With PR#12699, on every periodic discovery run, this printer’s supply state shows a change, ie paper tray replaced or toner cartridge being empty:
2021-04-02 18:35:11 Toner Black Toner Cartridge is empty
2021-04-02 18:35:11 Toner MP TRAY was replaced (new level: 100%)
2021-04-02 12:35:11 Toner Black Toner Cartridge is empty
2021-04-02 12:35:11 Toner MP TRAY was replaced (new level: 100%)
2021-04-02 06:35:11 Toner MP TRAY was replaced (new level: 100%)
2021-04-02 06:35:10 Toner Black Toner Cartridge is empty
2021-04-02 00:35:11 Toner Black Toner Cartridge is empty
2021-04-02 00:35:11 Toner MP TRAY was replaced (new level: 100%)
(neither of these state changes are actually the case.)
