ImageCLASS MF4890dw "Cleaning failed" (Clean Fixing Unit)

[JjgCanonUser]

I have a canon laser printer, model ImageCLASS MF4890dw. I am getting black streaks on my printed pages. I suspect these streaks are coming from the large roller, visible after removing the toner cartridge. I would attempt to clean this manually but it is locked in place. I do not know how to unlock it.

I replaced the printer cartridge with a new one, as suggested by google AI. I tried to run "Clean Fixing Unit" but it just returns "Cleaning failed." I have no print jobs in memory (I unplugged and re-plugged in after a minute). I do not have a paper jam or a nearly empty toner cartridge. 

Please help, if you can.

Thank you in advance,

John G.
