HP 8610 replaement cartridges not recognized as valid

[OldTsar]

Bought new cartridges as my cyan had run out and printing was blocked.

The cartridges are HP and the same model, 950 for black, 951 for the color, but i get an error that they are incompatible.

Welcome to the HP support community.

I understand that you are getting cartridge error, I am glad to assist you.

Reset the printer

Reset the printer to recover from printer errors or failures.

1. If your printer has a rechargeable battery, remove it.

2. With the printer turned on, disconnect the power cord from the printer.

3. Unplug the power cord from the power source.

4. Wait 60 seconds.

5. Reconnect the power cord to a wall outlet and to the printer.

   NOTE: 

   HP recommends plugging the printer directly into a wall outlet.

6. Turn on the printer to complete the reset.

Clean the ink cartridge electrical contacts

Remove any debris or buildup from the contacts on the cartridges.

1. Open the door or lid to the cartridge access area. Wait until the carriage stops moving before continuing.

2. Push in on the cartridge indicated in the error message to release it from the carriage.

   

3. Wipe the copper-colored contact on the cartridge with a lint-free cloth.

   

4. Slide the cartridge into its color-coded slot until it clicks into place.

5. Repeat these steps for any other cartridges indicated in the error message.

6. Close the door or lid to the cartridge access area.

Turns out that the printers are region locked.  On the printer, it does not disclose this, so when you order cartidge by model but not by region, it will not work.  Had to talk to advanced support on the phone to get them to reset the region of my printer from North America to Europe.
