Lexmark scanner suddenly won't work under Catalina
I have a Lexmark CX410de multifunction printer. I attempted to scan a document but find the scanner function is no longer operating. I deleted the printer then added it back under Preferences. The printer no longer has a Scan tab on the icon. I then hard wired the printer to the MacMini and was able to install the printer with the scan function tab. But now I find if the printer is not cabled to the Mini I cannot scan. The print function works wirelessly but not so for the scanner.
Any ideas? I think I've exhausted every idea including downloading and installing new Lexmark drivers and to be honest I don't know if the printer is using the new dirvers when I add a new printer
