TS7720 Message: There is no paper in the [bottom] cassette. But I want to print from the back tray!

[Relztrah]

I'm using the Canon Pixma TS7720 with Linux Mint 22 Cinnamon. Normally I can print with paper from the rear (vertical) tray but for some reason today I can't. I haven't changed any settings. 

I looked at the printer settings and everything is OK to print from the rear tray. Yes, there is paper in the rear tray. I deliberately removed paper from the bottom cassette tray thinking that this would force the printer to pull from the rear but instead I hear the grears grinding, looking for paper in the bottom cassette tray and then get the above message. 

Any ideas?

You may have already tried one of more of these steps to try and resolve it. I suggest you reboot both printer and pc before taking any other steps. 

To configure the Canon PIXMA TS7720 for rear tray printing in Linux Mint 22, you can use the CUPS web interface by navigating to http://localhost:631/printers/, selecting your printer, and adjusting the InputSlot option to Rear. After making changes, ensure to restart the CUPS service for the settings to take effect.
