Incompatible ink cartridge z10

[ktvoor]

Bought genuine cartridges a few weeks ago at costco for my officejet pro 8610 printer. However I am getting an incompatible cartridge error. Printer is expecting z20 and new cartridges are z10. I believe a regional reset is required. Please advise.

What country are you in?  The new cartridge may have a marking like -Z10.  What is the marking?  Check the markings on the cartridge you removed as well as the other cartridges in the printer - are they the same Z number?

On the front panel of the printer go to the home screen and press the ink droplet icon at the top of the screen.  Next touch the black rectangle.  At this point a new window will open that says "installed cartridge" and "Supported cartridge".  What are the cartridge numbers listed?

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 need to have the full featured driver installed to generate the codes needed to reset the region.  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.
