I have an HP DeskJet 916c installed (via USB) on my linux (Gentoo) server. I got it running via CUPS.

However, I recently changed the cartridges and haven't found a way to re-align the color with the black one. Under windows it's in the toolbox from HP;

Any ideas on how to do it?

It doesn't work on my 916c....

I would email HP Tech Support and see what they say. Also search HP tech support. I just got this from a quick search. There might be a more specific detail for that model.
