OfficeJet Pro 6978 not accepting genuine HP 902 cartridge used in printer and refilled

[tlogo]

Hi community - need help.  Last year OfficeJet Pro 6978 I installed and used genuine HP 902 cartridges (set1).  Printing was fine with set 1 and I used the printer until the ink was depleted by normal usage.  I bought and installed another set of genuine HP 902 (set 2).  Printing was fine with set 2.  While using set 2, I refilled the ink from set 1 at Costco until set 2 is depleted.  Now that set 2 is depleted, the printer won't accept set 1 (refilled).   It me an error that related to cartridge protection being enabled, so I disabled it now I get a different error, "remove and reinstall the indicated cartridge, making sure is it correctly installed."  Of reinstalling them several times does not work.     

Anyone have a solution?

Welcome to the HP Support Community.

HP does not recommend usage of refilled or non-genuine ink as it damages the contacts/printheads of the Printer.

Please perform steps from here: https://support.hp.com/us-en/product/hp-officejet-pro-6970-all-in-one-printer-series/8289585/model/1...

If the issue persists, we recommend you to use a fresh set of genuine HP ink cartridges.

Let me know if this helps.
