EPSON WF-3640 REFILLABLE INK. WHICH ONE?

[rx7nwp]

Hi there,

I want to use refillable cartridges with my WF-3640, because it is too expensive to use the printer with original cartridges.

My question is, which original Epson ink should I use on my WF-3640, Number 673, 664, 774, 522, 512, 542, etc.?

Thanks.

Marcelo

Searching the web I found that the WF-3640 uses pigment ink, so 502 would be a match for pigment ink.

My bad. It is 542 the code for the Epson inks which go with the WF-3640, which are all pigment inks DURABrite.
