564 Print Cartridges not working in my HP 4620 that was purchased in Germany

[JohnSin100]

I moved from Germany to the US and my new HP 564 ink cartridges are not working in my HP 4620 All in One inkjet printer. The equivalent cartridges in Germany are the 364 ink cartridges. I place one 364 in the printer and three 564 and it recognized the 364 but not the 564's. Do I need a firmware update to tell the printer its US now? I did find the firmware for the HP 4620 e All in One but the firmware file did not recognize the printer.

Hi @JohnSin100

Welcome to the HP Support Community. I'd be happy to assist you.

Find below the compatible ink cartridges for HP Officejet 4620 e-All-in-One printer

HP customizes some printers and ink cartridges to meet local customer needs. If you take your printer from one country/region to another country/region, you might not find ink cartridges with the same number on the label as your original ink cartridges. If you install an ink cartridge with a different number on the label, you might see one of the following error messages:

• Incompatible Cartridges

• Cartridge Not Intended for this Printer

• Incorrect Cartridges

We need to perform a regional reset on the printer to resolve this issue.  

  

The reset instructions are specific for your printer and performing those steps on a different printer may brick the device.  

I've sent you a private message with reset instructions, follow the reset instruction to perform a full reset and re-initialize the printer.
