ET-2720 Ink: The Original 522 Model — and the ET-2700 Trap The ET-2720 is one of the models that defined the 522 family: Epson's own page specifies Replacement Ink 522 Black (65 mL) at 4,500 pages and 522 colors (65 mL) at 7,500 pages, all dye ink, measured on the ISO/IEC 24712 pattern.
Its name twin is the trap: the ET-2700 takes 502 bottles — bigger (127 mL black), pigment-based black, lower color yield, different keying. One digit separates the two printers and their bottles do not fit each other's tanks. ET-2720 owners should walk past every 502 listing, including ours for that family.
Singles for the tank that's low, the set for a full reset — both covered by our lifetime warranty, with free returns for a year.
