My MF4450 has been giving me outstanding service for about 10 years. Just today the driver seemed to get wiped out, perhaps because I deleted an AI copilot app that had automatically installed itself recently in an update). At any rate, the 'fax' functions on the printer and the print-to-PDF appear and indicate they're working, but not the laser printer itself. Also, the print-to-PDF function failed to work. Any suggestions? I'd really like to hang onto this printer.
