Regionalization reset for Officejet 8620

[Jorivera]

My HP is rejecting the latest batch I purchased from Costco. Turns out my latest empty one  has no region (there is no Z# )," and  the new ones I purchased are actually for US and Canada. 

So, how to now get the appropriate local, correct OEM cartridges to work?  I understand that Regionalization reset is the answer to my problems.  

Followed the instructions by Bob_Headrick on this post. https://h30434.www3.hp.com/t5/Inkjet-Printing/I-need-a-regionalization-reset-for-my-inkjetpro-8600/t...

I've created 2 cases and both of them has been closed:

3/5/2020 - Case Number [edited]  - Created CRM:[edited]  - Closed on 3/7/2020

3/7/2020 - Case Number [edited]  - Created CRM:[edited] - Closed on 3/8/2020

HP does not want to honor my ink cartridges warranty by providing regionalization reset for my printer.

What else I can do?
