Hacking the Xaar 128 printhead

[Wonko]

It's possible for you to post the electric diagram of the setup? I'm interesting to try the xaar128.

No problem: https://github.com/MatthiasWM/Xaar128

Hello,

I have a specific interest for the Xaar 128 but for a total alien application: I contemplate using it for biotech application as a way for micro-dispensing of specific agents on cell cultures. However, the medium that I need to spray is mainly made out of water (+many different things including salts).
I read in previous posts some of you indicating that the Xaar may fail with water.
Does anyone here experienced with water?

Thanks!

Yes. Water will destroy your head. I don't know how ink is different, but it seems to have to do with conductivity. Maybe Epson heads can do that?
