TR8550 not recognising genuine ink cartridge

[rosieinfrance]

Have recently replaced Yellow ink cartridge with a genuine Canon ink cartridge, I have only ever used genuine cartridges, and support code 1412 is showing: The following tank cannot be recognised.. Will not allow me to print.

Would appreciate advice as to how to proceed

Thanks

I've encountered the same problem. Sounds like Canon has manufactured a duff batch.  Never happened before!
