Have a Canon TS6420 desktop printer that is barely a year old. It was printing last week and now it will not print; message on screen says 'shut down and contact service center'. I have not printed anything in a week or more. Have unplugged, rebooted, etc. and still get the same message. Help?

This error is associated with possibly a paper jam or a ink cartridge problem. Check the printer for any paper in the feed path also reseat the ink cartridges then power the printer off for a minute and back on.

Thank you; have tried both of those but will try again! Frustrating since it’s barely a year old & rarely use it. Have changed toner cartridges once. Thanks again!
