https://community.usa.canon.com/t5/Office-Printers/imageCLASS-MF267dw-II-Canon-branded-Toner-amp-Drum-registering/m-p/549818#M26626 <P>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.</P> Tue, 20 May 2025 19:46:18 GMT mjo21 2025-05-20T19:46:18Z https://community.usa.canon.com/t5/Office-Printers/imageCLASS-MF267dw-II-Canon-branded-Toner-amp-Drum-registering/m-p/549818#M26626 <P>I installed brand new Canon-branded 051 Toner and Drum cartridges in my MF267dw ii.

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.</P> Tue, 20 May 2025 19:44:56 GMT https://community.usa.canon.com/t5/Office-Printers/imageCLASS-MF267dw-II-Canon-branded-Toner-amp-Drum-registering/m-p/549819#M26627 mjo21 2025-05-20T19:44:56Z
