We own an HP 7100 Deskjet printer and recently when trying to print, I received a “supply expired” message for my nearly new Type 14 color ink smart cartridge.
Due to some apparent faulty thinking in the HP engineering department, they decided that they would protect consumers from bad ink damaging the printer mechanism. The cartridges have a built in expiration mechansim that consists of a tiny microchip on the back of the cartridge.
Ok, so why can’t you simply set the date back a few months? Well, I tried that but it still did not work. The cartridge was still 62% full but totally unusable, what a crock! There have been hacks for third party refill cartridges, but some may  or may not work for you.

It’s bad enough that you pay nearly $40 for a so called smart ink cartridge, but then to have them expire the ink on you really bites the big one.
Since when did a consumer product give a damn whether or not the item broke? It’s obvious the REAL reason is that they don’t want you to use the “black & white” setting or “draft mode” to conserve ink. If you conserve ink, then you’re not buying ink, or not enough ink to suit their sales goals. I would probably not buy another HP for this reason alone. So, when you are shopping for a new printer, check with the salesman or customer reviews to be sure the ink cartridges do NOT expire. Ooops! My customer loyalty to HP just expired!
