The printhead is on the cartridge with this series, so if the head is bad, the whole cartridge is bad. HP still sells OEM 21/22 ink, but it is not stocked in stores. Any store stock is almost certainly "high risk" dead stock that isn't getting any younger. I would not put much faith (if any) in NOS OEM inkjet carts like this because they tend to be shot if they aren't stored right (note: If it came with a unit, sure, but I won't seek them out) unless it was cheap and the use by date is within reason.
You're better off with third-party ink that has been checked and vetted on these. If you have trouble finding the OEM inks, the 3rd party inks are usually more plentiful (albeit usually not sold in stores and usually only available online). This is in contrast with NOS toner, which is usually fine.
You need to be wary of super old NOS toner too (like NOS LJII/III/4 toner). They are mostly dead stock because of component wear and toner leakage (and 90s NOS toners in general). As long as NOS toner is within a reasonable manufacturing time, you have a better chance of getting a good NOS toner than NOS OEM ink.
If you have cleaned the contacts on both sides (you can use disposable eyeglass wipes for this) and it continues having issues, look into aftermarket ink from a good vendor; it's your only shot at getting ink that isn't prone to being no good just because it's old stock short of buying from HP online.
If that doesn't fix it, see if you can find a print mech from a junk unit. These all-in-one cart designs are prone to electrical wear on the contact side as they age due to poor contact and electrical shorting. It takes longer to occur on old models with better mechs, but newer ones tend to fail reliably within ~3-4 years.
Authors' Note: The newer printers with the printhead in cartridge design (starting with HP 6X series carts) are more prone to failure due to this, to the point that it has become a HORRIBLY common failure for these printers. If the strip has wear or charring, the printer is toast, especially with a corresponding cartridge burn mark. Good luck fixing it :(.
PS: You will probably find the donor is being discarded for the same failure. Nobody fixes this, NOBODY.
Use this guide to get the printer apart, which is part of gaining access to the print mech if you find this is damaged.

@nick any idea about this one?

@oldturkey03 Can confirm HP no longer makes the ink in capacities it is easy to come by, 3rd party or risky dead OEM stock to try new carts.
