I have a HP officejet Pro 8100 . I changed the black ink cartridge 950. Now the power light and the light under the cartridge keeps blinking. I don't know why this has to be so complicated. It's just exchanging a empty cartridge with a full one. Of course my warranty ran out yesterday. Story of my life.

I see that you're having issues with your printer. I would take a look at the document below it explains why the lights are blinking with possible solutions.
Let me know how it goes.
