Thanks for the post.
I understand that you replaced the cartridges and black is not printing.
Not to worry, I will be glad to help.
Are you using genuine HP Ink?
Have you tried any troubleshooting steps on our own?

For other troubleshooting steps, please refer to this HP Article for assistance.
Please try the steps and let me know how it goes. Good Luck.
