I have a imageCLASS MF269dw. The printer has indicated no toner left for months. Toner level is at 0%. Drum Cartridge is at 70%.  Yet, the print quality is fine. I didn't plan to change the cartridge until the print quality is truly bad. I'm on my 2nd toner cartridge since purchasing the printer in 2020. I am using a genuine Canon cartridge. Counter is at 6844 -- though I need someone to tell me what that counter means.

If there is nothing to worry about, how do get the printer to recognize the toner level. It seems it starts warning me way too early to buy another cartridge.

Thank you!!
