Re: Hacking the Xaar 128 printhead

Hi, I'm not intending to formulate my inks, but I'd like to avoid buying water based inks (whomever formulated them) if they will ruin a 200€ printhead.

I'm operating a 3DS Projet 660 since a few years, so I have quite a bit hands on experience with this technology.
