Check the toner/drum cartridge. reboot the printer. This could've a high voltage power supply issue.

no reset code on those ones, just a sensor that detects new waste toner bottle. Just clean the sensor ( photo interrupter) inside the machine.

the waste toner bottle should be below the toners themselves as seen here:

I had something similar happen with a Magenta cartridge. My only option was to call Minolta. After hours on the phone they finally agreed to replace the faulty cartridge.

I suspect that from time to tame we receive a cartridge with a faulty chip.

Might be the senor that bottle acturates is bad or has toner on it!!! clean the sensor

You can press the 'rotate toner' button which is the blue one next to the toner indicators on the top panel or you can open it up and with two hands on either side of the entire cartridge, turn it manually. You will hear clicking sounds as you turn it. I've done this safely replacing all four toners twice over now.
