Cartridge won't load into the printer

[haireeed]

Replacing the black ink cartridge with a HP 950 X.  The old cartridge "popped" out and the new cartridge will not go in?

Any help anyone can offer?

Hi @haireeed,

Welcome to HP Forums, this is a great place to get support, find answers and tips.

Thank you for posting your query, I'll be more than glad to help you.

I understand that you are unable to install the cartridges for your HP OfficeJet Pro 8710 All-in-One Printer.

This issue could occur if the cartridge slot on the printhead is damaged or the cartridges are not installed properly.

Let's go through a few steps that may help to fix this issue. 

And here are a few steps for you in the link: Replacing Ink Cartridges

If the issue still persists, then the printhead needs to be replaced. You may contact HP phone support for further assistance at the link: www.hp.com/contacthp

You have a good day ahead.

My 8710 series won't accept the exact same new cartridges.  if I read correctly I have to "try" to replace the printhead in order to continue.  what does printhead have to do with cartridge slots?

You cant fit 950 XL cartridge in your printer because your printer is not designed to work with 950 cartridges.

It has nothing to do with a printhead, you must use 952 ink cartridges if you are in US, or 953 if you are in Europe.

remove your old working cartridge from the printer and check for a number on it, and purchase new ink cartridge according to number from working cartridge.

Both ink cartridges look very similar but they don't fit.
