I'm not sure whether Epson even use a wet sensor or whether some of the chips just use a print-count to declare a cartridge empty...
The 3rd party chips that I use (from ebay) don't have wet sensors for sure, I haven't pulled apart an OEM cart yet to see if it's got a wet sensor. But the 3rd...
So is this the platen pad for an Epson NX430?
If that is... it looks easily user replaceable, and anyway, I've put a tissue on it before and Ink just drained right into the tissue.
