8600+ Locked into Z20 despite being in the US

[NathanLeitch]

I need my printer region to be reset. I guess we used z20 ink despite being in the US and now our new correct HP Brand z10 ink won't work. I was unsure of how to contact HP as is just kept taking me back here. 

Thanks,

HP introduced regionalized cartridges (Z10, Z20, Z30 and Z40) for the previously universal 950/951 cartridges in about January 2017.  The printer will "lock" itself to the first Zxx cartridge installed in the printer.  If you are in the US/Canada you will need Z10 cartridges, but the printer may have been locked to another region by accident.  In that case you will need to have HP perform a "Regionalization Reset".  You will need to Contact HP to request a "Regionalization Reset". There should not be any charge for this, it is covered as part of the cartridge warranty. You will need to have access to your computer and printer while on the line with HP. You will also need to have a set of cartridges for the new region, once the reset is complete cartridges from the original region will no longer work.  HP's web page on the subject is here.

The regionalization reset is covered by cartridge warranty, see the document here for information. To get warranty coverage you will need to go to the Contact HP page, then enter the information for your printer.  At this point it will likely say "Manufacturer's warranty has expired"  To the right of this it will say "See details".  Click the "See details" link, which will open another page with more details.  Near the bottom of the text will be a paragraph that says : 

HP has checked your product information, including the product and serial numbers, to determine your warranty results.

The legal warranty expiration date is based on the date of purchase, as indicated on your receipt. If you feel these results are incorrect, you may submit a dispute for review. Dispute this >

Click on the "Dispute this" link which will ask for some additional contact information.  Fill out the contact information, then in the bottom section select:

Dispute reason  

  Issue with my Accessories, Supplies and/or Software.

In the comment section indicate that you need a regionalization reset and the cartridges are in warranty.

I have also seen folks have success asking in the HP Facebook Support group here: https://www.facebook.com/HPSupport/  The Facebook page is only active during business hours (looks like until 6PM PDT), you may have to wait until Monday for them.
