I purchased my Image Class MF743CDW in 2019. A couple of years later I also purchased a set of replacement cartridges as backups since they had reached ~50%. I don't print a lot so the replacement cartridges have sat for about 2 years. Now my printer is telling me that my original toner cartridges have "Reached the end of their life" and keeps preventing me from printing until I reset the error message. This is very frustrating since my printer is located downstairs and I have to keep walking down to reset the printer.
I went ahead and replaced all the cartridges even though they still have ~25% to 35% toner left in them. The New toner cartridges are official Canon cartridges purchased directly from canon in unopened boxes about 2 years ago. After I installed the new cartridges my printer now says "The cartridge has reached the end of its life" on all the new cartridges. I have tried powering down the printer, reinstalling the cartridges and nothing seems to reset the error message or recognize the cartridges as "new". I refuse to buy new cartridges again. If I can't resolve this I'll go buy another brand of printer. What else can I try? I want this error message to stop, not just reset it every time I have to print.
