3800 Pro not responding

I’ve installed the Pro inks into the 3800, and when I use the 3800Pro printer in Print tool, It does not respond at all. When I try to print paper with the 2800 K7 printer, it prints a Piezo DN negative!
I’ve installed the curves for Pr03800 from piezography, but things are the same. Can you help?

please share screenshots so we can debug things

the 3800 shows as not connected in these screenshots. Delete this printer for sys prefs. Turn the printer on, connect it via USB, and then run the install command again from the curves folder and it will work.
