Why does my Kyocera ECOSYS FS-3920DN Printer say 'Check waste toner box'?
- MMelanie MirandaSep 7, 2025
If the message 'Check waste toner box' appears on your Kyocera printer, it indicates one of two situations: either a new waste toner box needs to be installed, or the current waste toner box is full. Install a new waste toner box to resolve this issue.
