OfficeJet 6978 won't print cyan

[HJML]

The printer won't print cyan anymore, regardless of what device sends the request to print. We have tried on several laptops and phones. I tried uninstalling and reinstalling on my main laptop. However, when trying to reinstall the application, it said another application was in the process of installing and it couldn't do the install. There is also a firmware update that needs to be updated as well. Things I've tried:

1. Cleaning print heads

2. Align Printhead

3. Clean Smear

4. Hard reset of printer (removed cartridges, unplug, wait 3 minutes, plug in an print test page) - no cyan printed

5. Photocopied something blue - printed pure magenta

6. Removed orange nubs on print cartridge
7. Completely replaced cyan cartridge (also removed orange nubs on that one)

8. Uninstalled program from laptop

9. Reinstall program on my laptop- not successful

10. When it wouldn't reinstall, I followed directions through the virtual assistant to do all kinds of things, including rebooting routers, computer, and printer. There was also something done through the C prompt with unregister and register. The "register" part didn't work.

11. After following all directions to reboot and reinstall, my laptop still said that another program was running to install the printer.

My question...if it's not printing the cyan regardless of which device sends the print job (ie. phone, other laptops), which cartridge I replace it with, or how many troubleshooting attempts I do, does this mean the printer itself is shot?  Or could it be some glitch in the inability to update the firmware through my computer? Trying to avoid more hours of troubleshooting (not that I have much left that can be done) when it won't even install the basic driver at this point.  Help!

I just ordered 2 902 yellow ink cartridges, they were delivered on Dec 2, 2020 dated  2022/10/20 and they were manufactured in Malaysia. 

 Are these safe to use, if not is HP going to send me 2 yellow 902 ink cartridges that actually work to make me whole?

ONE for the cartridges falls in those dates, but the other is later, 2022/10/02, and it doesn’t work either. I tried to reach out to HP Technical support, but it said my printer is out of warranty and only gave me the option of a virtual agent or back to this community. I also tried to follow the link to set up a ticket, but it said I was unregistered. When I tried to register, it said my user name was already in use. What do I do now?
