imageCLASS MF267dw II - Canon-branded Toner & Drum registering as counterfeit

[mjo21]

I installed brand new Canon-branded 051 Toner and Drum cartridges in my MF267dw ii. Counterfeit errors appeared, preventing me from printing. I updated firmware, ran the cleaning function, cleaned all metal connections, power cycled the printer, and performed a factory reset. These errors are still appearing. There is no option to turn off Genuine Mode. This printer is only a few months old.

To add to this... I was using a Canon-branded toner cartridge and a third party drum before the errors and it was working perfectly fine. The errors then randomly appeared one day.
