Shhhhhhhhhhh, don't give them any ideas.

It'd be way too easy to claim that the ink is past it's best-by date, and that they want you to have a trouble free experience with their ink, so they are disabling that bad expired ink.

Doesn't ink expire normally after a few years?

toner cartridges last forever. I've only used 3-4 over the past 20 years, including the replacement stored for years after I bought it my printer because I assume they would pull that intro-cartridge horseshit but they didn't - they still won!

It's horrifying to think that any ink that I might have stocked up maybe 2 years ago during a sale could be unusable.

Plus, since it's a consumable, it's much harder to return a defective ink cartridge once the packaging has been opened.

"Oh, not ink bought in Utica, no, only Albany ink."

Lexmark already does this with their toner cartridges on mid-size business machines.
