I am curious about user's experience with Canon toner cartridges and end of life warnings.
My experience with starter toner cartridges in my MF634 is that Canon generates end of life warnings after two years, even though toner has 20% left.
If I install new toner cartridges (045 for the MF634), will I start receiving end of life warnings after two years even though the toner is not exhausted? Or does this only happen for starter cartridges?
Does the end of life warning depend on when the toner cartridge was manufacturered? I was looking at 045 cartridges on ebay and some of them were manufacturered in 2017 or 2018.
Why are the cyan toner cartridges more expensive than the yellow or magenta toner cartridges?
