I came across this video of someone installing a CISS with a wf-7830, but it's European. People are asking how he rendered it chipless, he replies that the EU does not allow Epson to be rendered unusable, which I assume means it's already chipless. If that's the case, do you suppose they sell wf-7820/40 over there as well in chipless format? Would it be an option to have one imported to the US?
In case I can't post links to YouTube, here's the video title: Ciss continuous ink system video for Epson WF-7840dtwf printer
