HP Smart Tank 670 printhead

Aug 14, 2023
Hi Everyone,
First time writing here.

Recently my HP Smart Tank 670 stopped printing red ink, all the rest was fine. After looking things up, the problem usually comes from the printhead, which is a pretty cheap product.
I bought an original one and replaced it (a pretty easy process).

Now all lights are blinking and I can't print anything...
I've turned it off and on and also gave it a few minutes with the power cable disconnected and it stays the same.

Help appreciated :)
