I have been running in circles trying to get a Canon support person by phone. My printer, purchased 2023, will no longer print duplex. I have tried all of the troubleshooting steps that are suggested online (resetting modem, updating the driver, etc.). According to printer settings it is on ECO--duplex printing. In the print dialog box I select double sided "on" and still, single sheets are being printed.
In a side note....I can't reach out to support without having my printer registered. I have the receipt, but I can't get it uploaded to registration even though it meets guidelines. Any suggestions? Thank you in advance.
