.15.7. Cannot remember which update the scanner decided not to work from. Everything works ok from our other Mac which is a Mid 2010 21.5 OS High Sierra 10.13.6 so it cannot be the printer. All on the same network.
