Officejet 8710 printer says all cartridges can't be read or are missing. But they're fine

[Tricz]

• QMy OfficeJet Pro  8710 printer (which has the instant ink subscription) was saying the ink cartridge was missing or damaged for all colors. It was printing fine so after some digging I saw my credit card was expired and updated my credit card info. After a few minutes, it then changed to tell me that my yellow cartridge needed to be replaced, so I replaced it with 1 you sent me. Then it told me blue needed to be replaced so I replaced blue with 1 you sent me. After replacing blue, it's now again telling me they're all damaged or missing. But if I remove the blue cartridge, it can then read the rest and tells me blue is missing.
