Hi there and welcome
Was it doing this before you replaced the print head?
Please let me know.
It would only do this if its detecting issues with the printhead.
Can you remove it, then put it back in again and tell me if it still does this please.
I am asking for no money.... I will repeat what I asked you to do
Can you Press and hold the Settings button, and then press OK”
does it then stop?
It will have either settings or the wrench on it.
