Printer Ink Cartridges & Print Quality

I am having the exact same issue as so many other people posting here. I have an older model device (OfficeJet Pro 8720) and I am using genuine HP ink cartridges, the exact ones required for my model (952XL), and the same ones I've been using since I acquired the device. A few days ago, I had to replace the Yellow (Y) and Cyan (C) cartridges. The printer acknowledges the Cyan, but says the Y is an "older cartridge" and can only be used on older models and to contact customer support "if I don't have an older model".  My printer *is* an older model and this is the exact cartridge it needs, but I am blocked from using it because it won't accept the Y cartridge. I've spent several hours working my way through trouble-shooting suggestions offered by the virtual assistant, but it's a dead-end. Is there truly nothing we can do? I am beyond my warranty date, and I do not wish to pay for a support plan to solve a problem that HP seems to have created in order to make us buy more ink? And it seems so wasteful and unnecessarily expensive to retire a perfectly good device--with two new authentic HP expensive ink cartridges in it! What are we supposed to do? Does HP have any solution for us? There must be some way to convince my printer that it has received the right ink for both cartridges, especially since it recognizes one of them and they are identical, genuine HP products, that should fit this device, and which were purchased at the same time...please help?
