I have had these in the basement hidden from view.
They are Z3100 only, I have a 3200 now.
There are three of them full of course, new, but long time out of warranty (2006?). There are some expired print heads too I could send along with.
So I don't want to toss them as I'm sure they are fine, make me a offer and I can post them to you.
